If you can find one of these amps in your local guitar shop - or even the pawn shop- I sugest you pick it up. This solid- state amp has more than enough power to compete in any band situation. It's EQ can create any tone with minimal distortion. One drawback is that it's kind of heavy buy hey, it's from the 70's right? This is one of the most reliable amps I've ever used. Mine has survived numerous tours and insane,stagediving drunks. Most guitar shops have easy access to cheap replacement parts if and when it breaks down. I run mine through an old SUNN 2 X 15" cabinet (upgraded with JBL 15s) and can compete with Marshall full-stacks.

(editor's note -- some folks dispute the fact that the 470 is a 300 watt amp. the author assures me that the amp is marked at 300W@4ohm.)
