The Keeley DynaTrem: Tremolo that plays you back

Dynamic tremolo that responds to your touch

The Keeley DynaTrem is a touch-sensitive tremolo that reacts to your playing in real time. Pick harder and the rate or depth increases. Ease off and it mellows out. With simple controls that dial in sensitivity, the DynaTrem becomes an extension of your dynamics, creating modulation that breathes with your performance.

Three expressive modes

Dynamic rate mode accelerates as your playing intensifies. Dynamic depth mode deepens with attack and lightens up when you relax. A third mode introduces lush harmonic tremolo with a built-in reverb, adjustable using the shape knob. The result is phaser-like movement that is smooth, soulful, and inspiring to play.

Custom waveforms and a hidden mode

The shape control selects from four waveforms: ramp up, sine, ramp down, and square. On units with serial numbers above 300, a hidden standard tremolo mode becomes available when shape is turned fully down in delta rate or depth modes, delivering a classic triangle wave response.

Studio quiet and stage ready

Noise reduction circuitry keeps the DynaTrem whisper quiet even during intense tremolo swells. The output volume control can add clean boost when needed, and true bypass ensures your tone remains untouched when the pedal is off. The enclosure features vintage inspired graphics that match the warm analog character of the sound.

Built for modern pedalboards

Power comes from a standard 9 volt center negative supply with a draw of 60mA or greater. No battery compartment, no nonsense—just expressive tremolo in a compact footprint.
