If its one thing I hate its having to drill down through menus to make changes to my amp's settings. I had an ADA MB-1 for a while. Not my thing. There's plenty of great sounding simple amps out there.
Well that's where the promise of programmability comes in; the problem is playing bass is not like playing a synth patch. You might have to make changes on the fly to your "programs" to suit the venue and yes a programmable setup complicates that.
The Kemper stuff does seem to include a lot of knobs (like a virtual analog synthesizer) but I think the reality is most bass players don't need that level of programmability.
Hell as it is a lot of the keyboard players I know find their 10 favorite patches on a given keyboard and just use those over and over again.
Jordan Ruddess does not do this but he's also freaking Jordan Ruddess!
