Nocaster is correct...

For BL pickups, I use L-280S(N & M), L-280T(N & L), L-490FL, L-450N, L-500R, J-45, P-46, L-250XL

On my set-ups (and some were set-up by Bill when he & Becky were still in PA), the High E - Low E slant is more pronounced on the L-280s, L-490 (now the L-609), L-250; for the (bass-style) J-45, and even the P-46 Precision bass style pickup I have slanted (G - Low E) for the bass pickups. The only ones I see maybe a little less of a treble to bass slant on are the L450 (now the L600) & L500.
