[i]To me[/i], the G&Ls are better basses than Stingrays. It's not that I don't love 'rays, I do, but the G&Ls are more versatile, and I find them more comfortable to play. As far as the 'ray HH is concerned, I reckon it's capable of a lot of tones, and is the only bass you'll get [i]that[/i] Stingray tone from, the L2000 will get close, but it's not the same.
I would describe the tone I get from the L2000 as something between a Stingray and a Jazz, but it also does a good Precision impression too if you set the EQ right.
If it's a Stingray tone you like, then it's a Stingray you have to get, but [i]for me[/i], if it's versatility and playablity you want, it has to be the G&L every time.
