I hope you have found a way to organize and browse that mess.
The new 1.1.1 has some nice functions for that. You can sort by amp and gain and you can filter by some criteria. For me the "sorting by amp" is the most important function. Unfortunately many profiles either don't have that tag filled at all or the naming schemes are so different, you can't really sort that out.
But there is a solution:
Our fellow forumnite Laurent has just released a Rig Extractor that doesn't only export tags to a csv-file but can also batch process all profiles after editing the csv file with something like Excel. So I did a backup of my 1.700 profiles, extract the rigs from the resulting backup file (which is a tar file after all). I created a csv-file with Laurents software, edited the tags to my liking and processed all 1.700 files in one go. I then put them back in the kpabackup-file and did a restore on the Kemper.
Voila, all 1700 profiles have the "amp"-tag in a naming scheme I could handle. With that the "sort by amp" gives me all I want. I have all Marshall, Fender, Vox, etc. profiles lined up.
It's really no problem handly those amounts of profiles now.
