The API TranZformer LX is a bass effects pedal from API: Automated Processes, Inc., the pro audio company best known for its consoles and outboard studio gear. It takes the circuit of the API 525, a feedback-type compressor, and adds a 3-band EQ, all built into a stompbox format aimed at bass players1.
What it does
As a compressor, the pedal uses the same feedback-type design as API's 525 studio unit, a circuit style in which the side chain listens to the output of the compressor rather than its input. API describes the pedal as combining that 525 compressor with a 3-band EQ "incorporated in a versatile bass effects pedal"1. For a bass player, that means level control and tone shaping in one box, built around a circuit that comes from API's studio line rather than from a guitar pedal design.
If you are new to compression, the Compressor Pedals page explains the effect type and how the different circuit designs compare.
