Blue Warbler 2
The Blue Warbler 2, perhaps the most anticipated JMK PCB ever! Undergoing the longest (by far) development period of any of our projects, is quite definitely a unique and very wonderful sounding...

The Modulay is a PT2399 delay in the classic style, meaning that it hails from the same data sheet setup as many other PT2399 delays – but with a pair of modifications. Along with the classic PT2399...
View ArticleLittle Angel
The Little Angel Chorus is a digital chorus designed around the PT2399 delay chip. As such, it’s much less expensive to build than the more common BBD based Analog Choruses, and is made from from more...
View ArticleParalyzer
The Paralyzer grew out of one of our other products, the Panner. The Paralyzer is a unique effect in that it’s really more of a utility device for putting a pair (or more) of effects in parallel with...

This limited edition Christmas Red PCB is a smaller, more condensed version of the Engineer’s Compressor. It utilizes a CA3080 chip in a fairly different configuration to give a much lower noise floor...
View ArticleLevel Up
The Level Up is a new type of circuit from JMK, and is based around an Octave type sound. The Level Up fits somewhere between an overdrive, a fuzz, and a boost pedal, with the unique ability to blend...
