From the post
The mother of all TS808 derivatives/variants, the Palisades incorporates just about every mod to the classic Tube Screamer circuit. Two rotary switches control the bass response (Bandwidth) and clipping (Voice), one toggle bypasses the input buffer while the other is a bright switch, a footswitch selects between 2 separate gain pots, and with an added boost section to round it all off. All 5 pots are board mounted, but there will still be a good bit of off board wiring. Schematic can be found over on FSB. It's laid out for a 1790NS enclosure just like the original.
And because I'm sure the off board wiring isn't the clearest, here's a full wiring diagram:
Hopefully that clarifies any questions and doesn't raise more... haha!
