Hi Kemper board!
Edit: I fixed the problem by reducing the cab volume from 5 to 0. I had the rig and stack volumes pretty unbalanced, now both are back at 0 and the popping is gone.
I just noticed some strange pops, but only with the studio EQ engaged. I had to do some heavily muted C5 powerchords (I'm in drop C), mute the chord instantly and really dig into the string, but then they really popped out.
Rig is here: http://kemper-amps.com/api/dow…e9M28mtfl1zqDkjbjT7?.kipr (Name: ara_TillS 860 2 MICS, customized Engl profile by Till, awesome stuff btw)
My Studio EQ settings, for convenience.
Low: 125.5 Hz, -7.5db (I also got pops at 60Hz, but 125.5 is the current value, so, yeah)
High: 9576.2Hz, -6.3db
Both Mids at 0db and 0.707Q
My Guitar: Ibanez RG1XXV (Basswood, bolt-on maple neck with walnut stripes, blocked Ibanez Trem) with Bareknuckle Painkiller pickups, bridge selected, obviously.
I got the pops with FRFR speaker on right main out, headphones on headphone out, and left main out into Line 6 UX1 interface into Reaper.
I hope I've been thorough enough and this helps improve an awesome product!
PS: Take a look at the profile if you're into Higain and haven't tried Tills profiles yet, it's awesome and my main tone.
