No, it works like most tone controls, more treble clockwise. The kit is set up that way, though you can always wire that pot backwards to mimic the Rat. I wasn't going for vintage -correctness on this puppy, though. With all those modifications--both by BYOC and the ones I added--it would seem pretty pointless!

BTW, I have the original version of the BYOC Mouse myself, and it is wired per the Rat "filter" control in that one.
