Okay, long story short: I have a Fender Jazz made in Japan that's maybe 10 years old. I feel the tone is not what it should be. I was thinking about what to get (I was seconds from diving into a new Rickenbacker ), but decided to get a Yamaha 424 based on reviews and the price . First thing I noticed is the Yamaha is much MUCH hotter. Also, the pickups seem to be a lot more touchy. Notes jump out more. I suppose that would just taking getting used to, maybe that's better. (Looking at a waveform, the Yamaha has all sorts of peaks whereas playing the same thing on the Fender the same way, it's quite smooth, wouldn't even need a compressor). The Yamaha also has a deeper tone on the low end. But the Fender is a little more up front, more low mid. So I'm wondering if maybe just new pickups on the Fender would "fix" it. Make it deeper, more lively, more like a great Jazz instead of a sort of lifeless one. Or is there more to it than that? Thanks very much to you all, I've asked a few questions here over the past months, and I really appreciate your expertise.
