Alnico 5 magnets. Carefully wound to create a very warm and full tone at the neck with nice round bass. This will bring much needed life to your guitar! I offer chrome or gold. The bridge produces even more separation than my Vintage Country Coil's vintage sweet-lap steel like sound. This set is intended for the serious picker who does lots of steel bends, banjo trills, chickin' pickin' etc. NEVER BRITTLE!! Set calibrated for neck/bridge. Made in the old style-I like the sweet sound of the low output pickups of the 50's.
