Thanks for the responses guys.
After browsing some other similar threads (should have done that before creating this one!) I am leaning toward the powered version. I believe this will give me access to the most options - guitar cab, active FRFR, Passive FRFR. This is all new to me so please tell me if I'm missing something.
Questions:
-Assuming I eventually decide to use my KPA live, if I went straight to FOH can I still make use of the options I listed above? I'm assuming it's possible (but maybe not?), but is it desirable?
-How can I be sure that the signal going to FOH matches what I'm hearing on stage?
-Slightly off topic...I have watched a lot of videos and listened to many samples online, but most of them are very pristine quality using much more distortion than I would use (I don't play metal). I am curious how well I'd be able to get very classic, psychedelic late 60's early 70's guitar sounds...without the modern pristine "sheen". I like those sounds as well, but the project I'm most interested in using the KPA with is really trying to dial in vintage sounds - warts and all. I want it to be dark and much less "shiny" than modern guitar sounds. Less hi-fi. Hendrix, early Gilmour, Cream etc. I know the KPA is capable of doing very high quality stuff, but can it go really vintage?
Really starting to get excited about this...I've been wanting a KPA for years and it's finally coming within reach.
Thanks again!
