ACME Audio MTP-66 Motown Tube Preamp Shop all ACME Audio

The MTP-66 Motown Tube Preamp is inspired by the original 1966 "Motown Guitar Amp" which was a 5 channel input box created to record multiple guitar and bass instruments at once. Many iconic performances from the classic Detroit label were captured using this unit, including the James Jamerson distinct bass tone.

With Acme Audio Manufacturing’s line of faithful recreations of legendary Motown gear, comes this single-channel lunchbox preamp that has been exactingly reborn using the original 1966 engineering schematics, and features an all-tube signal path, with hand selected tubes that drive a Cinamag output transformer. Besides being an instrument-to-line-level all-tube preamp, Acme Audio has added a microphone amp section that is also based on Motown Engineering’s original designs, featuring a fixed gain pentode with the Acme Audio/Triad input transformer. Other key features include adjustable input and output controls (not made available on the original,) giving you the ability to adjust your sound to the desired amount of drive and compression.
