Champion Leccy is a one-person DIY effects pedal operation run by a builder known as Woolly, based in Philadelphia after stints in North Tyneside, England, and Beijing. The brand designs and hand-builds analogue stompboxes with a focus on lo-fi, modulated, and unpredictable sounds, paired with distinctive hand-drawn artwork on each enclosure.

The lineup leans into experimental textures rather than traditional voicings. Pedals like the Skitter combine reverb and tremolo with broad modulation range, while the Woozy stacks tremolo, vibrato, chorus, delay, and reverb into a single lo-fi modulation box. Other releases include the Swan Hunter lo-fi echo and reverb, the Kitler tremolo and harmonic generator, the Dunsh fuzz with onboard EQ, and the Evil Twin.

Alongside the product line, Champion Leccy maintains an educational blog covering breadboarding, PCB design, and pedal troubleshooting, reflecting its roots in DIY electronics. Pedals are sold direct through the brand's site and through select retailers including Russo Music, Perfect Circuit, and Break The Machine.

Champion Leccy has 9 products cataloged on Equipboard, including Multi Effects Pedals, Fuzz Effects Pedals, and Overdrive Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Mdou Moctar.
