Check out the NEW Specimen hand-wired Tweed Amps!

Since 1986 we have been creating custom instruments, amplifiers and horn speakers one at a time in our Chicago shop. Each Specimen is handmade using traditional techniques and innovative design.

We also provide expert repair service and teach classes in guitar building, guitar setup and repair, and tube amp building.
