Thanks duhvoodooman.
I finally got around checking things yesterday.
So, the resistors, caps, pots and everything seems to be in place. I did reflow some suspicious-looking joints and I plugged in afterwards to check if anything changed. I didn't have my main guitar around at the time, so I used a crappy bass. And it was flawless. Unity is around 1 o'clock, so I could dial in a huge boost. Happy happy happy, right?
Well not so fast. I checked the pedal with my guitar this morning and it's the same as before. Unity at 4 o'clock, and not much of a level boost above that. Sounds kinda overdriven compared to the bass, too.
Now, the one big difference between the bass and the guitar besides the obvious is that the bass has passive pickups and the guitar has actives (EMG 57-66).
I checked the specs and the EMGs' output impedance is 10kOhms, and the compressor's input impedance is 470kOhms. Could this be a problem? Or is it just that the pickups are too hot for the pedal? If it's the impedance mismatch, should I change R1 in the pedal to a different value? And if not how do I solve this?
Thanks!
