tell us what you wish to do, ie in the same way you done with a “traditional” rig ( all the way from unloading the van, carry gear to stage, plug in, how you wish soundcheck, want to hear, how you monitor, how/if you tweak during a performance, what you wish to avoid, etc, etc)
The infinite options and flexibility of the kpa are its strength but it can be overwhelming. It is still nice (and possible) to drop your rig on stage and plug’n’play worrying about nothing else apart from your playing (and what freebies are on the rider) i recall when i first had mine, I was more worried about how to work it and the “what ifs” but compared to many other “amp modellers” i spend more time enjoying playing than knob-twiddling.
Like any new bit of-tech gear, compared to its old analogue counterpart, (your new phone/car/online-banking) the technicality of it and fear of the unseen/unknown can detract from the original intention.
maybe you cant see the wood for the trees but it won't take long to build your confidence in the choice you have made.
ps, Why did you choose a kpa?
Pps do have the opportunity to shadow someone who uses a kpa live in the way you wish to do so?
