Independent shopping perspective
The Korena take
Loma Prieta combines harmonic tremolo with four selectable wave shapes, so you can move from a smooth sine pulse to square or rising and falling ramp patterns. Its Shift footswitch puts Tap Tempo, Lo-Fi, Feedback Distortion, and Double-Time functions under momentary control. Use the Grit knob to add drive within the tremolo circuit, or connect an expression pedal to vary the rate. A top-side toggle changes between harmonic and standard tremolo modes, with the LED color showing the selection.
Strong match
Who this is for
- Building tempo-synced tremolo parts with momentary access to alternate Shift functions during a performance.
- Controlling tremolo speed from a standard expression pedal instead of relying only on the pedal controls.
