I currently have a Mesa Boogie Dual Rectifier 3 Channel amp. I love it and think it's awesome, but I'm kind wanting to explore a more classic rock/stoner sound. The Recto does it, but it always has that grainy sound (which is why I bought it; fuzz in an amp is pretty awesome). Does anyone have experience with the Valveking II? I heard someone else play one and it sounds pretty good. The features offer a lot of options. Opinions are very welcome.
