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.
