Having had my KPA only a couple weeks I'm still very much a newb. That said, I was able to find (purchase) some really great profiles that are in the ballpark of what I need tonally to get through my gigs. The first gigs were last weekend - night one was rough as, besides the new rig (totally new paradigm in fact) it was also my first time ever using in ear monitors. I bought both at the same time to move into this new way of doing things - no more volume wars, pissed off club owners or others saying I'm too loud.
So, the first night was rough but not terrible. I did some tweaking at soundcheck the next night, after that it all sounded really good.
So then I brought the Kemper back home for more tweaking - decided to profile some of my amps. I did my Fender '68 Custom Deluxe first with varying settings. Using the profile from the setting I use most often for gigging, it's damn near indistinguishable from the Fender.
I did a couple other amps using a Suhr Reactive loadbox and impulse responses, the results were mixed. Some turned out great, others not so much. My Bugera 1960 Infinium (cheap Plexi clone), both alone and combined with my Laney AOR100 turned out really good. My Marshall DSL100 with custom mod turned out pretty bad.
Then I profiled the DSL using an old Marshall 4x12 with WGS speakers using a 421 and 57. Holy cow! The profiles sound really, REALLY similar to the amp (and the amp has been custom modified by Voodoo Amps with my signature mod) - like if someone had gone into the amp and fixed up the infinitesimal things that weren't already perfect with the sound.
The one thing, thus far, that I haven't been able to grasp is getting the onboard compressor stomp effect to mimic the effect that my MXR Dynacomp has on my Deluxe. I've plugged that pedal in and setting it the way I normally do into the profile of the Fender, it reacts EXACTLY like the actual Fender does. Incredible!!!!! But I can't seem to get the Kemper's comp to be the same. Hopefully with some more tweaking I'll get it cause it's pretty essential for the sounds I use & I'd hate to run cables out to the front of the stage for one stinking pedal LOL.
We had band rehearsal last night, I used the KPA into a Marshall 4x12 (using the Kemper's onboard power amp). It didn't sound as good as I'd have liked, well, the clean sounds anyhow, mostly because of the compressor thing. The Marshall profile sounded immense!!!!! I did some tweaking throughout the evening but after thinking about it, I'm gonna restore the originally programmed settings from a backup I made before rehearsal because what I'd programmed sounded amazing through my studio monitors - I think that's a more accurate representation of what I will hear through the PA than what I hear from a 4x12 cab. I'm gigging in a few hours, so I'll be able to hear what the new sounds sound like - if they're not working I still have the performance setup from last weekend to fall back on for this weekend.
Anyhow, the moral of all of this is that, at least amp-wise, I'm astonished at the realism - especially now after profiling amps that I've owned for years (well over a decade in the case of my modded DSL).
Now - if I can just figure out a way to get all of my neighbors in the surrounding 3 or 4 blocks to take a day trip somewhere for 6 or 7 hours I'd love to get profiles of this Bugera Plexi clone, my Dual Rectifier, 1965 Fender Bassman and the Laney all using speaker cabs and mics LOL!!!! What heaven I'd be in then!
I love this rig!
