cheers again steve,i dont know anything about pickups,but when the bass had no output after i tried to raise the pickup with the adjuster screws, i discovered that the two solder joints had come away,and also the top of the pickup came away in my hand(the polepiece part),. i tried to put the wire back on but could,nt get it to work.
I dont have the bass right now as its in the shop, or i could have posted some pics(i should have done that in the first place). its hard to explain, but if you look at any pictures on the net of the 51 reissue tele bass ,and that kind of pickup,
you may be able to see what i mean. cheers again for your help.
