Since Ric-o-sound is two channels you use a stereo cable that feeds two amps (or in your case two channels). Thus tip is one channel and ring is the second channel. Of course at the AMP you need some kind of Y cable or adapter to split the two signals from the stereo cable to each amp.
I have a Resoguitar I set up this way. Really sounds GREAT by the way.
But what about a mono bass? Well things aren't so simple! The easiest way to deal with say a passive P-bass is to change the jack on the bass. If you put in a stereo jack and wire tip and ring together, when you plug in your stereo cable it will feed the mono P-bass signal to both channels. Cool! Simple.
However, that was a passive bass. With an active bass the ring teminal is usually the battery switch so no mod like that can be made. In this case you need to build a Y adapter box at the amp where in stereo position it feeds tip and ring to each channel, while in mono position it feeds tip to BOTH channels and ring is grounded to turn the battery on. This kind of adapter box will ALSO work with passive basses without modifying their jack.
That's the story. And by the way, I've found that if you use effects, especially the kind that have stereo outputs (as some do) a bass with effects with stereo outputs into TWO amps sounds MUCH better than the same bass and effects into a mono rig. However if you want to have all this going: Ric-o-sound, mono bass, and stereo bass effects, the switching box becomes a true nightmare. In that case I'd urge using one of the small mixers you can pick up cheap instead.
