The Super Stack is a tube boost with a Fender tone stack EQ. The new production JJ 12AX7 tube is powered by an internal high voltage charge pump, giving the same gain and response as that found in many classic amps.


The EQ is an exact recreation of the Fender tone stack with Mids. It is also the same as the Alembic F2B.


The pedal requires a 12V DC power supply for maximum performance. The pedal can be powered by a 9V supply, but the gain and headroom will be decreased. Do not use a supply greater than 12V or less than 9V. The supply must be capable of providing at least 300 mA, and must be regulated. The supply must use a 2.1mm barrel with center negative polarity.


The Super Stack has a true bypass switch.


Dimensions: 4.77" long x 2.6" wide
