Does anyone know what brand and/or model this bass is?

My good friend needs to liquidate his bass collection due to health and I cannot find anything on this bass. It is similar to the Adam Clayton sparkle bass, but it is not. It says made in USA and the headstock has an M logo on it. I cannot find this logo anywhere. Does anyone know what this is?

Maruszczyk, it’s not made in the USA that’s just where the tuners are made.

They make gorgeous custom basses, BTW, that may be a very high end bass.

Reverb listing

This one sold for $1,700. Not sure when that was, though.
