I have a couple of questions in relation to AVRI pickups and also Fender 57/62 pickups people can buy from Fender dealers. My first question is in relation to black bottom staggered pole 'vintage' pickups that were factory installed in both 'Fullerton' 57 and 62 reissues between 1982 and 1984. I am aware of red bottom and grey bottoms preceding the black bottoms and have stamped 82 grey bottoms in one of my 57 reissues. At what stage (year) did Fender stop using those exact pickups in their AVRI Stratocasters ? For example I have here a set of vintage USA black bottoms with staggered poles that are identical in appearance to the set in my 1982 JV ST62-115, same formvar coating and other details. I found them last week after recalling I had them in a 1989 MIJ ST57-70 but swapped them out for Texas Specials. The 1989 57 reissue came with USA vintage pickups just to clarify. My second question is when did Fender first start marketing their 57/62 pickups and were they ever installed in AVRI Stratocasters ?
