I played an L2500 not long ago. The electronics tickled me, but the B string left something to be desired, but that could have been a factor of things like dead strings on a used instrument, etc. My experience with SR5s, on the other hand, has been universally positive - so that's something to consider. I suppose I wanted to get away from the MM sound, as I frequently gig with my SR4H, and while I love it, I think I'm looking fora different palate. I'd love to have the opportunity to play a few more G&L's - my only experience with them has been with a consignment instrument.
I had a G&L 2500, and that bass always sounded too aggressive for me. I suppose in a loud rock setting it would probably be great, but it was too "in your face" for the more subdued music I play, no matter how I tweaked the many little switches and knobs.
I had a Lakland Skyline 55-02 which I had to sell after my divorce. The craftsmanship was absolutely impeccable. But I never got comfortable with it. It sat in the case a lot.
I'd reccommend a SR5 with either the HS or HH pickup configuration... lots of different tones in there, and you could even get a really slick limited edition in your price range (2007's in that gorgeous blue sparkle sunburst still available at Bass Central, as are 2008's in Sierra Gold with gold hardware... both stunning).
Same ol' story huh???
