![]() Note that the 'vibrato' circuit is actually a 'tremolo' effect in that it modulates amplitude not pitch of the signal. The single 12AT7 was used for the reverb driver while the 12AX7 was used for the vibrato circuit. The first two 7025 valves are used for the first stage pre-amps (one 'normal' channel and one 'vibrato'), the second 7025 being used for the reverb recovery and mixing stages. There are several versions of the Bandmaster Reverb circuit:īandmaster Reverb Valve / Tube Compliments ![]() On top of this it deviates from the traditional Bandmaster reverb formula in its use of a hybrid preamp section which utilises 12ax7 tube power alongside a DSP section. The Tweed Deluxe Speed Shop builds the finest Fender Tweed-era guitar amplifiers utilizing only the highest-quality new components as well as Speed Shop reverse-engineered TD58OT and TC58OT output transformers, A12Q and A10Q vintage AlNiCo speaker recreations, NOS (New Old Stock) resistors, capacitors, sockets, hardware - and vintage NOS tubes. The 'Custom' section keeps things no frills with Volume, Treble, and Bass knobs. It is however largely a different amp as it models the blackface variants of the Bandmaster and adds reverb. The 68 Custom Deluxe Reverb is a true 2-channel amplifier, with 'Custom' and 'Vintage.' Each section has two 1/4-inch inputs that can be used individually or in tandem, giving you a total of FOUR inputs on a single amplifier. It was made March of 1965 according to the OC date stamp on the sticker. This amplifier includes all Fender covers for the head and cabinet. On my pre-CBS Blackface Deluxe, the tube chart sticker says the circuit is AB763. The amp was reissued in 2009 as the Band-Master VM (Vintage Modified series), and features many of the characteristics of the original.

Power was increased from 40 to 70 watts/ RMS Line Out jack, hum balance pot and an ultra linear output transformer were added in 1977. Master volume models with "pull boost" tone circuit, a Mid control knob for the Normal channel and a tailless amp decal were introduced in 1976. Some later Bandmaster Reverbs also added a 3-band EQ on the Normal channel and a bright switch but this was uncommon across all models. This was complemented by the added functionality of a master volume and a push/pull boost. These changes increased the headroom of the amp and brought it more inline with the non-reverb versions. The output transformer was connected as ultra linear to the power tubes and larger filter caps where used. These series amps offer the designations AA768, AA568, AA1069 and TFL5005.Ī revised model was introduced in 1977 that increased power output to 70 watts. The revised circuit also places the gain stage within the reverb recovery circuit which causes the amp to break up earlier. Within a year the Bandmaster evolved into the Blonde piggyback head and 2×12 cabinet. The series included the Bandmaster, Concert, Super, and Vibrosonic. This resulted in the Bandmaster Reverb having reduced power over the standard model and increased sag and power amp break up. Comments: Part of quintet of amps that Fender called the Professional Amplifiers. Fender introduced the amplifier with a 5U4GB rectifier tube rather than the diode rectifier found in the previous Blackface Bandmaster.
