Hi all! First off, I'm a first time Gretsch owner and I'll be damned if this isn't the finest guitar I've ever owned. However, I have a bit of any issue that I can't wrap my head around and I'm usually pretty good at figuring out and fixing most problems with guitars and amps. I believe somehow that my problem is specific to my guitar and amp together. I bought the Pro Jet 3 weeks ago and played it through my Peavey Heritage VTX and various drive pedals with no problems at all. I decided to downsize this week and bought a Boss Katana 50. Well, it didn't take any time at all to notice that the guitar in general seemed to be noisier than with the Heritage by a good margin, almost as if it had single coils in it. Also, if I turned either the master volume or pickup volume down it would hum loudly until I turned the volume back to maximum. Here's what I've tried to sort it out: Checked the wiring. No problems there. This model does have the independent volume controls. Tried a different guitar cable and power cable for the amp. No change. Took the guitar to my brother's house and plugged into his Vox AC10 and also his H & K solid state amp. Hum and noise was much less even with higher gain and when I turned the volume down on the Pro Jet, everything went quiet just as it should. So I plugged both his G2622 (dependent volume controls, BTW) and cheap Ibanez into my Katana. Hum was much less than mine and the volume controls on those guitars did not produce increased hum after turning them down. So in the end, it seems there is something specifically about the combination of my Pro Jet and the Katana 50 that just doesn't seem to work together. My guitar is fine with other amps and the amp is fine with other guitars. The only thing I can think of is that there could be an issue with the independent controls on the guitar and the Katana amp. I'm going to switch the wires on the volume pots tomorrow to make them dependent and see if that fixes it. Other than that, I'm stumped for the first time in quite a while.
