Product description "TouellSkouarn - Mar Karit"
Mar Karit is an all-tube pedal preamplifier inspired by designs of the 1950s.
It contains 2 tubes, one NOS EF86 for the preamp section and one 6J1P (6ak5) for the buffer output. It is an all-tube Preamp running on a 9V power supply (center positive) and operates at 35volts internally.
The Mar Karit produces a warm, rich, and full-bodied sound, and can capture both the softest and loudest sounds with great accuracy and clarity. Pushed a little too far it can produce pleasing harmonic distortions and warm saturations. The two volume knobs control the level of each stage.
Power supply not included. 9V center POSITIVE, min. 400mA required.
