You should play one, seriously it’s a revelation. When the short scale revolution started to get some traction, I thought I should investigate and I went out to they a bunch. The JMJ was easily the best I tried of the mainstream manufacturers, with only Viv Wilcock’s output being another contender (price and availability ruling them out, sadly). The Vinteras aren’t bad at all but, despite a very similar spec, the JMJ is much better. The small body makes the slab construction perfect (for me), with the upper bout being spot on as a forearm rest. Upper fret access is restricted, but not as much as you’d think and I’m not up that end a whole bunch anyway. Up against P basses, it blows them away as it’s just… more. Kudos to,Seymour Duncan for the pickup and Fender for the neck shape. The relicing is a bit caveman with a couple of tools like, but then you don’t care if you bash it. Despite having 2 custom basses built to my spec and great instruments that are, the JMJ is my go to and has been for as long as I’ve owned it, 3 and a half years.
