Independent shopping perspective
The Korena take
SurfyTrem Deluxe is an analog tremolo pedal with two switchable voices and flexible two-output routing. Brownface mode supplies harmonic tremolo, while blackface mode uses amplitude modulation for a more direct rhythmic pulse. Run the pedal as synchronized dual mono tremolo circuits or turn a mono signal into a stereo field. Speed, intensity, and level controls keep adjustment straightforward, while true bypass, quiet soft-touch switching, and a clickless brownface/blackface relay suit active pedalboard use.
Strong match
Who this is for
- Running synchronized tremolo through two amps or a stereo pedal chain.
- Switching between harmonic movement and pronounced amplitude pulses during a set.
- Converting a mono source into a wider stereo tremolo field.
Consider the trade-offs
When to look elsewhere
- Players who require a bundled pedalboard power supply; it is sold separately.
