Many bass-building companies, G&L among them, have taken a lot of stabs at "new and improved" jazz-style basses. Fender itself has tried it. But the fact remains that the bass that Leo designed in the 50s still tops them all in most players' minds. I myself own an MJ-4, and I personally prefer it to any "normal" jazz bass. But most musicians don't like new things. We laud progressive creativity, and yet a 50+ year old Beatles album still makes our top-five list (as well it should, IMO). In short, we don't want a better-sounding better-looking jazz-style bass. We want a Jazz Bass. I'd be willing to bet that G&L's sales would show that they've sold more JBs than all their other progressive jazz basses combined. Those would be the SB-2 (when it used to have two single coil MFDs), the El Toro, the JB-2, the MJ-4 (and 5), and maybe some others that have drifted into obscurity due to lack of sales. This fact is possibly influencing G&L's thinking when it comes to the MFD-equipped JB. They have to be wondering just how well it will sell because it sure won't sound like a Jazz Bass. This is just my opinion. We all have them, just like we all have...well...you know.
