The Carl Martin Surf Trem delivers a classic tremolo sound inspired by vintage tube amplifiers from the 50s and 60s. It provides smooth, musical modulation that ranges easily from a subtle, atmospheric movement to a deep, pulsing tremolo. Designed with a stripped-down, pedalboard-friendly layout to eliminate unnecessary complexity, it features just two straightforward controls: Speed for modulation rate and Depth for effect intensity. The pedal is built for reliable use on stage and in the studio, housed in a rugged die-cast enclosure.

When Carl Martin refreshed their Vintage Series, the goal was to make the pedals more pedalboard-friendly without changing what made them sound right in the first place. Surf Trem is Carls take on classic tremolo, built around the same core trem circuit we developed for the CM Tremovibe — but stripped down to the essentials.

The Carl Martin design team voiced the Surf Trem to capture the unmistakable tremolo character of classic tube amps from the 50s and 60s. The modulation is smooth, musical, and immediately familiar, whether you’re after subtle movement or deep, pulsing tremolo that defines the rhythm.

The control layout reflects that simplicity. Speed sets the rate of the modulation, while Depth controls how pronounced the effect becomes. Just like on a vintage amp, everything happens right under your fingers — no extra modes, no secondary layers.

Surf Trem is built in a rugged die-cast enclosure with a compact footprint, designed to handle real-world use on stage and in the studio. It’s a straightforward tremolo pedal that focuses on feel, timing, and musical response rather than complexity.
