Surfy Industries SurfyTrem V1.1 Tremolo Pedal - Blue

The Surfy Industries SurfyTrem V1.1 tremolo effects pedal gives guitarists direct access to the lush, pulsing tremolo tones of classic American tube amps from the early '60s. Designed to replicate the revered vibrato channel found in vintage brownface and blackface amplifiers, this all-analog pedal delivers two distinct tremolo voices in one compact unit. Whether you're chasing syrupy harmonic pulses or hard-edged stutter, the SurfyTrem provides the kind of movement and musicality that made those original circuits a defining part of surf, soul, blues and early rock guitar tones.

Brownface Mode: Rich, Harmonic Modulation

In brownface mode, the SurfyTrem delivers deep, swirling harmonic tremolo reminiscent of early-60s American amps. This waveform gently shifts highs and lows independently, creating a movement that's often compared to a rotary speaker—sweet, fluid and intensely musical. Unlike more aggressive on/off styles, this tremolo breathes with your playing. Pick softly and the modulation swells with rich depth; dig in, and the effect subtly tucks behind your attack, preserving clarity and articulation. It's this dynamic response that has made brownface-style tremolo a secret weapon for expressive players. Whether you're crafting haunting ambient textures or vintage-soul grooves, this mode rewards nuance and phrasing.

Blackface Mode: Punchy, Percussive Pulse

Switching to blackface mode transforms the SurfyTrem into a classic amplitude-modulation unit. Here, the volume is modulated in a bold, rhythmic manner—producing a more pronounced, stuttering effect that's ideal for cutting through a mix. It doesn't track your dynamics the way harmonic tremolo does, but that's the point: This style shines when you want bold pulses and clear separation, especially during solos or syncopated rhythm parts. With its brighter voice and consistent waveform, blackface mode offers an unmistakable tremolo sound that defined countless recordings from the mid-60s onward. It's a more assertive character that adds space and swagger without getting lost in the mix.

Simple Analog Controls for Deep Tone Shaping

The SurfyTrem keeps it classic with just three controls: intensity, speed and a toggle switch to move between brownface and blackface modes. The streamlined layout makes dialing in period-correct textures effortless. The speed control ranges from a slow shimmer to a rapid warble, while the intensity control lets you blend subtle movement or full-on modulation. Crucially, the circuit isn't true bypass—and that's by design. Just like the amps that inspired it, the SurfyTrem slightly darkens the dry signal and imparts a hint of analog warmth even when disengaged. That always-on coloration contributes to its overall authenticity and helps it sit naturally within a vintage-style signal chain.

Vintage Feel, Modern Stompbox Convenience

Though it evokes the feel of vintage tube gear, the SurfyTrem is built for real-world pedalboards. It operates on standard 9V DC power or a 9V battery and features standard 1/4" input and output jacks. The analog circuitry is housed in a compact, rugged enclosure that easily fits into your pedalboard setup. And while its tone is pure throwback, the build quality and reliability are thoroughly modern. Whether you're after the subtle flutter of old-school surf, the warble of swampy ballads or the chop of psychedelic breakdowns, the SurfyTrem delivers tube-style tremolo flavor without the amp.

Bring Iconic Tremolo to Any Rig With the SurfyTrem

If you've long admired the warm, organic tremolo found in classic American tube amps but don't have the time or resources to chase down rare gear, the Surfy Industries SurfyTrem V1.1 tremolo effects pedal brings that magic into your pedalboard with stunning accuracy. With both harmonic and amplitude modulation on tap, you get two iconic textures in one unit—each deeply musical and responsive in its own way. It's easy to use, expertly voiced and true to the analog heritage of the tones it emulates. Whether you're a vintage purist or a modern player looking for expressive tremolo, the SurfyTrem is a compelling way to add movement and vibe to your sound.
