so i went to sam ash today, and i was gonna get a set of pearly gates. i wasnt really sure what sound i was after, but i thought a billy gibbons sound would be nice. i talked to the salesman at sam ash and he was a good guy and he was explaining to me how the evolution sounded and i thought it might be something id want. so he tried out an ibanez for me which had the ibz pickups in it, just to give me some sort of idea what to expect. i loved the sound he was getting through the jsx head. so i decided to buy the evolution bridge and the tone zone bridge, that going in the neck posiition for my lp. i really like the sound im getting from them. im thinking ill raise the evo's height a bit because the tone zone is louder right now, but other than that minor problem it is awesome. the evo has great definition and clarity under high gain. when playing more than 1 string at time, you can hear each note individually. it was a world of difference compared to the 500t. the tone zone is decent. its not an awesome pickup, but i like it. it gives nice sustain and a nice sound that i can use. my lp can sound very similar to the steve vai song "jibboom" now. this is prolly a bad example, but im not familiar with any other pieces by him.
