A toggle switch mounted on the back of the amplifier chassis allows switching between tube (the original) and solid-state rectification in the latter mode, output is boosted to 50 watts. The Vibroverbs used by Vaughan were also modified by Cesar Diaz in a number of ways:
#BANDMASTER REVERB SERIAL#
Vaughan acquired two 1964 blackface Vibroverbs in the late 1970s or early 1980s at two different times and locations, thought to have sequential serial numbers, but were sequential production numbers (#5 and #6). Production on the blackface Vibroverb was discontinued in late 1964.ĭue to low production numbers and their use by Stevie Ray Vaughan, 1964 (blackface) Vibroverbs have become highly collectable. Jensen speakers were used, with JBL available as an extra cost option. Gone also were the two ten-inch Oxford speakers in their place was a single fifteen-inch speaker. Still rated at 40 watts, the new design possessed the new blackface "optical coupler" vibrato circuit (in place of the tweed-style vibrato found in its immediate predecessor), and a bright switch. The Vibroverb, likewise, was given the new blackface cosmetics and somewhat different circuitry (AA763). The Twin was given two twelve-inch speakers and reverb it became the legendary blackface Twin Reverb. The Super had two additional ten-inch speakers and a reverb circuit added it became the much-sought-after blackface Super Reverb. Several models were introduced or greatly modified from their previous incarnation. This is from Wikipedia - so take it with a grain of salt: ( ) Switch To blackface, black Tolex-the 1964 Vibroverbįender revamped their entire amplifier line in the fall of 1963. I have a 15" bass cab with a neo in it but have never run that.

I've never run it through a 15, or 10s for that matter, but I have used 1x12, 2x12 and 4x12. I wonder about that a little - not from experience though - so this is simply to further the discussion and not to dispute your take on it.Įvery time I get my Bandmaster Reverb serviced (not very often) the amp Tech I use suggests converting it into a 1x15 combo BF Vibroverb (Vibroclone).
