i recently retubed my classic 30 due to a really bad feedback problem. It's fixed it a little bit of it but it's still got some feedback. is this normal for the amp, (i pretty much maxed out the gain and volume and played a little and got some feedback when i stop)

the feedback gets really bad when i plug in my english muff'n or my tubescreamer. I have the drive on 0 and the tone and level on around 7-10 on the ts and on my amp the gain is at 10 and the volume is at 1 and anything past 2 makes it go into intense feedback. does this happen to anyone else (more feedback when you plug in a tubescreamer or another pedal)

i really like this amp but the feedback makes me not want it anymore

last, does anyone know how much i could get for this used if worst comes to worst?

thanks

i dont think that a strat would relly do it cuz i dont have noise cancelling p ups and i can walk right up to my amp gain on ten volume ten w/o any feedback, its my les paul that gives me feedback troubles, same goes for my schecter, you might wanna just take a step back from the amp, maybe sheild your guitar(what im thnkin about doing my les paul)

Microphonic =/= regular pickup noise

What happens when you back off on the gain and turn up the volume?

the feedback goes away....

?what is that

i have a rg with two dimarzio humbuckers so would sheilding them help? the single coil produces almost no feedback

Try a different outlet/guitar/cord to make sure it's the amp that is causing the problem.

It might not even be the amp.

i've tried other outlets/chords but i can't try other guitars becasue i only own one and all my friends own crappy guitars


do you think the shop that sold me it would let me bring it back and try out other guitars on it? i bought it around 5 months ago
