All Gretsch amps were built by Valco through '68. Valco amps have a sound of their own - it's raw and warm, with a lot of midrange growl

2-channel 40W 2x12" vintage Combo amp made by Valco in Chicago in the mid-60s
Excellent Condition musically and cosmetically, clean inside and out, (Please see photos). Two discrete channels ("Bass" & "Guitar") each with High & Low inputs and independent Volume & Treble controls. Guitar/Accordion channel has excellent bias tremolo with Speed & Depth controls. RCA Black Plate tubes 2x6L6GC power tubes & 4x12AX7

Good condition all around with some wear on the grill cloth, original tolex in excellent condition, some face plate wear near Bass Input, one nob has been replaced and one metal foot is missing. Very clean round sound without muddiness or ice-pick top end, gets girthy and overdriven at close to full volume.
Jensen C12N speakers in great condition produce a classic American sound perfect for many types of music from roots to blues, rock and jazz. Sounds very lively at modest volumes and really roars when cranked.
Original vinyl cabinet covering in nearly perfect shape,  sparkly dark-color grill intact with only slight discoloration and a few wear spots.

33" tall X 24" wide x 10" depth, about 51 lbs. Perfect size for portability yet loud enough for most indoor gigs.
