I might have to take some words back.. Ok, 3 opamps (1 quad with the
infamous "Ground Follower"), 2 caps, 2 resistors, about 1 square inch
of PCB and this pot - You'll have an universal bipolar attenuator,
that follows modular I/O impedance requirements and can be fitted
nearly everywhere.. would that be next Bridechamber "module"? ;)

If someone just forgets to use this wonderful toy in the design.. just
add it. Maybe some panel designs might also come with +/-5 scales and
this Wonderful Gadget :D As seen on TvShop: "Finally I can leave My
VCOs bipolar modulation input connected, without having to hunt down
why Pitch wanderers, Thanks to this perfect solution! Order Now.."
