The Keeley Dynatrem is a boutique-style dynamic tremolo pedal that responds to your playing In other words, play it softly, and it relaxes, but play it harder and it's more responsive. This awesome pedal allows you to switch between three modes that allows the pedal to react differently as you play. These modes are as follows:
Dynamic Rate - the harder you play, the faster it modulates
Dynamic Depth - with gentle playing, this mode barely throbs. However, play it aggressively and you get a hard, deep pulse
Harmonic Tremolo & Reverb - a sweet, soulful, phase/vibe sound, with reverb levels changing as you adjust the 'Shape' control.
Once your Mode is set, you can then adjust the Shape control accordingly. This control pot gives you 4 wave forms to choose from: Ramp Up, Sine, Ramp Down, and Square. Whether you want your modulation effect to be smooth, wavy, or choppy, this control allows you to do it. In addition to this, if you turn the control all the way down, you get a standard Triangle wave tremolo, in the Dynamic Rate or Dynamic Depth modes. If your mode is set to Harmonic Trem, this control pot adjusts the level of Reverb in your mix rather than the wave shape.
