GGG EA Tremolo Trouble Shooting

[GGBB]

Seems more and more like something is wrong around or after Q1.  Try bypassing the Q1 gain stage by jumpering from C1-C9 junction to lug 3 of the volume pot or to the output jack directly.  An audio probe would be useful because it will allow you to listen to the signal as it passes each component.

Well guys I'm sad to say I busted the board. while removing a cap I ended up damaging the trace. Maybe it's fate.. I'm going to buy a new board an start fresh. Thanks for all the help! It's been a great learning experience.

Luc_antonio, if you are going to shell out for a new board, you might as well invest in a breadboard as well. I'm guessing, seeing as you've stayed at it (the tremolo) this long, you have something else on the list once it's working. it'll make the world of difference, and save time and boards.

Yeah sounds good, i want to get into building from perf boards or even experimenting and making new designs of my own.  like a distortion/tremolo hahah

That's not busted. Put the cap back, then extend the cap's wire lead along where the trace was, until you reach solid copper (usually best to go all the way to a part-lead). Tack-solder the end. If the bare lead may vibrate and touch something, slip some insulation on or glue it down.

A valuable tip, thank you
