After a lot of deliberation I went ahead and ordered a KPA. I'm pretty excited. I had been contemplating going with a POD HD500/DT25/ISO cab set up (it needs to be silent to quiet for my living situation) but I came to the conclusion that the isolation cabs under $1000 weren't worth considering and that would push me over my budget.
I've been using alternative guitar amp tech for a long time. I think my first set up of this nature was an ART SGX2000 with a couple of Peavey KB60 keyboard amps. Somehow I got some crazy sound out of that rig... some even good! I think from there I went to a crazy system that used an Ampeg SC140 amp with a Digitech 2120 in it's effect loop but I took one of the stereo outs and ran it into a keyboard amp for extra "stereo" fun. Next rig was a Vox Tonelab SE into a Lexicon MPX-1 into Mackie powered PA speakers. Actual tube amp? It's been a really long time... (and I guess that's going to continue getting longer) I also did the Roland GR based synth thing for years, but I finally gave up on that as failed tech and taught myself basic keyboard skills. I love synths and I have a few analogs at home as well as a VST folder full of goodies. These days I mostly jam around my home studio using Ableton Live and some software loopers like Mobius and Augustus loop.
