The TC Electronic Ampworx V550 Preamp is a dual-channel guitar preamp pedal that faithfully recreates the tone and feel of a classic high-gain tube amplifier, most notably inspired by the iconic 5150 Mk1 sound. It features two independent channels with separate Gain, Volume, and EQ controls that let you dial in clean, crunchy rhythms or saturated lead tones. The pedal also includes a switchable boost, 3-band EQ, Reso and Presence controls, a Celestion 4×12® cab simulation, and dedicated DI and headphone outputs, making it suitable for pedalboard use, recording, and direct performance.
