FACTOIDS & TRIVIA

The Twin Reverb (Model AB763) was introduced in late 1963 as an upgrade to the blonde Twin Amp (Model 6G8-A). Like its predecessor, the Twin Reverb was an 80-watt, 2x12 combo amp with tremolo, but it also had on-board reverb. The extra gain stage and different preamp circuit gave the Twin Reverb a little more volume than the Twin Amp, too. The Twin Reverb is known for its clarity, headroom and volume, and has been favored by many guitarists seeking clean sound at high volumes. Telecaster players and steel guitar players especially seem to gravitate to Twin Reverbs. Fender offered JBL D-120F speakers as an option on the Twin Reverb and these speakers are preferred by many guitarists since they can better handle the power of the amp as well as providing better low and high end response. In late 1967, Fender changed the appearance of its amp line with a brushed aluminum control panel with blue graphics in place of the black painted panel with white graphics. The grill cloth was also changed from tan with silver thread to tan with blue thread with aluminum trim around the grill perimeter. Despite the cosmetic changes, the coveted "blackface"AB763 circuit remained in use until about May 1968. The amp shown here was made during the first few months of "silverface" production and has the AB763 circuit.
