Circuit-bending rock band CMKT 4 will be in town for a workshop on contact mics. They manufacture and sell bottle cap contact mics and plan to show how they do it. Bring cash if you want to purchase materials.
From CMKT 4:
We are circuit-bending rock band CMKT 4. We manufacture and sell bottle cap contact mics. We teach workshops about the process we use to make our microphones.
We price the workshops at $15 per person, which includes materials and instruction. Additional DIY kits are available at $10 apiece. We'll also have finished mics for sale. We encourage people to bring instruments to which to add a piezo pickup or they can make a stand-alone model for use on various instruments.
