delyk PCBs is a one-person DIY guitar pedal PCB operation based in Anna, Texas, just north of Dallas. Founded by Kyle in 2015 after he began etching his own boards in 2013, the shop grew out of his Effects Tester design — a utility board meant to help troubleshoot circuits without enclosures. The company focuses on printed circuit boards for hobbyist pedal builders rather than finished pedals.

The catalog spans overdrive and distortion, boost, fuzz, delay, modulation, and utility layouts, along with small- and mini-format boards for compact enclosures. Specific products include the "Up, Down, Daddy!" PCB and the 3PDT v2 switching board, alongside clearance items and parts. Kyle is also an admin of the DIY Stompboxes Facebook community and openly points builders toward other PCB vendors such as Aion FX, madbeanpedals, PedalPCB, and Fuzz Dog.

Delyk PCBs has 1 product cataloged on Equipboard, including Chorus Effects Pedals.
