1.can it do good lower gain Plexi-ish tones? 2.can it do JCM800 mid to higher gain tones? I know to pull off both tasks, 100% , is a pipe dream...but just curious how close it gets. I have a couple friends that rave about it, so I hope to try it out soon. That said, I have yet to hear a real convincing demo. Most sound a bit fizzy. Thanks for the thoughts .
