Re: Kemper Profiling Amp
I had one for a bit. Two things killed it for me -
1 - No editing software. All edits are done from the front panel. It's intuitive enough, but still a little klunky.
2 - You can only edit profiles so much before they start sounding too digital. When you're dealing with modeling, they do their best to model the actual knobs on the amp, so each amp reacts differently, and hopefully, more true to the original amp. When editing on the Kemper, it's all linear, and you can only adjust so much before it sounds really odd. When I had mine, they had *just* updated the software to let you swap cabs, but it was still sounding a little off to me. When you're swapping cabs/IRs on a modeler, you can really tell the difference between an Orange 4x12 mic'd with a 57 and a Mesa 2x12 mic'd with a 121.
Couple that with the fact that I didn't have my own rig to profile, I was dealing with whatever profiles were available on the Kemper site. There's plenty of good "payware" profiles out there, but after dropping nearly $2k on a unit, you just don't want to drop any more money on it find your sound. I found my sound through a combination of modelers, solid state amps, IRs, pedals, preamps, etc, so I sold the Kemper off.
If they can fix these two things with the next generation Kemper, I may pick one up again. I think they'd be able to profile the knobs easily enough. Tell it how many knobs it has, and then take snapshots of the knobs at various points. Then it would react more like the original amp.
