Here’s a vintage 1968 Fender Twin Reverb- Amp AB763 electric guitar amplifier. This factory JBL-loaded drip rail example, serial number A 14522, is in near mint 100% all original condition and includes the original hang tag, the original owner’s manual, and the original black dual-function VIB/REV footswitch! Famous for ushering in the SilverFace aesthetic with the identical schematic of the highly coveted AB763, this rare variety is one of best bang-for-your-buck vintage amplifiers available, as is the case with most drip rail/drip edge models. Appropriately considered the irrefutable king of clean, the Twin Reverb has always been synonymous with an overabundance of clean headroom with highly musical qualities. The same attributes that make the Twin Reverb notably perfect for surf-inspired pristine guitar tone, are the same that render it appropriate for use with pedal steel, effects pedals, and any other application whereby the most authentic signal path is desired. In fact, this amp was owned and used by Southern California pedal steel fixture, Blackie Taylor. Impressively not too harsh, nor hi-fi in character, the Twin Reverb is loud, dynamic, clean, robust, and perhaps offers the best examples of both the Reverb and Vibrato effects.
Serial Number: A 14522
Speaker Codes: 22950, 22958 (JBL D120F)
Transformer Codes: 606816, 606825, -606-7-40, -606-8-21
Factory Inspection Stamp: F053368 (on the chassis and matching JBL D120F speakers)
This particular variety is the rare drip-edge/drip-rail Twin Reverb with black vertical separation lines on the SilverFace control panel and black/blue striped grillcloth, the combination of which is specific to 1968 only. During this transitional period, from BlackFace into the SilverFace control panel cosmetic, these amps were still built with BlackFace era components and schematic designs, making this example just as great sounding as any early ’60s blackface Twin Reverb. This is also the first year that Fender amps were factory equipped with a grillcloth badge advertising the upgraded JBL speakers.
This ’68 Fender Twin Reverb features: (4) 6L6, (3) 7025, (2) 12AT7, and (1) 12AX7 original tubes (GE, RCA, and Telefunken) through the original matching 2 x 12″ JBL D120F signature speakers.
This amp was in storage for many years, so I brought it up slowly on a Variac to reform the original caps. It is entirely 100% all original: every last cap, tube, resistor and screw, and I didn’t want trauma to compromise the originality. After letting the amp warm up for 30 minutes post Variac exercise, I played it for over an hour with not a single issue. It is very efficient, super loud, clean, sweet, and has the most lush reverb imaginable. The JBL D120F speakers both retain original cones, and both sound remarkable.
