After playing through the factory Rigs, I wish I'd limited myself to the free Rig Packs and Rig Exchange.
Would've saved a whole lotta money and probably found many Rigs good enough to see me through. Once you take a bite out of the commercial-Profile cherry, it's hard to stop there...
I am the exact polar opposite. Had I been limited to only the factory rigs and the Rig Exchange my Kemper would have been on Craigslist within a month (I traded for a used powered toaster, foot controller and bag). I'd had my eye on the Kemper for a while and after browsing some of the commercial profile sellers I made a mental note that the first pack I would buy would be Michael Britt's Jim Kelley pack. Indeed, the evening I got my Kemper I purchased and installed the Kelley pack. I thought I'd died and went to heaven. I knew that evening the Kemper was here to stay.
I get what you are saying about the commercial profile rabbit hole. it happens. I've bought a bunch of them and many (most) were loaded, demoed and deleted never having sounded nearly as good as the demo videos on their website(s). In the end, the only profiles I play are packs I purchased from Michael Britt. There is just something about the way he profiles an amp that is pleasing to my ear. I finally convinced myself I'll never find profiles I like as well as the MB packs and I was able to get that commercial profile monkey off my back.
I wouldn't have done anything differently except maybe pulling the trigger sooner. I regret that didn't take the leap of faith earlier.
