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....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.
