I've got a SR-1000 that I bought new just over 20 years ago & has been my main bass for just about everything.
The necks on the SoundGear basses are very slim & have very good access right upto the 24th fret. I've never had that issue with the grub screws that Paul mentions, so it might just be on ones from that era or just the 6 stringers (maybe even restricted to 506s).
The old Ibbys had IBZ C2 pickups, which was made by EMG for Ibanez. The higher end SR basses also have pretty good electronics & I've found the "Power Curve" system can give you a huge range of tones. The newer ones have Bartolini pickups.
I originally bought the bass to play rock & metal (& it did the job just nicely), now I use it in an acoustic folk/country/jazz band & planning on using it for some DnB/Dubstep.
It did start life as a metallic black instrument & just recently turned it into an ash finish (Yes, I stripped the paint off it!). I would like it as a 5 or 6 stringer, but the neck's too narrow to fit another in there.
Anything else you need to know?
