software

ok, i bought a dimarzio Air Norton for my neck strat, it already has a dimarzio evolution at the bridge, i really dont know abuot installing pickups, so a tech is gonna do it, i read that 500 k pots, are for maximum puch, but i dont even know what 500 k pots mean???? so, any other things i must know, like at what height should the pickup being installed, closer to the strings , etc, and how will it affect the sound. Im into, hard rock, 70s, jazz, fusion, funk, pop, all music really, so any advice, it would be great!!!
Thanks!

the evo is a great pup i just put it in my lp. i always adjust height until i think it sounds good, if the tech is doin it all then u dont have nething to worry about.
