    Hi everyone, i need a nice small combo for some "light" gigs with the upright and why not, with the electric bass.

    I was looking for the MB150 (second hand) s or e, doesn't matter.

    I noticed that there are different series of this combo. Do you know the differences between the series?

    I found this one (2nd series???)


    (i've also found a MB200, is it better than the MB150?)

    thanks and ciao

    Your older one looks axactly like mine which I bought new 6 months ago. I'm not positive but I think the different series just represent some upgrades. The brand new one I think is designed to run cooler and I think a little quieter (although preamp noise was already pretty low). Mine is the S model combo and I've compared it with an older one in a store. I can't hear any difference in sound between mine and the older series now that the speaker in mine has loosened up from being played a while.

    The 200 is an older amp, that predated the 150. I believe it has less power and slightly less bass response. On my new one there is a switch to give you the option of getting the MB200 tone.

    It's a great little amp, the 150. In fact, I was just practicing for the last hour and really enjoying the sound. My P bass sounded just like a P bass should and my Artcore had its own distinctive sound, all without changing the tone controls.
  3. The original 'series I' from 15+ years ago is quite different (diffent amp design, etc.). The Series III seems to be just a minor tweak on the Series II. As long as the look of the amp is like your picture (i.e., not a series I), then you are good to go.
