Fatman Mods

Fatman mods

I was reading the manual during class a while ago, kinda bored with the teacher lecture I guess, and the manual says that the Fatman's VCF is a multimode. So I went through my notes and used this info for a mod. The Fatman's VCF is not only a LPF but a BPF as well! not only that but the mod was done in only 5 min.

First remove the positive side of C23 and attach that to the center pole of a SPDT switch. Then run a wire from the the board where you just removed C23 to one of the other poles on the switch. Connect a lead from pin 8 of Ic17 to the last remaning pole on the switch, and now you have a choice of either LPF or BPF mode!

Why didn't any body do this mod before? or if you did why was it not on any of the mod's pages? anyway.... good luck
