Psionic Audio is a Memphis, TN shop run by Lyle Caldwell, a boutique electronics builder and amplifier technician with deep roots in professional audio. Originally known for handcrafting a well-regarded lineup of effects pedals — including the Triad, the Telos, the 3.14, and the Lumos — Psionic Audio has shifted its focus to amplifier repair, restoration, and custom amp building. Caldwell brings the same precision and attention to detail that went into his boutique pedal designs to his amplifier work, making him a trusted resource for musicians who need serious tube amp repair and electronics troubleshooting done right.

Psionic Audio is a Gibson Authorized Service Center, meaning Gibson owners can bring their instruments and amps in with confidence that the work meets manufacturer standards.

Caldwell also shares his technical knowledge through an active YouTube presence, giving musicians an inside look at the repair and restoration process. For Memphis-area guitarists seeking quality amplifier repair or guitar electronics work from an experienced tech, Psionic Audio is a well-established name.
