The M-2000s are useful basses. They’re pretty much like any of a number of active basses on the market: Volume, boost or cut B/M/T, and pan, while being full time active. So nothing special from the perspective of the larger bass playing realm. Just a typical “blank slate” active bass that you can dial in a lot of tones on.
But it was definitely a departure toward the mainstream for G&L. The L series was never “really” active. It’s a fundamentally passive design, just with an optional boost. It’s a versatile bass, but definitely has more of its own inherent tonal character, and does have some limits in terms of controllability (2-band only, cut only e.q. controls, no variable pickup blending). The M has little inherent character of its own, but because of this “flat” character combined with its more capable controls, it can easily be made to sound like practically anything, just using the onboard knobs.
So, the M-2000 was a good bass, but it had a huge amount of direct competition in the marketplace, and it came along during a period of declining build quality and increasing prices at G&L. There were other basses out there that could do the same thing just as well, and that were just as well built (or better), for about the same money…and very few people specifically seek out G&L to the point at which they’d choose it over the competition just because of its brand name. Bottom line: it just didn’t sell.
This bass looks like one that was on Reverb for months earlier this year, located in Avondale, PA. I really wanted to buy it, but other things kept calling to me first. It was down to $800 at one point, and I should have bit. If your bass is CLF065392, with the notable feature being an old school 7 1/2” radius, it’s the same bass. It was assembled and set up in the factory by my friend and sometimes bandmate.
