RE: patch-diving......the only time I've really done that is when I can't find something I like. Something inspiring. Which has always happened with modelers. Find a decent amp sound, EQ the snot out of it.....then root through a pack of IRs. Drives me absolutely insane.
I'd spend forever comparing, tweaking and generally pissing myself off until I got something I thought reasonable. Then I'd come back the next day and think "What is THAT crap? ......you *liked* that?!?! Ultimately I settled on an Atomic AmpliFire for the last 4 years. Literally using ONE amp and ONE cabinet augmented with pedals. I was done tweaking, comparing and pissing myself off. The first time I plugged into a KPA was when the church bought one. I thought they were nuts......but I dialed up a clean profile of a Fender, twiddled the EQ ever so slightly and was off. In under 5 minutes I'd obliterated what to that point was considered an excellent sound by many who'd heard it.
That was December '18. My personal KPA arrived a little over a month ago and I have zero regrets. Been copping a lot of Freddie King of late with it. I kept my beloved dirt pedals, though. Even then, all but one sit on a shelf right now and that one is off most of the time.
I was concerned with a new model coming out "any time now". But, unlike modelers, profiles are not processor-intensive. New hardware isn't going to open some gateway to improved sounds. The KPA as-is isn't really being taxed.
Another way to think about it is Strymon. The Timeline has been out since 2011. It's certainly a matter of taste, but is anyone looking at Strymon going "When's the Timeline 2 coming?" and waiting as a result?
With the level of development going on right now (OS7, editor, Kone speaker, powered/unpowered Kab) I see zero indication that a new model is on the way any time soon. The amount of development bandwidth needed to do all of that AND create an entirely new box with 'new' features? Nah. Generally speaking, that's not how Germans go about their business.
