Last night I completed the Boss Tr-2 Tremolo pedal mod from Monte Allums, minus the flashing LED part of the mod (though I did replace the stock LED and resistor with a white LED). I have done four of Monte's mods prior on various Boss dirt boxes with great results, so I am not a rank novice. The pedal sounds great - much clearer and better overall - but when I put it back on my pedal board I noticed that I can here a faint "oscillating noise", the tempo of which is tied to the rate knob setting, even when the pedal is in bypass. If the noise was present with the pedal in its stock form, I had never noticed it. If I turn up the gain on one of my dirt boxes that preceed the TR-2 in the signal chain it becomes very pronounced. The TR-2 is a current production model - I just got it new a month ago. I have eight pedals on my board currently and I am powering them with a One Spot. Any thoughts would be greatly appreciated!
