    i'm wondering if someone can tell me what flat is on the mesa bass 400. i have the older bass 400 and not the 400+ if it makes a difference. Thanks,

    everything on 5 or so i've been told is flat.

    I drive mine after 5 to achieve desired sounds bro, work it! ;)
  3. Hi!
    I've read that being based on the old Fender tone stack, Mids at 10, and bass & treb at around 1 or 2 is flat on the boogie (with no pull shifts engaged).
    I could be wrong though...

    If memory serves me right, the bass and treble controls are active, while the mid is passive. If that's the case, you set the bass and treble at 5 and the mid at 10 to achieve a "flat" EQ.

    That being said, this amp is naturally far from flat sounding. EQ with your ears, not with a preconceived notion of what "flat" may be. If it were me, I'd start with everything at 5 and work from there.

    would that also be the same for my old Fender Bassman 135?
