It's all good...and I can never play with most standard issue nut depths and have to cut a little, but I'm really light handed...looks like I'm whacking the snot outta stuff when I play but I'm light handed and my nut slot depth is generally about the thickness of 2-3 business cards string height between first fret and string, if that, probably closer to 2. Any higher and it feels really high to me, but every one is different. Im actually looking at culling the herd Monday and offing one of my white Jazz basses for a Geddy, a 70's Classic Jazz or another Jaguar Deluxe...maybe the Geddy will win.
No I meant is it worth more selling individual parts or the bass as a whole was my question.
With that in mind, I think the OP needs a new amp.
I never usually go into amps...I have my Sansamp Bass Driver DI that goes into the main system. My practice amp is actually a practice guitar amp ( Heaven forbid!!!) but I don't see the point of getting a bass practice amp. My room is way too small to fit an amp bigger than a practice one.

How much are you turning the truss rod by? Turning it too much will seriously get it out of whack I know because I've had this same problem and I just did a neck reset, and since my bass was very sensitive to set ups I had to do a very tedious setup and turn maybe even 1/8 of a turn every 2 minutes. Every month I usually do. And letting the wood rest is always good.
1/8 is about how much I can do. There's a lot of resistance as I tighten it so that's about how much I can do whether I like it or not.
