Please make a layout for the old MXR Sustain from the Commande Series!
Based on ca3080, but it's placed in the negative feedback loop of the opamp. Limited range of controls, compared to a Dynacomp, but a very natural sound and much lower noise.
The original pedals were quite low quality, plastic enclosure and cheap circuit boards.
There's a tracing thread at freestompboxes.org...
I think it's possible to squeeze this into a 1590b.
