This set has the best ever~Killer Playability! 
(1)-6.7k Bridge!  Hot enough to push the amp a little better, but never overdoes it!!! (1) 1954' Neck Pickup 6.6k its the best neck here!

1951's AlNiCo 3 Bridge & 1954 Neck tone- This set great for rock,  blues , country, JAzz and Improv! _  Hot Country guitar solos,( Hello Danny Gatton!)  Hot Dirty Blues (Hello Albert Collins), and Hard Classic Rock ( Hello Led Zep and ZZ) ALL this in ONE-Set has created a huge demand for this 1951 Era modified Bakelite- set. This set will get you there and also to places you have never been! 

Here's the Mods:
The Neck is my normal 1954 model, 6.3k is AlNiCo 5 nickel-silver(chrome plated) cover
The Bridge is fat and full yet cutting.  Its a 6.7k AlNiCo 3 flat pole.

(Artists currently using this set include Kirk "Eli" Fletcher, Brofey Dale
 Rick Holmstrom, King Zapada=Gary Clark Jr. band, ) ( this set has been his main stay in the butterscotch T-style guitar)
& there has been many more top players that have made the switch to this set over the last 19-years!)
