SOLVED Blue Breaker Broken

Had it working, sounded great, then turn it on today and signal cuts when pedal is on. Opened it up and one wire had come loose, resoldered it and now the volume is super low to the point where you can barely hear it with all knobs maxed. Could the TL072 be damaged? Thanks
 
if you have a spare TL072 and the one on the PCB is in a socket, go ahead and switch it out to check and satisfy your curiosity.

what you described could be lots of things, but a damaged IC from a loose wire would be pretty low on the list. take it out of the case and see if it works, then look for stray wires or cold solder joints. try to get it working out of the enclosure before you put it back in the enclosure. if it still doesn't work after you have given it a good exam, post some pictures of each side of the circuit board.
 
Thanks zgrav, just got around to it and still no luck. When I click it on with all knobs maxed it sounds just like volume drops by a few db and bass is lost. No overdrive gets through. All knobs affect the signal
