Combining a classic API 525 feedback-style compressor circuit with inductor-based 3-band EQ styled after the legendary API 553 program equalizer, the TranZformer series makes it easier than ever to sculpt your tone to perfection. The TranZformer pedals are housed in a robust, road-worthy casing fitted with balanced and unbalanced outputs. Other features include separate gain and level controls, individual footswitches for tone and compression activation, polarity invert switches on each output, a ground lift, clipping indicator, transformer output, and naturally, that classic API sound. Guitar and bass versions are available.
