This is my opinion - and that's all it is. It's your money.
If one rig/performance and their associated effects are all you're going to use, why bother with a Profiler?
It's like buying a Ferrari and only driving it in 25mph zones, once on the third Sunday....in June. You can do it....but what an incredible waste of capability.
I own a bunch of vintage and boutique amps, a bunch of pedals, rack fx, various cabs and so on, but the KPA is:
Smaller by far than any pedalboard amp combination I have.
Easier to set up.
Faster getting sounds in a session.
So far, it’s more reliable. Far fewer patch cables to fail, no tubes.
More sonically consistent.
Generally more versatile although I still occasionally use some pedal fx that seem better than the digital KPA versions.
The only things I’m not switching around are my current fave amp/cab profile, and if/when I change my mind I can find a new profile. The big thing is, I want to *play* the KPA, not simply switch to a new patch for each song.
As far as a Ferrari, that would be my Sampson era Matchless HC-30 and 2x12 cab. High performance, high purchase price, high cost of maintenance, but nearly pointless as a daily driver, especially if volume and hearing loss are issues.
