Star ground system to reduce induced current chassis noise.
Normal (Type F) Bright (Type M) inputs with separate preamps and Gain controls for the unique smooth Fender 5F6
warm tones or the Marshall Plexi SLP great high mid tones....or you can use an AB-Y switch and create your own distinct
tones.
Classic 60's JTM45 - Bassman 5F6 style 3-BAND TONE STACK for extended flexibility in shaping your tone.
MASTER level control so you can crank the GAIN's up and overdrive the preamp without overdriving the output tubes.
Classic Type 5F6A Style Presence control .
Unique NNFB "Edge" switch on the PRESENCE control that transforms the power amp section into a No-Negative-
FeedBack style amp for more open, less compressed tones.
Classic 6L6's in the output in place of the original Deluxe 6V6's to give you more power and headroom. The bias is
optimized using FRENZEL Multi-Valve design which allows you to use octal based 6L6, 5881, KT66, KT88, 6550, or
EL34 tubes in the output stage without adjusting anything.
Preamp and driver tubes are 12AX7 EH's known for low noise and linearity. You may also use 12AT7's or 12AU7's for
different tones and overdrive.
Classic 60's style insertion type Serial Effects Loop with Return Jack (Power Amp In), Send Jack (Preamp Out), and
Send Level Control. (Please note this is not for pedals. Pedals are designed for use on the inputs of amps.They are the
wrong impedance and do not have the proper output voltage for driving a serial insertion type of effects loop. )
Dual Speaker Jacks
A Classic Hammond Hi-Fi output transformer for extended low frequency performance with 4 - 8 - 16 ohm outputs
selectable by a rotary switch.
Cathode / Fixed Bias Selector Switch - Allows you to choose cathode bias for the classic "compressed blues" sound, or
fixed bias for "dynamic rock" sounds.
Power Output: 40 watts RMS (25 Watt version also available)
5U4 rectifier, you can sub 5Y3, 5AR4, or Solid State Plug in for different amounts of sag.
Extra long (10') three prong grounded power cord.
STANDBY switch to turn off the plate voltage during warm-up.
Rock solid point-to-point hand wiring using only the best of parts...low noise tubular polypropylenes caps, metal film
resistors, ceramic sockets, switchcraft jacks...etc.
Sweet vintage clean to classic overdrive tones with three different types of distortion depending on whether you are
overdriving the preamp, output... or both!
Tube compliment: The amp comes with 3 - 12AX7, 2 - 6L6, 1 - 5U4, but you can substitute 12AT7's or 12AU7's in the
preamp and driver for different tones and overdrive sounds. You can also substitute 5881's, KT66's, KT88's, 6550's, or
EL34's in the output stage for different sounds.
