I own a squier II precision,and it's a pretty awesome bass. the squier II's were very strange and inconsistent. some had alder bodies,some had plywood bodies(Like mine). some had fender tuners,some had gotoh style tuners. the general consensus is that MIC<MIK<MIJ
Mine is repainted metallic flake green and has one of the best necks I've ever played on a P. it's a sweet bass,but I don't know why they called them squier 2,then went back to one,that just doesn't make sense.
basically,the affinity is one of the worst made and best selling basses ever made by fender,though I'm sure they are getting better,and the squier 2 is a better made instrument made in a better asian country. squier 2's are strange instruments,and they have a 2 in their name for no reason.
