There is almost no discernible difference to me in those last two Dual/Quad tracks... but you can definitely "feel" it more in the "quad" file... I'd say quad track, but don't use that tone as your final... theres something weird/squishy about it...
Yeah man I've been quite concerned with the tone lately and I can't put my finger on why. I like it, it's aggressive and has the right "size" but there's something about the body of it that bugs me. Like there's no weight to it, no substance so to speak. Too much gain perhaps? I don't think so though... What would you guys suggest?
