Fostex 3180 Reverb

[Mark Hammer]

Someone had one for sale locally for a decent price so I dug around for technical info about it and found this pdf'd schematic for this reverb unit the other day: http://www.silentarts.de/lab/forum/3180_Shematic.pdf

Interesting circuit.  Though the external controls do not seem to show it, you can adjust for predelay via an MN3007.  You will note that it also includes a single NE570/571 compander chip used as two compressor sections (i.e., no re-expansion) as "boing-protection".

can I use an expression-pedal to modulate the pre-delay
and the reverb density?
anybody got a layout for this?
how to fit it onto a BB case?

sorry, Mark - had to do it...
(a joke a year keeps the head clear  )





thank you for this interesting tour de scheme!
