I've watched a few of the side-by-side demos and is it me or it just sounds great?
I think I had a '59 at one point in the bridge of my Strat (picture a loud, ballsy, bassy Strat tone) but it was too low output. Sounded very good though.
I have two SSL-1s in the other positions and it seems the SH-16 would be perfect there: use the higher output Custom coil for splits, and have a medium output bridge pickup that won't overpower the single coils as the Custom would.
This Strat has eaten the following pickups:
Alnico II Pro
And I still have a C5 I've not yet put in...
The AII was probably the better sounding, followed by the AT-1 which has a richer sound. Brobucker, PATB were too middy, Crawler was too high output, Jazz and '59 were too low output.
