Main Features
Three Reverb Algorithms
Hall: Emulates the vast, diffused sound of an acoustic hall with long decay times
Spring: Captures the classic bouncy twang of vintage spring reverbs
Plate: Produces smooth, dense, and focused analog plate reverb tones
Control Sliders
Decay: Adjusts the length of reverb tail from minimum to maximum
Feedback: Sets the amount of wet signal fed back into the effect
Mix: Blends the original clean signal with the reverberated sound
Trails Mode
Allows reverb tails to fade naturally when the pedal is bypassed, adding a more musical decay behaviour. Easily toggled on or off during power-up.
