I own AND play daily, 2 G&L basses with no intention of making a change or make an addition so take this with a grain of salt: The 2 Brits at Anderton's take on this very question and what do you think are the results? The G&L in contention, I should add, is an Indonesian made G&L vs. 2 US made instruments. Long video I know, but i love these guys.
To be entirely fair, I think they mention at the beginning that the Fenders in this video are Mexicans and the Stingray is Indonesian, but still...
I was as pleasantly surprised as these guys when I tried (and bought) my L-2500 in '99. I had planned a trip to check out the three biggest music stores in Montreal to sample what they had (and upgrade from my awful Squier HM!), but pretty much had my mind set on getting a Stingray. I tried everything: Fender, Ibanez, Yamaha, of course MM, but then I tried the G&L and that was it. I had never heard of the brand before, but the neck felt absolutely perfect to me, the fit and finish was stunning and it could do just about any tone.
