I bought a G&L "Tribute" L2500 a few months ago. I've played bass since I was 13, which I started out learning with a cheap department-store brand. I held on through a semester of college jazz band before I finally had to accept that being a great jazz bassist was NOT something I was cut out for, and I couldn't ever afford a decent instrument and related gear.
I still don't have a decent amp, though when I need to play out on bass I use a keyboard amp. The L2500 has active pu's, so I don't have to worry too much about the preamp having enough juice to get me a decent bass sound. I can also plug into my laptop if I really need an "amped" bass tone and not have to worry about compromising on power. I'd love to have a "real" bass amp, but I don't play bass enough nor do I have the money to justify getting one.
But I will say I love my new bass. The G&L L2500 is so full of bass tones it's redonkulous. It has switchable passive/active/active+treble boost, parallel/serial, and (of course) 3-way pickup switching. The only thing keeping it from being absolutely perfect would be a switch to toggle between single-coil and humbucker so you could get a true J-bass sound.
The electric bass is amazingly underused as a solo instrument. My bass is excellent for what I use it for, which is mostly just for making demos or recording tracks I plan to use live. But what I really love about basses in general is just how well they can really "sing" in ways a 6-string electric just can't. It doesn't always have to be about shaking the foundations of the house or blowing out windows. I always like to hear tapping technique on bass such that it has a sort of classical guitar feel to it. To me that can be really soothing, and I'll pick mine up from time to time when I'm intensely UNinspired and just improvise melodies higher up on the neck. If I really want to mellow out, I'll throw in a little chorus, delay, and 'verb and just drift away...
