I hope David doesn't mind that this thread is going further and further away from Barber pedals :p

I had the same problem as you sometime back, and settled for Texas Specials in the neck and middle positions, and a Seymour Duncan Lil '59 in the bridge position. Check out the offerings from Duncan, Dimarzio and the like, or companies like BG Pickups, WCR, Highorder etc. if you want to go boutique. Read some reviews, listen to audio clips, watch some demos on YouTube, and you should be all set.
