Hi, there!
Today I had a chance to profile some amps and I got some unusual hum and extra hiss whenever I connect the "Send" from Kemper to the amp's input. If I plug my guitar straight it into the amp, it works fine but plugging my guitar into the Kemper and then going to the amp's input (from Kemper's SEND) I got this massive increase of hiss, kinda like if I turn a crancked booster in front of amp, I mean really massive hiss.
Then I tried messing around with Kemper's ground buttons and on the best setting I got that's what happened, and in the worst setting, I got ridiculous amount of hum.
Any thoughts? Thanks in advance!
