Hi all,
Just picked up a Godin Acousticaster that seems to have an issue with the preamp.
When first plugged in the guitar sounds rather distorted (as if I have the EQ maxed out, but I don't, and it doesn't clean up if I turn the EQ way down either), after a minute or so the guitar starts to generate a rumbling noise accompanied with the occasional pop and / or crackle. At this point the guitar signal has cleaned up lots, but with the rumbling and popping it's unusable. Feels like a capacitor failing perhaps, based more on gut instinct than anything else.
I've checked and changed the batteries (2x9v) and all looks to be ok, can't see any shorts or dodgy joints. That said at some point someone has soldered some resistors to the underside of the PCB (see pic). Not sure if this is a mod, a repair, or from the factory...? The jack socket looks fine.

I am a guitar tech, so have some skill and experience with a soldering iron, but would need a schematic or test values to get to the root of the issue, I understand you don't send these out though.
Can I email someone to get some help on this? Don't really fancy going down the alternate preamp route, need to get the existing one sorted really.
Hope you can help.
Chris.
