The Music Thing Modular Spring Reverb Mkii is a flexible, voltage
controlled mono spring reverb module. Traditional guitar reverbs are
tuned to the sound of the guitar and the amplifier it is played
through. This circuit is different, it is designed to be relatively clean and
high-fi, with a lot of bass response.
The module works with either external
electromechanical reverb tanks or a solid-state reverb 'brick' from
Accutronics that fits on the back of the module. This module has the solid state Accutronics reverb module BTDR-2H installed. More information can be found here. musicthing.co.uk/pages/spring.html modulargrid.net/e/music-thing-modular-spring-reverb-mkii
