Internal voltage doubling circuitry is used to generate the large supply required by the JFET using only a 12V DC input.

A removable high impedance FET buffer is included to correct the output impedance of the preamp circuit. It can easily be bypassed using the low profile slide switch if desired.

Stock units are equipped with a logarithmic taper potentiometer. Linear taper pots are available on request, but will reduce the rotational range of level adjustment by approximately half.

The master stomp switch and output buffer slide switch are both wired for true bypass operation.

12-18 Volts DC 5.5x2.1 negative center barrel connector (Boss style) required for operation. No internal battery.

This effect can be used with Voodoo labs PP2+, BBE Supacharger and similar 9V DC supplies that offer a few older Boss ACA unregulated outputs (~16V). Plug # 5 or 6 (BBE and PP2+)must be used with the small slide switch set away from normal. Holes 1-4 are not able to maintain 12V and will normally drop to a ~10V output with the Badgerplex connected.

To avoid incurring an escalated price on all customers an AC adapter is normally excluded. Each unit will only ship with a 12V DC negative center output 120V AC adapter upon request.

Cast aluminum case measures 1.25" H x 2.39" W x 4.41" L (lid included in measurement)
