Clone of Mutable Instruments Ears: a contact mic under the panel with ridges you can scrape, plus amplification and an envelope follower for external mics and instruments. Kit has SMD pre-soldered, about an hour of through-hole work (pots, jacks, LEDs, piezo), or assembled. Build guide provided. HP matches the original panel. Around 65 to 75 USD.
