London Underground

X Series Available!

The London Underground is based on the preamp of the legendary Orange AD200B.

Controls: Gain, Master, Bass, Mids, Treble
 

The Standard London Underground uses a NOS Soviet 6N21B submini tube in place of the 12AX7, allowing it to fit in a nice small box.

It takes a standard 9V input, and can accept center negative or center positive inputs. It uses internal regulators to supply 6V to the tube heaters and 200V to the plates, giving it the richness you expect from a full high-voltage preamp.

CURRENT DRAW NOTE: Like many Sushi Box pedals, this one uses a tube, which means current draw is a bit higher than a standard pedal. During warm up it will pull around 620mA on a 9V input, and when it has finished warming up it will pull about 470mA on a 9V input.
