I've always been against Les Paul Juniors. I thought they were cheap guitars for posers. Well, that's until I got my custom shop reissue... It's brutal, it's thick, and whether I play it clean or with very heavy distortion, I get amazing results. Now, I also play a P90 through an R4 Custom, and it just sounds terrible cranked up. The aggression is all gone and I sound like a confused jazz player. Bad... Is it "normal" that the P90 sounds so different in my guitars? Are there any other Junior fans who use their instrument for the heavier end of the spectrum?
