Dual PLine (2.1mm 2-pack); 2
male, 2 female. 15" each. Plug into any BaseSnake channel. Limit use to: 1) two
isolated DC power supplies (wall warts), and 2) pedals whose supplies are rated
less than 800mA. Both sides share one ground wire, so it is always safe (no hum)
to apply within a single chain of pedals.
