Hi folks,

First time poster here with a quick Q about ye venerable proco rat layout.
I'm interested in building a sort of vero test board up with the rat's power/clipping/output section, but that replaces the filter/eq section with input and output jumper points. The idea being that I'd like to try a couple of different active EQ circuits and it would be simpler to just build secondary boards for FMV/baxandall/HM2/etc and keep patching them into something that already exists.

All that said, I'm still at the bottom of the mountain when it comes to this stuff, so while I can follow a layout pretty confidently, knowing how to succesfully move things around is a little beyond me.

My understanding is that the rat's filter stage is just a simple passive LPF made up of the pot, the 1.5K resistor and the 3.3nF cap, so leaving the filter knob fully ccw would be pretty much the same things as leaving it out altogether?

If so, would I replace the 1.5K resistor w/ a jumper, then use the leads to Filter 1 and Filter 2/3 as in and out points? Would I still need the 3.3nF going to ground or would I just omit that altogether?

Basically, I think I just need to stick two jumper points between D2 and C9 and then plug some junk into it... am I on the right track?

Thanks in advance!
