Black Eye II

Black Eye II is a medium-high gain preamp/distortion based on the Soldano Supercharger GTO. A few changes have been made, most notably that the single-knob tone control was swapped in favor of a Baxandall tonestack, and a Bass Boost switch was added. The bass boost isn’t a huge drastic change, but it opens up the low end frequency response to make the pedal more suitable for use on bass. With the gain all the way down you get an almost-clean light crunch, and fully dimed you can get monstrously aggressive, face-melting distortion.

The Summer 2024 revised edition of Black Eye II has the same great circuit as before, but now with upgrades like film capacitors in the audio path and soft-touch relay bypass switching.

As a tube pedal, Black Eye II requires a high amount of current to operate correctly. I recommend a 9-12VDC power supply capable of delivering at least 600mA. Using less than this can damage the power supply and/or the pedal.

Enclosure size: 4.7 in x 3.7 in x 1.34 in (119 mm x 94 mm x 34 mm)
