hooky_lowdown Posted June 24, 2018 Share Posted June 24, 2018 Was given a little fender solid state guitar amp (frontman g15) got it home and turned it on, to find an annoying constant hum. Turned all the pots, hum was the same level, including the volume, with the volume at 0 or 10 the hum was the same. A google search told be these fender amps have a common hum issue from grounding issues. But couldn’t find a conclusive fix. I have zero electrical knowledge, any thoughts what I need to do to stop the hum? Quote Link to comment Share on other sites More sharing options...
jebroad Posted June 24, 2018 Share Posted June 24, 2018 Ive got one of these amps too and fixed it 3 too many times. Is there any noise out of it if you plug anything in? Quote Link to comment Share on other sites More sharing options...
Frank Blank Posted June 24, 2018 Share Posted June 24, 2018 Amp Hum Help is a great song title, perhaps by Bow Wow Wow. 1 Quote Link to comment Share on other sites More sharing options...
hooky_lowdown Posted June 24, 2018 Author Share Posted June 24, 2018 Yes, the amp fully works, actually sounds good imho, but the constant hum is really annoying. Quote Link to comment Share on other sites More sharing options...
jebroad Posted June 24, 2018 Share Posted June 24, 2018 Could be a slightly dead IC. ive replaced the one in mine twice now, its pretty simple to do. It probably doesn't help that i would put a bass through with gain at 11 Quote Link to comment Share on other sites More sharing options...

hooky_lowdown Posted June 24, 2018 Author Share Posted June 24, 2018 Ah! My amp does have output. So guess it can't be that. Thanks anyway. Quote Link to comment Share on other sites More sharing options...
ianrendall Posted June 29, 2018 Share Posted June 29, 2018 Have a look at D-Lab Electronics on Youtube. He fixes a few amps with hum. Lots of other useful and interesting stuff as well. 1 Quote Link to comment Share on other sites More sharing options...
