G&L vs. MM is a battle that will rage for years, but, as you can tell by my handle, I am clearly biased. Can a MM sound like a P, a J, a Rick, hell, even a Dan-o? Ever heard a StingRay pickup in passive?

.
MM's have their own thing, and are slap-tastic basses, but G&L can NOT be matched for versatility. A StingRay can cut through the mix, but an L-2000 DRIVES THE BUS. No other production bass can match what MFD pickups can do. I've owned both new and vintage MM's and G&L's, and I can tell you through actual gig experience, nothing propels a band like a G&L.
Tribbys have the same Fullerton made MFD pickups, and as far as a comparison to Squier, the Trib's are more in-line with Lakland's Skyline series, where there is obvious quality control.
G&L's are also ridiculously cheap for used on FleaBay, even for vintage. An American L-2000 can go for as low as $550, and vintage G&L's (1980-1982) are insanely low.
I've owned and gigged over 100 basses over the last 30 years, and my #1 go-to is a G&L. I just wish I would have found out about them sooner- I coulda saved a huge pile of money

Now, go get one.
