LongShot 5 is an open-source printed circuit board by FandSonthesizer, from the FandSonthesizer/LongShot_Delay repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 83.1 × 85.1 mm with 115 parts on 87 nets, routed with 1,732 tracks and 80 vias.
It is built around the PT2399. Its parts include 54 resistors, 35 capacitors, 8 connectors, 7 transistors and 5 ICs.
This is the evolution of our wire-head delay pedal. Here we add a wobble effect top simulate a worn tape drive, where the motors and belts are quite old.

It measures 83.1 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
115 parts, built around the PT2399. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the FandSonthesizer/LongShot_Delay repository on GitHub, at the commit this page was made from: the board is LongShot_5/LongShot_5.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
