Just acquired my Kemper last week. I figured I'd give the profiling a whirl with an obscure old amp that I've had for a while. It's a Gretsch Electromatic from 1951. I profiled it with an SM57, but like the Sennheiser e609 profiles a lot better. I profiled with the volume low and high for different gains and also with the "regular" and "treble" input options. Would love for those more experienced here to let me know how I did and what I can do better! Thanks in advance...
