Many of your favorite pedals have nearly identical circuitry, with the only important difference being the patches running on their FV-1 audio DSPs (digital signal processors). We're not talking about cheap multi-effects units, but some of the most popular, high-end pedals out there (EQD, EHX, Walrus, Chase Bliss, and tons more).
Pedal companies obviously want you to buy multiple pedals, each running only a single patch. This creates a neat little niche in the market for something like this.
Mimir's Well is a very limited batch of expertly handcrafted pedals. It uses all of its hardware to run a single patch at a time, like your other favorite pedals that use the FV-1 (e.g. Dispatch Master, Rainbow Machine, Arp 87). Unlike those, though, it also holds 23 patches you can switch between. You customize your pedal by choosing from 163+ patches designed by amazing audio engineers and enthusastic members of the DIY pedal community.
