Delay No More

Two PT2399 chips roped together in series, one with vactrol control, and four feedback paths: 'it's just a disaster', and one of the most popular NLC modules, from sweet to slow motion train wreck. fbA and fbB feed each delay back on itself, ffA>B and fbB>A across; coarse and fine set the first delay's time, delayB the second's; wet/dry blends dry and delayed (mix on the photographed panel). CV drives the vactrol, its LED on the panel.

Key features
