Description

The Keeley DynaTrem Dynamic Tremolo stands as a beacon of innovation in the vast sea of guitar pedals, offering an interactive playing experience that's as unique as your own musical voice. Unlike traditional tremolos, the DynaTrem responds dynamically to your touch, with the Rate and Depth of the effect modulating based on how hard or soft you play. This intuitive interaction opens up new avenues of expression, allowing the pedal to become an extension of your musical intention, rather than just another effect.

Crafted with the discerning guitarist in mind, the Keeley DynaTrem features a visually striking design that harkens back to the golden age of tube amps and radios, ensuring it looks just as good as it sounds. With three distinct modes - Dynamic Rate, Dynamic Depth, and the soulful Harmonic Tremolo + Reverb Mode - this pedal invites you to explore a landscape of tonal possibilities. Whether you're gently caressing the strings for a subtle pulse or attacking with vigor for a deep, throbbing effect, the DynaTrem adapts to your playstyle.

The inclusion of a Wave Table with four selectable waveforms further enhances the pedal's versatility, allowing for precise sculpting of the tremolo effect. From the smooth rise of a Ramp Up to the angular chop of a Square Wave, each setting offers a distinct flavor to inspire new creative directions. True to Keeley's reputation for quality, the DynaTrem also boasts features like integrated noise reduction and true-bypass switching, ensuring your tone remains pristine and unaffected when the pedal is disengaged.

Key Features:

  • Dynamic Rate and Depth controls adapt to playing intensity for expressive tremolo effects
  • Three modes: Dynamic Rate, Dynamic Depth, and Harmonic Tremolo + Reverb Mode for versatile sound shaping
  • Wave Table with four waveforms: Ramp Up, Sine Wave, Ramp Down, and Square Wave
  • Integrated noise reduction for the quietest possible operation
  • Output Volume Control for boosted effect presence
  • True-Bypass switching preserves tone when the pedal is off
  • Compatible with any standard 9 volt, negative tip power supply

"There are certain sounds that I love. I use a GigRig G2 at the front end normally when I’m writing and recording, and I’ve got a selection of stompboxes at the front end, like a Prince of Tone or King of Tone, Jester Overdrive, Analog Man Mini-Chorus, Keeley tremolo, and an Electro-Harmonix POG and Pitch Fork."
