Alesis Microverb 3

OVERVIEW Budget rackmount digital effect with no display, no midi and missing saving option.
The Microverber 3 offers 16 bit linear PCM and 256 programs: 144 reverb programs +  96 delay programs + 16 special effects programs as well as High and Low Frequency Equalization.  Pretty intuitive with three potentiometers on the left set the input level  the processed / unprocessed signal balance (mix), and the output level. On the right, two rotary switches with sixteen positions allow you to select the algorithm and its variation. In the center, a two-band equalizer corrects the processed signal.

ALGORITHMS There are nine reverberation algorithms: rooms (small, medium, large), halls (medium, large), plates, chambers, gates, and reverse. The other seven include five delays (short, medium, long, medium with feedback, long with feedback), a multitap, plus a special effects category (FX). Sixteen variations are available for each of these sixteen algorithms. In terms of reverbs, they act over time, the acoustics of the simulated space and attack.
