Great amps! I like them both a lot, but I can't justify keeping them around. Both work perfectly, and look darned good. Prices are PayPal'd and shipped FedEx Ground CONUS.
Genz-Benz GBE 600 SOLD $400
Such a versatile amp - this one has a nice old Mullard 12Ax7 in it, too.
Mesa M3 SOLD $450
Loud as heck, and runs much cooler than the bigger M's. Great gigging amp.
