Building pi-Stomp
Super detailed step-by-step instructions with high-res photos along with customization guides are provided online via Wiki
An 11 minute overview showing what it is, what it can do, how it’s built and how to create and use virtual pedalboards Video shows pi-Stomp Core v2.0 prototype. v3.0 has all that plus a whole lot more!
The many ways of controlling pi-Stomp with sample performance. pi-Stomp v1 is used here but v3 works similarly.
pi-Stomp kits have been built in over 20 countries (yes, even Greenland!)
Some user comments:
JK – “Instructions are clear, precise and well documented so I had no problem assembling everything.”
Pat – “Hey, love my Pi-Stomp! I gig out regularly annd practice every week and it’s held up well. In fact, it has replaced nearly all my other pedals (except the synths).
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!”
Darren – “pi Stomp is an amazing project, I can’t believe the quality and completeness. Incredible value for the scope of the project, and the documentation and product quality is amazing.”
