PROJECT SUMMARY A bass fuzz with two distinct voicings that can be blended together in any ratio, from vintage warmth to searing, gated chaos. Actual size is 2.3” x 2.42” (main board) and 1.78” x 0.86” (bypass board). BINARY DUAL FUZZ...
The Binary is a direct clone of the Duality based on our own trace, which is documented at length in our tracing journal. Some extra power filtering has been added, but otherwise everything is true to the original.

BUILD NOTES Filter and Blend knob rotation The Filter and Blend controls were inadvertently reversed in the original run of the Binary. This was fixed in version 1.1 which began shipping in January 2022. If your PCB does not say “v1.1” in the upper right then you have the earlier reversed version. In this version the blend knob goes from full effect at CCW to full clean at CW, and the filter control will act as a treble cut as you turn it up rather than adding treble as in a normal tone control.
Added build note about Blend and Filter controls being reversed from the original unit and how to change it. This will be corrected in version 1.1 of the PCB. 1.0.1 (2021-11-15) Corrected value of C18 (was listed as 68pF) and added build notes on midrange mod. 1.0.0 (2021-11-12) Initial release.
