Spring Reverb

Digital reverb (6HP)

Based on:

My version of Music Thing Modular's Spring Reverb (Mk2). There are no RCA connectors for an actual spring reverb tank on this board, though there are jumper pads available to add one (similar to the official expander). I exclusively use this module with the digital Belton BTDR-2 reverb.

Build notes

The crossfade uses a vactrol, so some resistors may need tweaking to get a good dry/wet separation. I put in an extra trimmer to facilitate this but some additional experimentation could be required.
