It's a fair question Ochaye.There's a great vid on you tube comparing Gibson 57's (i think) with mules, the one where theguy uses a park amp.There's not much in it if you listen, although youtube may corrupt the sound, but this would penalise both pups wouldn't it ?
The most crucial problem in recording guitars is mic placement, and 99% of gear test videos on youtube are very poorly recorded.
Place the mic half an inch to the left and a 59' Les Paul plugged into an old Vox AC30 sounds like one of those Ibanez' with the friggin monkey grip played through a Line 6. I'm currently recording some new tracks with my band, and we've been struggling with mic placement in the new recording room for a week. It can just drive you crazy.
My Engl E650 sounds like utter shitee in every single youtube video I found, and it sounds like an absolute killer in reality.
Everytime I'm interested in a new piece of gear, I go on youtube and watch every video with it, only to realize I need to go to the store and just try for myself :)
