The Jake's Custom Shop Synchronizing Delay eurorack module is a sonic powerhouse that will take your modular synth to the next level. Create everything from subtle echoes to mind-bending washes of sound.  Using the classic PT2399 integrated circuit and an AtMega328 embedded system this module goes far beyond what any other standard delay will do.


Control Feedback, Delay time, and Wet/Dry mix with dedicated potentiometers to create an endless variety of sounds. Where this module really shines is its ability to sync delay time with an external clock signal.  This allows you to vary the delay in sync with your rhythm, a unique feature.  No musical instrument, let alone an analog synthesizer, is complete without a bit of delay to create a truly massive sound.
