Had my kemper for a few months now and love it to bits, but since adding new profiles I have been having nightmares with foh sound, too much bass not enough mids etc.
the main output EQ working hard to sort it. I have a friend who has had a Kemper for quite some time and he asked me what it sounds like through HP's, and I said it didn't sound very good at all, his sound through HP's is great he tells me. That made me think, and it turns out that the main EQ out affects the whole tone of the HP's, so I have been fighting the main EQ the whole time. Now before I edit or EQ any profiles I set the main EQ all to 0db and now the HP's sound great and have loads of headroom with the main FOH EQ. The profiles I have already just needed to be tweaked a bit to sound good in the headphones and they now sound good in monitor out (Speaker) as well.
if only I had known that a few months ago, it would have saved a lot of messing about and late nights in search of the tone, It's probably in the manual and something I missed. Because the Main out EQ gets changed almost every gig, the next new profile get EQ settings to sound good with that particular setting, but now setting it to 0db before I start I'm winning every time.
