TRYM

Tremolo

The Aalberg TRYM Tremolo Pedal delivers everything from a hard-hitting square wave to a gentler sine wave shaped tremolo effect, with endless possibilities in between. With the Tap-tempo foot-switch you can change the tremolo speed, and by using stereo mode you can alternate the tremolo effect from left to right providing a spacious and mesmerizing tremolo effect.
