I have Texas Specials in there now. Maybe something stacked that matches well for more versitility. Not a metal pickup but one for classic rock/heavy rock.
Ive got a Hot Rails in the bridge of one of my Strats and I like it quite a bit. It is a very dynamic pickup, I like the midrange it has. Also, don't know if your interested in a full size HB, but I have a Pearly Gates in the bridge of another Strat and I absolutely love it, I think it works really well.
And whatd'ya know? They have a custom shop Pearly Gates in a Single Coil size stack like the Lil '59! They even have an option for "no logo" and "aged cream!".
I just found out about this - and I think I am going to try it! Maybe they'll do the EVH in this footprint too eventually.
