Hey Guys,
I recently purchased the GM40D and instantly ran into two issues.
My Setup:
- Fender AM Std Strat with Custom Shop fat 50s pickups directly plugged into the Amp
- Using only RedBox AE, with no speaker cabinet connected, directly into an Audio Interface
1. At high gain settings (Lead channel, gain ~ 50%, with boost engaged) I expierience a terribly loud high gain squeal, which changes with certain amounts of gain, channel & master volume. It also varies depending on my distance & angle facing the amp: At a ceratin distance to the amp it's completely gone, just hearing the classic 60-cycle hum from my single coils, which can be easily handled with the inbuilt noise gate. Also, at a 90° angle (tip of the head stock facing the amp) it's completely gone and increasing in volume if I face the amp more and more. I also got a Schecter with Seymour Duncan Invaders in it. The Squeal just starts at even higher gain than with the strat. I also heard of the phenomena of EMI, so I turned everything else off in my room (computer, lamps, etc.) but that didn't make a difference at all.
I do know that it's pretty normal, but is there a way to get rid of it? I read smth about shielding the guitar & waxing the pickups, but does this really make that much of a difference? Would really like to hear how it turned out for smb that had the same issue in the past or your overall opinion.
2. With nothing but the guitar connected to the head, there is even sound coming directly out of the head. No buzz or hum or smth like that, it's literally my guitar signal how it wound sound with a speaker connected, just overall high, sharp & harsh. It occurs mainly in crunch, lead & ultra channel, and can get pretty loud the higher I put the gain, volume & master controls. You obviously can't hear it with a speaker connected but it's there and it bothers me, since it really sounds unhealthy. I searched for this issue but didn't find anybody else expieriencing it. I also turned in the amp to my dealer which instantly sent me a new one, just to find out that there's the same problem. I really want to know if it's meant to be like that, or if I just had bad luck, with both amps!
I really dig this amp, and I'd hate to turn it back in. Would really like to know if it's the same case with your amps.
Looking forward to your answers!
