Mulitples
Multipoles is a funky little mult with visual indication of +ve and -ve going signals via it’s red and green LEDs. There is a very small draw on incoming signals used to power the LEDs, so Multipoles should not be used where 1V/oct is important – but you’d use a buffered mult for that anyway wouldn’t you?

These merchants probably sell this module. Huh?
