I've bought an Audio Interface (Line 6 Studio UX2) some years ago and I've always connected from my guitar to my iMac. I usually recorded metal/metalcore riff, tried different VST plugins (Guitar Rig, Amplitube, Pod Farm, TSE505 ) but I've never heard a CLEAR sound from my mac cables. The maximum acceptable result is during "breakdown" steps but if I need to clear the sound for riffs it become crappy. I hear like if middle frequency are very ugly and never warm, similar to phone call sensation, far sound. I've updated the audio interface drivers.
My Mac RAM : 4 GB My Mac OS: Mavericks Sometimes it's hard for it to manage the project but it works anyway. Sometimes I have a few latency but if I switch the Audio interface from the settings it keep working well (it seems)
My Guitar: Jackson Dinky (Jackson pickups) Made in India Floyd Rose, Ernie Ball Strings
Audio Interface: Line 6 Studio UX 2
Jackson Dinky -> Line 6 Studio UX 2 (Instrument) -> iMac USB (Reaper)
An example (maybe not the ugliest one I recorded): http://justtest.altervista.org/pr/metal.mp3
Thanks for help!
P.S. Maybe it's me that overestimate audio interface. All the stuff I hear on youtube are much more better to listen than my stuff. My sounds are boring
