Re-posted for price drop to $300. I'll also ship it if you want to pay for packing and shipping.
For those not in the know, it's a mono block (one channel, not stereo) power amp only. No preamp. You need a SABDDI or BassBone or something to drive it. I've driven it with my new Eden WTDI, and I will testify that it sounds just bitchen. It'll power four 8-ohm cabs or two 4-ohm. It has minor rack rash on top, but the face is like new, and it functions as new. It has a slight power-on transient which Fender says is normal for this amp.
I'm the original owner, and I've never even gigged it.
Here's a link to the unit at GC. Notice its thousand buckness.
