There are currently two versions of the TR-2. The new TR-2 has a PCB that looks like this. The older version has a PCB that looks like this. Make sure you open your TR-2 up to see which version you have before you order.
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 BiColor LED is also supplied.
Now With Flashing Rate BiColor LED Mod — I have added a new feature to my TR-2 mods. I have added a BiColor LED that will posses 2 functions. BiColor LED is included. One will blink at the Rate the Tremolo effect is set to by the Rate knob and the other will show when the effect is engaged. You can purchase the BiColor LEDs here.
