The Kingsley Constable is a tube guitar preamplifier modeled after the classic "plexi" design of the late 1960'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 plexi tones are achieved by using one of the above methods, the Constable 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. The Kingsley Constable uses two 12ax7 tubes running at high voltage (around 270VDC) to get the most authentic valve tone out of its hand wired circuit.
