From what I understand, this is pretty much the same gig bag as the FEJ610, which is a little bit larger, so as to fit Jaguars and Jazzmasters (hence the extra letter “J” in the latter's product code). The main difference I noticed (other than the size of course) is that the inside of the front pocket is red on this one, whereas it is black on the J version. I would not dare say that the quality is perfect, but for the price, this gig bag is surprisingly nice. The zipper is much better quality than on some other similarly priced gig bags, and the shoulder straps are very comfortable. The only downside is that the pocket does not accomodate an A4-size notebook.
