NLC1142 Isolate

Based on the Isolators on the SP-808. They are simple EQ filters, all manually controlled.

The core circuit is based on a section of the PGM Isolator, don’t know where that came from, probably a 70s electronic hobby magazine.

The input stage boosts the signal by approx. 1.5x, feel free to adjust this (15k on the input op amp).

Feed them some drums and tweak.
