Ernie Ball P06188 Expression Series Tremolo Pedal Standard
The Ernie Ball Expression Tremolo packs a lot of controls into its compact chassis. Individual Depth and Rate knobs give you acute control over the tremolo effect. The Waveshape control supplies you with five different tremolo waveforms: Slow Rise, Slow Fall, Sine, Square, and Harmonic. The Reverb knob dials in everything from subtle room ambience to lush soundscapes. And most prominently, the foot-sweepable treadle gives you control over the tremolo's depth, rate, or both simultaneously.
