I'm going through a similar situation at the moment trying to get a 12 string sound, using a 4 string bass (splitting the signal into 2 full range and sending one through octave and chorus then into guitar combo and the other signal dry into a bass rig). I'm intrigued by those who are doing as I am and simply splitting a full range signal and sending one signal to the bass rig and the other (possibly effected) going to a guitar rig, without any issues from the guitar rig getting such a saturation of low fundamentals. Maybe it is the guitar combo I am using but as soon as I start turning up volumes above quiet house volume the guitar combo starts to fart, I'd imagine due to the full range (ie really low notes) signal going into an open backed guitar cab... not good!

Turn the low EQ down on the guitar amp!
