Finally have my rig in order - will be using it at practice on Wednesday.
Kemper Power Rack is in a SKB 4U Roto Shallow rack case. In the 1U space above the Kemper is my Shure GLX-D Wireless and the Lehle P-Split II. The splitter receives the guitar signal from the wireless unit and then sends the guitar signal to the Kemper and the VoiceLive 3 Extreme (VL3x). The wireless and splitter have not been mounted properly yet. I don't want to mount them directly on the Kemper because it gets hot, so will likely get a 1U shelf to put them on.
On top of the rack case is an Alto TS210. I use this as my cabinet for my amp at practice. For live performances the Kemper will go to the Mixer and then be monitored along with everything else with a tailored mix through my floor monitor, an Alto TS212.
The TS210 and Rack Case sit on an OnStage RS7000B amp stand, behind me.
In front of me is the VL3x and the Kemper Remote with a DVP4 X Mini pedal I use as an expression pedal. I only have to run two cables from the Kemper to me (CAT5 to remote, Guitar Cable to VL3x). The VL3x is strictly used for vocals. The guitar input is so that the VL3x can determine the song key to create proper harmonies. I could have gotten away with using just the VL3x without the Kemper, but the electric guitar sounds are horrible and the amount of noise that comes from the guitar outs on it is unacceptable. I do use it with my acoustic guitar and it makes for a really compact solution for those solo gigs.
Both the remote and the DVP4 fit in the back rack case lid, barely. I put the remote's CAT5 cable inside the rack case as well. The VL3x has it's own hardshell with foam case.
I had a VoiceLive 3 too. Couldn't believe how bad the amp models were. Worse than a cheap, Zoom fx pedal. Such a shame, as the vocal processing was superb. I was hoping it would have been a nice, simple, all-in-one solution. I was gutted when I realised it wasn't even close.
