I'm working with a group that requires a multi-amp set up using a
Motion 200S keyboard amp, an SWR bass rig and Rivera Knucklehead with
a 2x12 bottom. I've been splitting the A Guitar and B Guitar output
hard L & R to the VG's Mix output, sending the mono bass and mono
guitar to their prospective rigs,

Now for my "typical" VG-99 A/B guitar set-up, I want to output the A
guitar in stereo to the keyboard amp and the "B" guitar (VG bass)
mono to the SWR rig. What is the most effective way of doing this?

I can send the stereo A guitar out via the VG's Mix Output but can't
get a good Mono out to the SWR rig. I tried the Sub Out, but the LR
to bass amp input didn't cut it. Do I need a direct box to
compensate for the Subs XLR output?

Is it possible to send the bass out through the VG-99's Guitar
Direct Out?
