Building pi-Stomp

Super detailed step-by-step instructions with high-res photos along with customization guides are provided online via Wiki

Enclosures are available for a common configuration and the Wiki has detailed CAD drawings for helping you design your own

The many ways of controlling pi-Stomp with sample performance.  pi-Stomp v1 is used but Core (v2) works similarly.

Over 100 pi-Stomp kits have been built in 18+ countries

Some user comments:

JK – “Instructions are clear, precise and well documented so I had no problem assembling everything.”

Tim – “Built this pi-stomp and enjoyed every minute of it.”

Chad – “Had such a fun time doing it! I found the instructions super super detailed and had no real issues”

Brent – “Hooked up to my guitar and amp and was blown away by the sound!!  When you select the different different Plug-In names you really get that sound style”

ZM – “…The end result is super fun and I still yet have to wrap my brain around all the amazing sonic opportunities this little box provides! I used it with my guitar and bass, but also my midi controller keyboard to create synth patches and effects. Amazing! It’s way better than any commercial pedal of this kind as well, if you ask me – since none of the commercial ones offer this much hackability!”
