I just bought an Ibanez JTK3 (http://www.ibanez.com/ElectricGuitars/model-JTK30). It has Ibanez soap bar pickups, which are apparently supposed to be comparable to p90s. I'm thinking that I would like to upgrade the pups at some point. Any advice on good pickups to consider? I want kind of a vintage blues-rock sound (i.e. Hendrix, The Black Keys, etc.) Thanks!
