This is an Art Multiverb LT from 1990. It is a very a basic, budget digital reverb and multi effects unit with some really cool fake "plates" and gated reverb sounds. This overclocking (actually technically "re-clocking") mod makes the unit have extremely bizarre, bit-crushed effects for a wide variety of applications by replacing the fixed timing crystal found in the unit with a modern LTC1799 precision oscillator and variable controls.

This is a demo on a dry snare drum track. My signal chain was the snare drum track sent out of Pro Tools into the left mono input of the Multiverb, and then the stereo out of the Multiverb back into Pro Tools. I/O was through Burl Mothership converters.
I did these mods based on the guide available from Circuit Benders (link below). I made a small circuit board for the LTC1799 oscillator IC based on the data sheet and Circuit Benders adaptation of it. I have a link to order this PCB further down. The trimmer on the PCB is used to fine-tune the clock speed to ensure the control pots on the front panel are actually usable.
