Update.
Did a bunch of gigs with the Kemper and this thing is a dream!:
- Sound-engineers who know these strange blinking boxes smile when I take it out (the Kemper that is...), the other ones smile afterwards.
- Got rid of my two Camper 112's FRFR. They sound amazing but I decided to settle for a bit less in sound quality and save room in the trunk of my car and on stage with a single Yamaha DXR10.
- To make the very most of high-Z mic's you got to increase the input impedance of the Kemper. I use a 10 Meg buffer (Lone Wolf Terminator) but a Lehle Sunday driver or any (DIY) FET-buffer with a 5M+ impedance will work. The "standard" 1 Meg on the Kemper is ok but an increase will get you a lot more "Umph", especially with cristal/bullit mics.
- When profiling: Ribbon Mics! Dead Centre. My experience mic'ing for harp the centre of the speaker is where the interesting stuff happens harmonics-wise. A ribbon mic seems to captures them and smooth them out in a sexy way, where a dynamic mic (Sennheiser e906) captures them in a nasty way, EQ'ing doesn't make it better.
Almost forgot to mention:
- For all you tube-extremists out there (which I still consider myself to be): I own more tube-amps now, then I ever did before I owned a Kemper. Sold my big amps and got a bunch of small bargain-bin vintage tube screamers with money to spare. Pure tone over stage-volume compromise....
