I need advise on guitar selections. I'm looking right now at epiphone les pauls and esp guitars but i havent played esp yet. I'm looking In the price range between $600-$700. Features i like on guitars are: tremolo, fast neck, and a really good CLEAN SOUND. A guitar im really interested in is the epiphone black beauty but ive also heard it's specialty is the 3rd pickup so what difference does that make? overall = good quality
