Finally found a great clean sound in a small package - the Zvex Nano. Even though it's designed primarily as a 1-watt distortion amp, the clean sound is IMO, amazing (tight, focused, complex) Any suggestions on how to modify it so it can be used to drive a power amp (as a preamp)? Best if I can avoid a physically large power attenuator. The Nano is being planned for a small, atache sized rig, so size is important. I got an unclear message from a Zvex employee that there's a "supersonic" emission coming from the Nano, which would make it dangerous to use as a preamp. Anyone know more about this? Many thanks!
