Gibson RD-79 Artist Active Preamp with Moog Expansion/Compression

[Axldeziak]

Here is a layout for the active preamp installed in the '79-'81 Gibson RD-79 Artist guitars. The circuit was designed by Bob Moog and includes a Expansion/Compressor.
I split the circuit into two layouts because of the size was getting rather large. Also, by having the EQ on a second board, it would give the builder a chance to experiment with different tonestacks.

Is the input of the bord comes from pickup selector switch?

Yes, the input comes from the pickup selector switch on the original schematic.
