I own the RB115 first then move to RB112 because I found RB112 sound better to my ear.
But I have no bar gigs experience with both combo.
If money no problems, Venture V3 + VB112 has nicer tone and more headroom even just 150watts on single cab. You can check my post on few day ago.
Thanks a lot Yahboy, yeah I just bought the V3, which I'm happy with and will work well for most all the gigs that my band does. But I was thinking of also getting a RB-112 or RB-115 for home practice/rehearsals . I don't really need to gig with it, but just wondered if the RB-112/115 might have enough power to work as a backup for smaller gigs.
