Well, maybe not "metal" high-gain, but Guns N' Roses type high-gain. It'll be used with many different guitars, but specifically a Fender Deluxe Nashville Telecaster loaded with low output DiMarzio's. Going into the clean channel (volume max and using gain knob for volume, mimicking non-MV) of an EVH 5150 III. I know it's a "metal" amp, but the clean channel is really great on the new ones with the concentric pots. If I'm not mistaken, Kurt Allison (Jason Aldean's guitarist) uses one live on the clean channel. Anyway, looking for something that can go from edge of breakup to crunch to hot-rodded Marshall. Something amp-like and good sounding no matter where the gain knob is set. Just a good tone.
