My third time around with the AF. I now have an AF6. The issue is, I can't seem to dial out obnoxious spikes. When I try to dial them out using low pass and a parametric with a narrow Q, it kills the high end excessively and the presets all sound thin and very POD like. F.Y.I...I use the AF6 in a rack with a Lexicon PCM 81 a few SE-70's and line mixer. All this goes to a VHT 2/50/2 power amp and two 4x12's with celestion v30's. My analog pre-amps sound amazing through this setup, but I wanted to dial in the AF6 for other tones. It's SO bad that after an hour or less of tweaking, my ears are SHOT. My ears are completely fried, my tinnitus kicks in, then it's 48 hours or so of no guitar. I switch off the IR's, I tried the power amp emulations and they sound awful. About the only way I can get a realistic sound/tone is by either using the Filter setting instead of a cab setting. I've owned many digital pre-amp and never had so much issue with setting up eq. Don't even get me started on clipping and levels...thoughts? experiences? help?
