MOD: Modulated chamber reverb. The Tweak knob controls the speed and depth of the pitch modulation.
SHIM: Reverb with a pitch-shift component. The Tweak knob controls the pitch shift interval, either an octave down or an octave up.
LOFI: Dirty and filtered reverberation, like the echo you might get out of a broken karaoke machine. Reverb and Space control the decay and pre-delay, respectively, while Tweak controls the amount of dirt and grit present in the reverb signal.
PLATE: Bright and present reverb based on both a mechanical plate design and the early electronic plate reverb algorithms. Tweak adjusts the high-frequency damping of the reverb signal.
SPRING: You know what this one is. Drippy and wet, this spring reverb simulation is great for both subtle and not-so-subtle effects. Reverb adjusts the size of the reverb tank, Space controls the “dwell” or input signal level, and Tweak controls the tone of the reverb signal.
ANALOG: Electronic reverb based on an obscure bucket-brigade echo circuit. This mode lacks all of the smoothing and diffusion of more modern reverb types, so you can hear each individual echo in the reverb tail. Reverb controls the delay time, Space controls the repeats of the echo, and Tweak adds an adjustable modulation effect.
