Yesterday I went to GC and traded that POS Marshall JCM 4212 towards a Vox AC30CC2. I've been wanting a Brit amp for a long time and since the Marshall turned out to be a lemon I figured I'd dump it while I could. At least now I know 1st hand why people bash on the channel switching JCM 800's - They Suck! Anyway, the AC30 is a nice amp, but I'm having a tough time dialing a tone that I like. I tried the suggested settings on the hang tag, but the overdrive/gain seems to be a little too fizzy/buzzy. Is the distortion on the AC30 supposed to be like that? Or is this amp a lemon too? Any info is appreciated. BTW, I'm trying to get a good classic rock crunch sound. The sound I'm getting now nails Mudhoney's tone, but I'm looking for an AC/DC or Rose Tattoo sound.
