The appropriately named Keeley DynaTrem gives you a full, dynamic tremolo that responds directly to your playing. Express yourself unfettered using the Rate and Depth controls to adjust the pedal's sensitivity. The DynaTrem's three modes are Dynamic Rate, Dynamic Depth, and Harmonic Tremolo + Reverb, the last of which creates soulful phase-like vibes. You can even choose one of four wave-forms with the Shape knob for total control over your sonic palette!
