5 Ugly Truths About Building Your Own Effects

I started a few years back modding pedals. It was exciting to crack open pedals and fiddle with the inside bits. I knew very little about what I was doing, but I knew what I had to do. I was handy with a soldering iron and was cheap, so of course I wanted to try to get the boutique sound everyone was on about on a budget. Going from there, I found that for the price of a used pedal and a mod-kit (or an order from a parts vendor) You can buy a kit with everything you need to build an entirely new pedal. There a few things that you have be mindful of.

1) There is A Steep Learning Curve

Can you tell a resister from a Capacitor? Do you own a soldering iron and necessary accessories to complete projects? Do you have a large amount of free time to use on projects of varying difficulty and usefulness? Do you have a some extra cash to blow on something that may or may not work? Well then, you can embark in to the wonderful world of pedal building. That is, right after you learn how to read schematic and gain a basic understanding how/why pedals work. Building pedals can be a lot of fun. It might save you a bit of money after you get the hang of it. Before you get the hang of it, you might have to sink a bit of money, time, and frustration into gaining that grasp.

2) It won't work

Typically, your first time out won't work. If it does, then you are either lucky or the most talented person I've ever heard of. Depending on the project, there are tons of things that can go airy. So if you are skilled enough to make every solder joint solid, there is still a chance that anyone of the components you've installed are improperly placed. Do you understand exactly how a 3PDT switch works, or how to tell which leg of an LED is negative? Even if you double and triple check your schematics and diagrams as your build, chances are there will be a bug or two that don't work. Which leads us to...

3) Troubleshooting

Typically, this is the step that is the hardest. You know the inner workings of your components, your solder joins are flawless, and you can read technical schematics in Chinese. Now is the time to put all that hard work into action. The pedal is built and everything is "correct" but it is still not functioning properly. This is where a multi-meter comes in handing. You may want to brush up on how to use said device to best serve your needs. The continuity function comes in very handy. I've spent many an hour trying to figure out why something wasn't working only to understand that it was beyond me. So I ended up:

4) Getting Help

There is a wealth of knowledge out there (here) on the interweb. I wouldn't be typing now if not for the vast amount of resources that I've found on this subject and many others that can be found on websites and forums. Sometimes it takes a big man (or lady) to admit that they need help. Other times it take someone who has spend countless hours burning his fingers only to wind up with an extremely frustrating paperweight. You'll find that many people are looking for the same answers that you are. If you are having a particular problem, then you can contact some builders personally. There are fantastic communities of builders and prospect builders willing to help us. Sometimes even with the guided help of experts, we still find a way to fail. Which leads us to...

5) Acceptance

Yes, sometimes the best thing to do is to give up. Maybe today is not your day. Maybe you need to walk away and try again later. Perhaps you were a little too ambitious and need to try a simpler project. I have a couple projects that are just that, projects. I started them with a good understanding of what I need to do and still wind up with something that is unsuitable for use. That's Ok. We learn something every time we start a new project. Its not just about to product at the end of the build but what we learn along the way.

Boss BD-2 Blues Drive Mod

So I've been talking a lot about Boss pedal mods lately... there is a reason. Its because I've done a lot of them recently. I really enjoy messing around inside those little boxes and seeing what I can get out of them. It really is a lot of.... fun? Anyhow, Moute Allum has gotten me in a lot of trouble lately. He is putting out a lot of great stuff that I just have to have. I've posted a lot about OD pedals, like here and here, so you know I like a good dirt box. So when I finally got around to actually buy a Boss Blues Driver it was only a matter of deciding what I was going to do to it. I went with Moute again. I chose the H20 mod because it seems to offer what I would like in my little blue box. I took my time with the mod. I thought that this was going to really wow me like the GE-7 I had done before this one. Here is where the pattern breaks. I was able to side-by-side test this pedal with an unmodded twin and the differences were so slight that at times I was unable to identify which was the modded pedal. Now this was far from scientific. I ran both pedal in series so they had to pass through each others buffers, but as far as the great difference/improvements I have had in the past, there was no one thing I could point to and say was much better. Maybe some further testing is in order...

Here is what Mounte has to say:

Boss BD-H20 DIY Pedal Mod Kits - When searching for a name to call this mod I chose H2O because it's the symbol for water. Water can be clear or transparent and it can be light or heavy. This mod transforms the BD-2 into an almost completely transparent pedal letting the true character of your guitar, pickups and amp shine through. Not only is it almost completely transparent, it's also extremely Dynamic. As you turn the Gain knob up on the pedal you can control the amount of gain using the volume control on your guitar. The BD-H2O will react exactly like a tube driven amp. The shriek highs and splaty gain of the stock BD-2 are completely removed. Compared to our regular BD-2 mod this mod has a much flatter EQ.

My regular BD-2 Mod has a slight mid boost and a little less gain than the BD-H2O Mod. Both mods remove the shriek highs and splaty gain of the stock BD-2. The splaty gain of the stock BD-2 is a common gripe I hear about others that offer mods for this pedal. We have removed this issue with this pedal. We also include a Super Bright 3mm White Clear LED. We also modify a resistor to increase the brightness of the LED X3. You can use the LED as a flashlight on stage after the mod, it is that bright, almost blinding. I will boldly state that this is undoubtedly the best mod on the planet for a BD-2. And the really cool part is we won't break the bank with the price of our mods. We offer top quality parts and expert craftsmanship at very reasonable prices.

Boss TR-2 Tremolo Guitar Effect Pedal Mod

A good while back I picked up a Boss TR-2 Tremolo. I like the pedal. I have a Vox Cambridge amp that has tremolo built in but I wanted to be able to switch the effect on and off, hence the pedal. As many people have commented on this particular pedal, there is a little drop in presence when switching the effect on. Go figure right... So I search for a mod that would help with this issue. I found Moute Allum. He offered a cure for a reasonable price.

Here's what Moute says:


Well, you asked for it and here it is. The stock TR-2 is noisy and has a volume loss when engaged. With this mod I have fixed each issue. I have also incorporated my new Dual Stacked Chip Adapter Mod using a very high quality Burr Brown OPA2134PA and RC4558P Chips. The effect is like lifting a blanket off the pedals tone. I can boldly say without a doubt this is now one of the best Tremolos available in a stomp box at any price point.

With this mod I have incorporated a pot that not only solves the volume loss issue but also now allows the pedal to be used as a clean boost with the depth knob all the way down. I also modify a resistor which increases the brightness of the LED. A Super Bright White LED is also supplied.

I'm so glad that I did. The pedal is excellent now. It does add a knob on the side of the pedal. Keeley has a similar mod that replaces the depth knob with a concentric knob. Super sleek. The mod includes some "hi-fi" parts and replaces a in-line op-amp with two 8-pin IC's. I really recommend this mod or one like it if you own this pedal and think you may benefit from it. All the changes it makes are good one. It makes a good pedal great. 

Boss DS-1 Distortion Guitar Effect Pedal Mod

       So there is a lot of mods out there and I would be lying if I told you that I tried them all but I have done a few. Some turned out to be big improvements and others were even bigger disappointments. So how do you know which mod is right for you. Well, I can't really tell you. Maybe you want something completely different out of your pedal, I can't tell you that a mod makes a pedal better or worse. I can tell you which I've done and what I've liked.

       A few months ago I found my self owning a Boss DS-1. Picked it up in a gear trade. I've never been a fan of the pedal. It puts dirt on your signal like a box with the word "distortion" should, but there are complaints with the way it does this. I'm not technically gifted. I'm not going to tell you that it compressed my tone, or sucked it dry, or had some kind of mid-hump/scoop I didn't enjoy. It did seem like the mid frequencies were scooped and that no matter how I turned the "tune" knob I couldn't find a sound that I liked. I've tried the pedal in (bedroom)studio and life setting. I did not like what it did for me. So I then turned to mods to make it do something I did like.

      Research. (Google) so looking into what I should do with this big hunk of orange took some time. I had to find something that I found appealing and seemed like I was capable of. (also the first step could not include "throw pedal away and buy -enter boutique pedal here-") I dismissed anything that said "Metal", or "Crazy", or "Super". I did find a mod that seemed to fit the "make it not sound like crap" requirement. Described  plainly as "vintage mod"

The Mod:

Boss ds-1—Vintage 
Mod Location Mod value 
D5 Led 
C3 .033uf 
R16 1k resistor 
C11 .01uf 
C1, C5 .1uf

     Simple enough. 6 pieces. It took less than half an hour. It made all the difference. The Eq was evened out and the nasty, fizzy distortion was lightened into a more mellow, overdriven amp-type sound. Side by side test proved that the mod had turned a hunk of junk (in my opinion) into something that I'd actually use. The change of the diode really changes "type" of distortion and the resistor and capacitor change the "shape" if that makes any sense. (probably not) The tone knob seems to "work" better. The Drive actually controls the amount of gain the unit produces, unlike before were it just went from a little fizz to a lot of fizz. Level kinda works the same, but the sound sounds more transparent. I even had my non-music playing wife listen and she confirmed the mod made it sound "clear-er" 

    So, if you have a DS-1 That you hate and want something that you don't hate, then do what I did and make your own vintage-y overdrive boosty thing

Boss GE-7 Graphic Equalizer Guitar Effect Pedal Mod

If you are at all familiar with the line up of boss pedals, then you've probably notice their equalizer pedal. If you've used then you may know that it can get a little noisy. Some of this noise is the pedal just amplifying your guitars signal which is going to have a little noise just by its nature. Using a Equalizer is a great way to boost certain frequencies to shape your tone without doing anything else to your tone. It may not turn your twangy tele into a moody jazzbox, but it wouldn't hurt to add it to your chain to fatten up a rhythm section. This pedal has enough flexibility to make you stand out on leads or have a big fat bottom end. No matter what gets moved or replaced on my pedal board I always keep my handy GE-7 around. So if this is such a great pedal, then why the mod? Well, I did mention the noise. The kit that got from Mounte Allum included no less than 6 opamps. As with most of his mods, this kit included some "hi-fi" passive parts. After I installed this kit I was actually surprised at the difference it made. It turned a good little tool into something great. HOWEVER, I'm not 100% sure why, but this mod makes it so that a 9-volt battery is drained in seconds. So If you are looking into this mod, then be sure to have a power supply on hand.

Here is what Mounte Says:

This is very handy tone shaping tool to have on your pedal board. This is actually a very nice sounding EQ right off the shelf. But it suffers from excessive noise as a result of the cheaper components Boss uses. With this mod we replace the cheaper noisy op-amp chips with low noise higher quality chips.

Lower quality capacitors are also replaced reducing noise even more and also adding a more focused Hi-Fi tone to the circuit. Noise is substantially reduced and the signal is passed through preserving the original tone of your guitar. The bypass circuit is also much improved. You will not find a better mod than this anywhere for the GE-7! You'll be shocked at the improvement this mod will make on this pedal.

What Order Do Effect Pedals Go In?

I've asked myself this question so many times, and over the years I'm become inclined to set up a pedal board in certain ways to create particular sounds. There are some general rules to follow or completely ignore, whatever your case may be.

1. Volume.

Volume pedals are very handy tool in a guitarist's bag. It allows you to adjust your volume on the fly, mute your signal for tuning or guitar changes, boost you signal (provided that you running less than full volume) and create swell effects. Personally I like my volume pedals first. Why? Because it create to same effect as the volume knob on your guitar. If your volume runs into you overdrive/distortion then you can manipulate to distortion by changing your volume (ie you'll have a cleaner sound with lower volumes). If this is not the effect you desire then I suggest running the volume after the distortion. This will allow you to change the volume of your signal without changing the distortion level.

2. Wha

I know that this is not typically the wha pedal would fall, but Its where I put it. A wha will manipulate certain frequencies in your signal, mostly the lower-mids to the upper-mids. Your main concern with wha pedals is the voicing and pronunciation of the effect. I've played enough in bedrooms and stages to know that there are huge differences in how the sound is received. I've sat in a bedroom and thought that my digitech rp100 muti-effect pedal sounds great, but when I used it live it sounded like I was playing out of a tin can. ( by the way, never mess with multi-effects. just say no kids. Learn from my mistakes) What you will notice between have your wah before and after your dirt boxes is the presence of the effect. For the most part, the OD and Distortion will want to change your signal frequencies just like the knobs on your amp. The "tone" knob of your Overdrive with play with how your wah opperates. (given that it is on while your using your wha) A wha before the dirt will be less noticeable (more organic sounding). While a wha post dirt will take your whole signal for a ride. This may be what you want. I like a mellow wha, but sometimes you need to be out in front of the sound and make that effect stand out.

3. Dirt

There are many different ways to get your dirty signal, but if your using a stomp box, this is where I put it. Having your Volume and Wha before these pedal gives you more control over the entire sound. I like control. Maybe thats why I have so many choices when it comes to my Dirt Boxes. I have a lot to say about OD/Distortion but you can catch most of it if your follow that link there.

4. EQ  (and other signal processors)

Again, this isn't exactly would you should do, but this is how I like it. Remember how I said I like to control my tone? Well, this is a little part of that. I use my EQ as more of a boost. I set it up to give me a little mid-hump action and maybe a overall volume boost. Some people like to set their EQ and forget it, just let it do its thing for your tone. That's fine, but everything is trying to change your frequencies. If you run a Compressor or Noise Gate of some sort, here is where I would put them as well. Be aware that your Compressor and Volume pedal are not going to play well with each other. Basically, they are doing the exact opposite of each other. If you want comp on your signal and swells. then you have to run your volume after the comp.

5. Delay

I had a Boss DD-3 that absolutely hated be overwhelmed by a distortion. Other than that particular Combo, delay is best left near the end of the chain. I'm not a big delay user. I will use it from time to time to fatten up my sound, but for the most part I like a nice straight sound.

6. Filters

I don't mess with delay much, and I use filters less. In theory, filters behave better at the end of the chain. That way they can have their way with your sound and change it as they see fit. If you are a fan of these then have at it.


So there you have it. I encourage anyone interested in effect to play with them as much as your can. There really is no wrong way to set your rig up and I may be doing it all wrong as far as you are concerned. If you disagree with any of this then leave me a comment below.

Bad Monkey Mod

As far as I can tell the only modding that is really done to this pedal is switching out some capacitors for higher or lower value to effect the tone. I'm totally new at the whole modding ball game but this is what I've found out so far.

If you remove the Capacitor at C5 and replace it with one rated at .1uf then you can flatten the EQ of the pedal. Cutting the mid will give the pedal a transparent sound. If you want to cut the mids even more you can use a Cap with a rating of .15uf.

I pointed out the C5 Cap. It was a little of a wheres waldo. It is right between the knobs and the input jack.

Her are the solder points for C5. Not that hard to find, but its worth pointing out. Just under the knobs there.

There is also a mod for more bass. I'm not sure that this one is as popular as the mid-cut but I'll show it anyways in case you may want to add some bass to you Bad Monkey. Basicly you just follow the same routine. In this case you are changing the Cap at C11 with (again) a .1uf (or .15uf if you like) Cap and then you have bass boost. So Much Bass...

Pictures!

This one is much easier to find. Its basic the lowest thing on the right side.

Flip it over and there you go. The solder points. Pretty easy to find this time.

I haven't actually done this yet, but this is a common mod. You see this mod in the Humphrey Audio "badder monkey" on ebay for 100+ dollars. I bought mine a number of years ago for 40 From Musicians Friend. I't been kicked off the Pedal board because I don't need another "green" style OD when I have my Visual Sound Rout 66. But I may do the mod and use it for a boost or just as another color OD.
