Re: 59 or Anico Pro II
I like both pickups. The Alnico II Pro is very warm sounding, but it does not have outrageous mids, like the JB. The bottom end, as well as the high end is not as defined as in the '59. For fat, singing leads, I would go for the A2 Pro. For a more versatile pickup that will do both ryhthm and leads well, I would go with the 59. Personally, i like to play ryhthm on the bridge or middle positions, and I like the neck for leads.
What type of sound are you looking for?
