Been using my JTV59 / Helix / PC112+ for the last several gigs. Tried using PC112+ in FRFR mode and IRs in Helix. Didn't dig that much, but didn't spend a lot of time on it either. Thought about moving the IRs to the PC112+. Didn't get that far. Tried the PC112+ speaker emulations first. Fantastic! Finally feels like I am playing an actual amp, very happy with my sound on stage. Tried using XLR out of PC112+ to FOH, rather than XLR out of the Helix to FOH as I was doing prior. Was not as pleased with the XLR out of the PC112+ to FOH. I use a lot of 4x12 IRs in the Helix and the PC112+ is only emulating a 1x12 setup so I really wasn't too surprised there. Back to tapping the Helix directly to FOH. I also use the PC112+ in FRFR mode when using the JTV59 for any acoustic stuff. Sounds great on stage as well. So I am using the PC112+ for stage monitoring only, but I really dig it - and it can get plenty loud to keep up with the rest of the guys! My only issue is the loud volume spike that you can get if you are in the middle of hitting anything on the guitar and switch from FRFR mode to speaker. I have to make sure I am not sending any signal from my guitar to the PC112+ when switching. More than a bit of a problem, but I can work with it for now. Hopefully they address the issue soon, can't imagine I am the only one to run across this when playing live. Sold some more gear I wasn't using and scored a second PC112+. Haven't used the two together yet. One's at the practice pad, one's at home. Soon. Looking forward to checking out dual amp / dual speaker type setups. Oh yeah, and I only need to run one AES cable to the PC112+ from the Helix. Fabulous. Overall, very pleased!
