I put a set of Bare Knuckle '63 veneers in my Silo Special and I'm very happy with them. Make sure to ask for a RWRP middle pickup if you do. The silent circuit works perfectly with these pickups as well. Check them out at the Bare Knuckle Pickups site and you can listen to their very good sounds clips.
I was going top ask about the silent cirtcuit with the other choices you folks have made? Was it an issue? The tech at DiMarzio, said the the original pickups were similar to the 'True Velvet' and regular PAF' hum..(both are vintage output)...I am considering the DiMarzio AT-1 Hum, Duncan Custom, EMG 89, Bare Knuckle and Fralin (whos right here in my town)..will let you know..Thanks again!
