February 2021 new releases: 8 new projects (including a brand-new trace!)

Today we’ve got eight new projects for you to check out. The first four are rounding out our Catalinbread series of projects, including a brand-new trace of the Karma Suture (both silicon and germanium versions). Only a few more Catalinbread circuits left to tackle now!

There are also a few other stragglers: the Harmonic Percolator (which the Karma Suture was based on), a pair of Silicon Tone Bender variants, and a Yamaha overdrive from the ’80s.

Calliope Vintage Fuzz PCBCalliope – Catalinbread Karma Suture

An adaptation of the Interfax Harmonic Percolator, with additional controls for diode clipping and pregain bass. Silicon and germanium versions are both supported.

Naos Classic Overdrive PCBNaos – Yamaha OD-10MII Overdrive

A simple yet effective drive circuit that combines a Tube Screamer-style clipping section with a Big Muff-style tone control, it’s more transparent than a Tube Screamer with less of a midrange emphasis.
