I played around with this for a while... and there's obviously some part I'm missing.
Running combo/amp 2 in the fx loop works but disengages the speaker in combo/amp 1. Bypassing the fx loop (with the switch on amp 1) gets you both cabs but they sound thin and weak together. The older of these two heads doesn't have a fx bypass switch, and I suspect therein lies at least one problem.
I think the XLR - 1/4" plug to DI plan would work, but splitting the signal from one bass and sending to two amps eq'd differently would get me closer to what I going for. It was just a crazy idea... I can't imagine any gig I'd ever need to run two heads anyway.
The simple goal here was just to have a backup Walkabout while the older one goes back to MB for current upgrades. After that, maybe I'll look at trading gear. Maybe pairing a couple really nice same-same 8ohm cabs with one WA, and leave the other WA docked in the 4ohm Scout combo cab for the small-room bar gigs or recording sessions.
Think I'll plug up and play some more.![]()
I coulda sworn the Mesa FX loop cut the line to the power amp from the Return jack and not the Send jack, but it's been a while since I screwed around with it so I could be wrong. If you want different EQ settings on both amps an active/buffered splitter is definitely the best choice!
