DIY – Euro Rack Madness at Small Bear Electronics – Waltham, MA
Don’t miss this upcoming event in Waltham, MA. Happening on Sunday, December 21, 2025 at Small Bear Electronics. Doors open at 10:00 AM.
Euro Rack Madness
Choose one from these two Euro Rack modules:
DIY Analog Tank Reverb — OR — PG-13 Passive Gates
The Cram Audio DIY Tank Reverb is an analog circuit that uses an actual spring reverb tank to gives you a lush reverb effect. The module offers control for Mix and Feedback allowing you to tailor the reverb from subtle to overdriven, with many interesting settings along the way, helping you to craft the unique tone required to set your composition apart from the crowd.
The Cram Audio DIY Tank Reverb drives the reverb tank via discrete transistors to ensure rich clean reverb tone. The Mix potentiometer helps you to proportion the wet & dry signals and the feedback potentiometer helps to extend the natural decay of the reverb tank – almost to infinity if desired.
Build your own reverb module. Learn and save. You will solder, assemble components, and customize your very own musical instrument. This is our most advanced DIY so far, but no prior experience soldering is necessary – bring your creativity and enthusiasm to learn more about effect pedals! Don’t miss this opportunity to dive deep into the world of DIY electronics and create a unique and sophisticated effect pedal.
The – project is EuroRack compliant module. You’ll build a endlessly useful, passive dual gate with a tone control. Feed it a signal and use CV to control its amplitude!
If you need help with your circuit, your instructors have 20+ years’ experience building, designing, and troubleshooting analog and digital circuitry. So rest assured that we will get your effect working and get you jamming. Expect this workshop to last 3 – 4 hours. You’ll leave with a working module and a good handful of electronics knowledge. I hope to see you there!
