...I promise this'll be the last thread I make about this, especially from what I just heard coming through my amp. As many of you know, I've been making threads about tube changing and my biggest question was how much will a tube change affect my tone? My answer? A fuckton. My rhythm channel is as grinding and meaty as before while my lead channel seems to have been reinvigorated and is now absolutely PERFECT. I've always preferred rhythm channel but after this tube change, I'm starting to find it VERY difficult to choose. The lead channel doesn't sound weak or thin. It's like a log splitter without the shrill fuzz. I'd like to thank KailM for the JJ recommendation. This 6505+ that I have now, if it was brutal before, it's world destroying now. I'm struggling right now typing this because I can't wait to go back to my room and crank the hell out of this beast!
