Klinger Custom Pedals is a boutique effects builder based in Melbourne, Australia, run by musician and pedal maker Shaun Klinger. The workshop focuses on hand-wired fuzz circuits inspired by the classic mid-1960s British designs that shaped early heavy guitar tones, with builds often sourced around NOS germanium transistors such as OC75, OC76, and NKT275.

The catalog centers on fuzz variants including the MK1 Tone Bender, MK2 Pro Fuzz, Supa Fuzz, Buzz Fuzz, and Astron, along with modified Fuzz Face-style circuits. Pedals are built individually, with transistors auditioned and gain-matched per unit, and are sold direct through shaunklinger.com.au and through Reverb, with distribution in Japan handled via Montreux.
