The Crate Powerblock is now on sale everywhere for $99. This is an incredible little amp for the $189 I paid a year ago, let alone for $99. About the size of a couple of VHS tapes, 75w stereo, 150w mono, actually sounds good. Add a nanoverb in the effects loop, stick a sans-amp in front and it's damn good. The perfect backup amp. Small and light, but can get you through the gig if your rig fries. Definitely worth checking out.
