Nothing Eric, i dropped them in my les paul custom and it happened to be my best guitar/bkp match. The sweat is not bright or dark, just balanced and as you say it has that midrange heaven crunch voicing thats so sweeeet. Diver and nailbomb bridge did not do a top job on the les paul, lacked a bit cut due to the heaviness I think. Its about 4.7kg heavy too. For a ceramic the bridge is surprisingly soft and nice sounding, vintage vibes are really there.
Also I went for a painkiller to try them as now except the pigs I tryed every comtemporary bkp. I must say its true, it does tchank tchank more than krown krown (recognize this eric ? :P) but it cuts nicely and pulls out decent cleans and stunning distorted tones. With my diezel its really punchy with a good amount of low mids packed with an amazing clarity and djent on fast riffs. Its surely not so huge sounding in the bass as a miracle man but I think its one of those pickup you gotta like in a band situation where its precision and mids can make the difference.
The gothic explorer is now a true metal machine, the bridge does not take prisonners but oh well I did not intend to play blues on this one :P. Kinda lost the rock feeling with the stock pickups but I guess its due to the mud they pull out. I tried it quickly in E to compare to the old gibson ceramics and nothing to say. The painkiller are the thrash gods.
