Well, as a sound engineer and producer, I indeed spend way more time auditioning sound and sculpting them than playing... I'm not seeking for "MY" tones and sounds... I'm seeking for everyone else tones and sounds. That's why, the more the better. I already spend a week with the Kemper at the previous studio, and it went from 50 to 500 profiles in a week... and it was just some test.
So yeah, a dozen of profiles wouldn't work at all and wouldn't be more than enough for me. We already have more real amps at the current studios. But it's a real PITA to carry them now that I have back injury. That's where the Kemper could become handy and I could still get the same sound at home by only carrying the Kemper around.
Anyway, no need to argue about that. As said, to each his own. I got the info I was looking for.
Thanks guys!

Just a suggestion, but you can get a Microsoft Surface and just leave it in your rack (I know, you said you have an iPhone - I'm an Apple guy myself, but these are seriously nice tablets), connected via USB to the Kemper, and store all you want on there. You can find a used one for pretty cheap, though I'd opt for at least the Surface 3, which you can get new for $500, used for probably $300. You don't need anything more than the base model. Each profile only takes up approximately 4k of storage space, so you could easily store 3k rigs on a device like this, and connect to WiFi to get more if you need to. Plus, it's lightweight, and would fit in a rack, possibly even between the top or bottom mounted unit and the case itself, or in one of the lids.
Additionally, it's a much better interface for searching, as you can type in what you need and find what you want quickly. The "filtering" functionality on the Kemper works well for a few dozen rigs, but it loses its usefulness when you get in the hundreds. And, if you're recording someone, you want to work as quickly and efficiently as possible to nail down the sound they should use; putzing around on the front panel of the Kemper for 10 minutes trying to find that one rig that's awkwardly named is going to make the client mad at you and less likely to return to your studio. Being able to search, filter, make folders, and instantly preview and load a profile onto the device with a few taps and keystrokes will make your clients much happier.
As an added benefit, you can then make performances of the band's setups, save them on the tablet, and remove them from the device. If they need to come in at a later time to, say, retrack a solo or redo a rhythm part, you have their sounds available to you on your tablet - load up the performance for the song, and you're right back to where you were before, edits to the profile completely intact.
The Kemper not being able to store 3k rigs is understandable, because it's not feasible to use it in that manner, nor was it designed to be used this way. Each rig is pulled from the database and loaded into memory (RAM) from flash storage on boot, which is part of the reason it takes time to boot up the Kemper, and why, when something gets messed up, it often takes a long, long time to load the database into memory. Even though each profile's file may only be 4k each, at 1000 rigs, that's only 4MB. But then they need to be processed each individually, which expands the memory footprint. That said, my best guess is the Kemper probably only has about 32MB of memory (RAM) on board. There's no need for more for a device of its nature - it does what it needs to do, keeps costs down, developers paid, and updates coming. It's the same reason your internet router in your home doesn't have a Core i7 processor in it - it doesn't need it to handle what it does.
You won't find other devices that can handle that much either. An AxeFX has 768 presets you can choose from, but it's with a specific set of predefined amplifiers. Line 6's typically have 32 banks of 4 presets, totaling 128 presets you can use, but, again, with predefined amplifiers. Out of the box, the Kemper is still more capable than all of these other devices in terms of storage. The only thing more capable would be something like Logic + a ton of plugins.
Not trying to argue or persuade, just trying to bring up some concepts, as a fellow researcher that wants to know everything about everything before a purchase, that you may not have thought of. Good luck!
