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.
Mimir's Horn is the smaller, and more affordable version with the same great audioprocessing but simplified to omit the display and extra bank.
