To my eye, they look BORING.
Every time I see a G&L, it's a natural finish on plain looking wood with a bunch of knobs and switches on the face. In short, it looks like somebody built it in their garage.
Compare that to Fenders and Stingrays that have muscle-car looks on top of a more manageable control scheme, and it's just no contest.
Then I guess you haven't seen mine. I do own a plain wood Tribby but the other two USA are blueburst. Definitely NOT plain or looking like built in a garage!
And the very features Georgestrings hates (chunky neck, "eye poker headstock", etc.) are the very features that I LOVE about mine. I HATE that profile on my Fender JAzz neck. (love the precision profile, however). G&L workmanship has no problems. SX these are NOT. Fender in my experience will give you a MUCH greater chance of scoring a dud.
But I can understand the problem. Basses are played by musicians and among them there is this faction that just absolutely FREAKS when they see more than a volume control and tone control on a bass. All those switches on an L2X00? Who can understand what they do? And it's WORSE than that. Those tone controls are PASSIVE! They work strange. A person actually has to LEARN how to use them. Who wants that? And those pickups. Cripes, they can be SO aggressive. They sound nothing like a Fender. Who wants that? Who wants ANY of this folderol?
Well, me, of course. Because I love total choices. I LOVE that these basses can be as aggressive as I ask them to be. I absolutely LOVE the tone, the neck, the look, the feel... ALL of it EXCEPT the fact that I can't buy one with 6 strings that isn't a guitar.
So oddly "Leo's last bass" is nothing like his first bass which so many are still in love with. But personally I find it no less valid. So much so that I've actually wired a couple of my other basses with "Leo's last circuit" which is the wiring in G&L L2X00 basses...yes, all those knobs and switches. Personally I find a G&L as big a classic as the Jazz, the P-bass, and the Stingray... provided you don't suffer from knobophobia.
I'm sure it's no surprise to anyone that my G&Ls are my main 5er axes.
