I play L-2500s (one fretted, one fretless). They have great feel, good build quality, and the "cut through" factor is the best of any bass I have ever played(that includes several much more expensive pieces).
The L-2000/2500 are called "the Swiss Army knife of basses" and I find that to be true. I can quickly dial in any sort of tone that I want. You can get good approximations of P's, J's, 'rays, Rick's, Wals, etc. (but I doubt that I could pull off a convincing Hofner sound)

NO, it will not sound 100% like any of those that I mentioned, but will do ALL of them with a high degree of accuracy while having its own G&L character. It's hard to find another bass that has such a high level of versatility.
For about a year and a half, I was playing a Fender American Deluxe Jazz V as my primary instrument. While I liked the sound of the bass by itself, I always found it getting lost when playing with my band. I sold the Fender and went on a shopping quest for a new primary bass. I went in with a self-imposed spending limit of $2500. The instruments I "auditioned" included:
Lakland
Sadowsky Metro series
Fender
Mike Lull
Warwick
Music Man
G&L
After spending nearly a month playing these brands at local dealers, I kept finding that the instrument which was really speaking to me was the L-2500. It then became a question of finding the one that I wanted in terms of finish, etc. Another month of scouring numerous G&L dealers and I found this one:
This bass was part of the Summer NAMM display that the G&L folks did. The NAMM instruments were then sold to Nitro Tone, a Boston area G&L dealer. I was able to get them to a price that I thought was reasonable and bought this bass in late August. It is one of the best feeling basses I have ever played and has killer tone(s). I never get lost in the mix anymore. With both pickups on, the B string makes furniture fly across the room.
Go somewhere that you can play a G&L. I really suggest that you try one of the double-humbucker models(L-2000,ASAT, or L-2500). Make sure that you spend enough time to get a feel for what the controls really do. Remember, the tone controls are cut-only, and try the various switch settings. You will find a lot of familiar tones as well as some that you wouldn't expect from a bass.
You might find a G&L to be a perfect companion to your Bongo....or, at the risk of sacrilege, a perfect replacement for it.
