Very interesting thread I am torn between the JMJ and the Vintera.
I would get a blue Vintera and stick a tug bar on it. I've seen one JMJ in the flesh and I didn't like the faux wear on it. Saying that, I was weirded out at that point in time because the JMJ was the only accurate Mustang out there at the time with a Fender logo on the headstock, and it had a weird tanline on the pickguard where the tug bar was originally placed on JMJ's personal bass. Plus, it only came in one colour. Nice to copy JMJ's original bass to that level of detail, but I was still surprised!
I'm in the process of buying a fiesta red Vintera Mustang! I'm going to sell my warhorse white PJ Mustang to fund this purchase.
Upon reflection... the PJ Mustang is a great bass. It takes standard pickups, and I think I had four different PJ pickup setups through my bass. I shielded it with copper shielding, stuck a Fender Badass II-style bridge on there, replaced the electronics with CTS and Switchcraft components, and turned it into a solid little gigging bass. The 3-way switch always bothered me, and I never had any real use for the solo'd J pickup.
The Vintera is the bass I would have bought a couple of years ago if it had existed. It is a shame they don't make the Vinteras in olympic white, but I've always wanted a fiesta red Fender of some marque, so this will do!
We are very lucky in the Mustang club, to be honest. When I first went hunting for a Mustang bass my only options were to find a vintage original Fender or a used CIJ reissue. The CIJs had been out of production, or at least not shipped to the UK, for quite some time. The used price of these was pretty all over the map, and I encountered several with P-bass pickups hacked in or bad finish damage.
I bought a used CIJ Mustang and it arrived with the neck off, in a box barely bigger than a shoe box. This was how I joined the Mustang club!
We now have the Vintera, American Performer, PJ, JMJ and Squier CV Mustangs to contend with. You have varying degrees of historic accuracy, and the PJs are out in a whole range of finished through CME.
The only thing missing is a true blue MIA Fender Mustang bass with one pickup and the original-style bridge.
