Power supply included.

The Constable Bassman uses two 12AX7 tubes running at high voltage (around 270VDC) to get the most authentic valve tone out of its hand wired circuit.

Overview

The Kingsley Constable Bassman is a tube guitar preamplifier modeled on the Fender Bassman of the late 1950's. It is designed to push a power amplifier directly but may also be used into the effects return of a guitar amplifier effects loop.
While the most authentic Bassman tones are achieved by using one of the above methods, the Constable Bassman also features a mode of operation that attenuates its output to allow it to be run into the front end of a guitar amplifier or in front of other guitar effects pedals, for a clean boost or mild to medium drive pedal.

Features

The full feature set of a Bassman preamplifer is provided, including controls for Volume 1, Volume 2, Treble, Middle and Bass. There are now two Master volumes - the front panel "Master" as well as a second Master volume on the back panel, which is activated by stepping on the left footswicth (labeled "M A/B").
This gives the ability to footswitch between two different output levels, which can be used for rhythm and lead volumes, or for two levels of drive when using the Constable Bassman to drive a power amp into overdrive.
The 3-way "Output" switch offers full output in position 3 (line level), attenuated output in position 2 (instrument level) and attenuated output with treble roll-off mode in position 1 (instrument level).
"Volume 1" is the brighter of the two volumes and "Volume 2" is darker with a full bass response.
"Volume 1" features a choice of two bright caps, selectable via the 3-way "Bright 1" switch.
Set to position 3 gives the classic tones of Bassman amps. Position 2 on the "Bright 1" switch reduces the bright cap for a more moderate brightness response.
