The API TranZformer series, introduced in the 2010s, consists of high-quality analogue pedals by Automated Processes, Inc. (API), a company known for its professional-grade audio equipment. The TranZformer series includes the TranZformer LX for bass and the TranZformer GT for guitar. These pedals incorporate API’s renowned analogue circuitry, traditionally found in high-end studio equipment, into compact pedals designed to enhance and shape tone in both live and studio environments.

Each TranZformer pedal includes API’s 3-band EQ and compression, allowing musicians to apply studio-grade sound shaping directly to their instruments. The EQ section offers precise tonal adjustments, while the compressor provides smooth dynamics control without losing clarity or punch. Built with API’s signature components, including custom transformers, these pedals offer a warm, dynamic, and professional-grade tone. Ideal for musicians seeking studio-quality sound on stage or in the studio, the TranZformer series reflects API’s legacy of exceptional audio engineering and robust construction.
