It's my 40th birthday today, and my sweet amazing wife ordered me a Fender Standard Jazz Fretless! It's backordered from Musician's Friend, so I should get it in a week or two. Couple questions about them... 1. It seems the electronics have been upgraded recently. Anyone have any details on the differences, and when the changes took effect? Anyone have experience between new and older ones? 2. How is the quality control? It looks like they are using alder now instead of basswood. Are they all generally the same, or are there some huge dogs and some winners? In other words, in this case, would it be worth checking between 3 or 4 in a store, or just being cool with what comes via UPS. For the record, she'd be totally fine with me just buying in a store, or going through a different place like Bass Central or something. 3. Any tips on setting them up? I'm pretty good at setting up fretted basses for nice low action, but I imagine there are different setup issues to get the growl. 4. What upgrades to people generally do to electronics if I was so inclined? Thanks!
