This is a great sounding pre CBS Deluxe reverb!!! Just serviced by Andy Fuchs at Fuchs Audio Technology. Was worked on by amp legend Cesar Diaz in 1990 and his signature and date are on the inside of the chassis. This amp has a voltage regulator which means that this was an export model that could be used overseas as well. Has a brand new Celestial G12-H which sounds amazing!!! This amp is gig ready and has that warm, lush sound the pre CBS deluxe have!!!
