I just had the PTC swap out my Archtop Treble and Bass pickups with 57/08s (and had them install mini-switches to split the coils individually,) and they are awesome. Granted, I have a Hollowbody I, so there's less maple than a HBII, but the 57/08s have everything that I felt was missing in the Archtops. The Archtops were too rounded and mellow for the type of music I play, which is funk-rock.
I posted this in another thread, but I'm absolutely psyched about the mod. It makes what is already an extremely versatile guitar into a complete sonic Swiss Army knife.
The best thing about this is that I never, ever used to use the middle pickup switch position. Like ever. Now, being able to have the bridge as a single coil and the neck as a humbucker simultaneously (or vice-versa) is just awesome, especially with overdrive.
Highly recommended.
