It looks nice, though in terms of practicality, it’s not exactly suited for foot stomping. It works well as a preamp for a cigar guitar, which in this case uses nothing more than a piezo element and needs a bit of a boost.
Tayda Electronics (where I get many of my parts) calls this their “Super Hard On” circuit. I used a loose tea canister for the case. My brother helped me with the drilling since he has access to better tools.
