Sweet look tight sound - Reviews Mesa Boogie M3 Carbine Combo

This bass amp is a a tone monster. Even though it is only a small 1x12 combo the tone is enormous. This little amp coupled with the FET power output is just tonal bliss. You get the great build quality from Mesa and out that towards a bass amp that has a tone that will fill the air.

Even though it looks small the ability for it to play large venues is easy with the line out option. You can run a line signal out of this amp into the PA of a venue that you are playing where you might need a bit more power to shake the walls correctly.

Let me start with saying how much I love the tone of the carbine bass amps from Mesa Boogie. They has such a pure and sonic character to them that makes the bass lines jump out of the mix rather than hanging back an letting the guitar playing take all the glory. These amps have such a warm tone thick it great harmonics and subtle gain. You can go anywhere and feel strong about the tone you are getting with these amps.


At new this combo comes in at around $1250, which isn't a bad price for a solid built high quality bass amp combo. This head though slim in features pacts quite an enormous tone and drive.

I would buy this amp if I ever lost or got my other amp stolen. I would recommend this bass amp to any bass player who needs a no nonsense simple tones of tone bass amp. Not a lot of features but just tone for days.
