The Squier 'Standard' Jazz bass is no longer made if you were referring to the model, but I take it that you meant 'in general' ... Squier Jazz basses are going to vary greatly on a case by case basis between both models, and individual basses ... I have a black/maple/blocks Squier Jazz that is right at 7 lbs, but I went through several to find it ... close to 9# was not uncommon ... I have also had Squier Standards, VM, CV's that were up close to 10 lbs ... the lightest VM I have had was about 6.7#'s, the lightest CV 60's Jazz I have seen is mid to high 8# range, most are low to mid 9# range ... MIM Standards vary greatly as well, depending on era .. it was not uncommon to find one over 10# back several years, the current '08+ offerings tend to be more consistent in the high 8-low 9's ... I have a 7.9# MIM Standard Jazz, but again, I went through several before it came along, and it actually is a combination of two basses lighter components ...
... case by case is the best rule ... but in general, you
can find a Squier Jazz that will be substantially lower in weight than a MIM Standard, but then you will be using generally a lighter, softer body wood, smaller pots, etc ... weight can be a component trade off as well ...
Edit to add: .. if buying a used bass, consider taking the weight given by seller with a grain of salt ... weighing methods and scales vary greatly, and only one used for commercial trade and calibrated can be trusted as accurate ... I have purchased basses that were reported in the 7# range show up in mid-high 8#'s ... one bass was 2 lbs heavier than quoted by seller, and the low weight was the entire reason for purchase ...
