I just got a bunch in the mail and after living with them a couple days, I am seriously impressed. they sound dramatically different than anything I've ever tried. it really hit home this evening when we were laying some scratch tracks for a new song - in playback my lead tone was sweeter (for want of a better word). My guitar seems to sustain and resonate more, and harmonics pop out easier, all while the overall tone seems mellower yet clearer. I like!!
