"Amazing, Amazing, Amazing!!!!!!! I bought the original Paul Stanley back in 1978 I believe and I'll never forget the sound those DiMarzio Super 2's cranked out through my Marshall. Well I came across this one, the cracked mirrored one yet, was skeptical but figured at the least it'll go on my wall with other collectibles. I plugged in and it was 1978 all over again, it screams, has the weight and it's beautiful, matter of fact I have a gig Saturday and it's coming with me!!!!"
