Barn Owl PCBs are sold out. I am currently working on a V2 (with some improvements to expression pedal response) and hope to have them available sometime early 2027.

I love the online DIY community and am happy to offer my designs and PCBs for other builders. Fill out the form below and I will get back to you to confirm availability and shipping costs (shipping is typically $2-3 in USA and $3-6 international).

  • Dual Resonant Filter based on the Korg MS-20 Synth. Separate high pass and low pass filters in series with independent cutoff frequency and resonance controls for each filter and a master volume for the pedal. Includes expression control over cutoff with independent depth and direction controls for each filter.

    This PCB is sized for a 1590BBS / 125BB enclosure.

  • Get ready to get loud. BlackBender combines a Tone Bender MkII with the legendary HM-2 EQ controls; a toggle switch allows you to select whether the mids are linked to the high EQ or separately tuned. Boards use ECBE pinout for compatibility with any NPN transistors.

  • This clone of the short-lived Boss XT-2 includes switchable mods to the Contour control.

    This PCB is sized for a 125B enclosure.

  • One-knob fuzz with a twist: rather than adjusting the circuit itself, the knob on this guy is a blend control mixing between two different fuzzes. On the left side you have a thick, full range fuzz; all the way right is a tighter, more focused and searing lead sound.

    This PCB is 2.25" (5.7cm) square and will fit a 125B enclosure.

  • A classic, no nonsense fuzz circuit in a few different varieties and sizes. NPN/Sziklai boards can be used for the standard 2-transistor NPN configuration or in a Sziklai configuration using two NPN/PNP pairs (four transistors total). PNP boards use a 7660S charge inverter for safe daisy chaining. All boards offer ECBE pinout for compatibility with any transistors.

    These PCBs will fit 1590A or 125B enclosures as indicated.

  • DOD Phasor 201 surrounded by a pair of Overdrive/Preamp 250s. All circuits include mod switching.
