Re: 2 x el84 Rocket thin and shrill!!
ok I see what you guys are talking about so i corrected the issue by connecting the 1M to grnd at the tube socket pin. but the amp still sounds bright and fizzy. not pleasant sounding at all? I've built a few amps and this is by far the worst sounding yet any ideas.

the RC on the vol pot are there to block the dc from the guitar added per the vvr instructions. the board material is bakelite I got from a machinist buddy of mine.
