    Hi anyone, I need help on this one! I am using a Mesa 400+ with 2 x 1x15 cabs and a Fender custom shop 55 bass, but the sound seems muddy all the time, or either booms, I know the eq on the amp is hard to work out. any help on the amp settings? HELP!

    That's a common thing with 400+'s.

    First you want to start with your amp's EQ set flat. Turn off the graphic EQ altogether to start.

    Next, flat on this amp isn't Bass/Mid/Treble set at 5's.

    Flat looks like this:

    Bass= 0
    Mid = 10
    Treble = 0

    In other words, You can only boost bass and treble, and you can only cut or attenuate the mids. Thus, the 400+ is known as a scooped mid bass amp. This is the old Fender Bassman tone stack.

    If you like a more traditional sound, you'll probably want to leave the pull-shifts on the bass & treble knobs in. If you want a more modern punchy sound, then pull those out. You're shifting the band that the knobs effect...the bass up to the low mids and the treble down a bit, closer to the high mids.

    Remember that you CAN get different tones by using the different channels, or using them both together.

    Once you have a sound you like, then use the graphic to tweak the tone a bit or to adjust it to the room/stage you're playing.

    Mine is usually set like this:

    Bass 4 pulled out
    Mid 6
    Treble 6 pulled out

    EQ on....40hz slider cut about half way. 100hz flat, a very slight boost in the mids and treble sliders.

    Channel 2, volume at around 5, master used to control overall volume.

    You can run both togehter with no ill consequences?

    On my Bass 400, I keep the settings on my active bass nearly flat. I find I get way too much boom if I push the EQ's on my bass like I usually do.

    You are correct, sir.

    I tend to run my bass 'in' at about 6 and the treble 'in' at 0, mids right around 6 too. Lately I've been only running channel 2 with the pre around 4 and the Master around 3. Sometimes I use a Y cord and split the signal into both channels.

    Sometimes I push the lows up to 7, but I find I have to push my 1212 a bit harder than normal to get the low end kickin'.


    Keep in mind though, that I play a reggae gig, so my sound is tailored to that sound.

    Yep...one of the nice things about the 400+ is you can tailor it to your sound. I probaby should have mentioned that my settings are for my classic rock gig, with passive basses (Ric and Lakland)

    I used my ABY to Y into both channels/preamps. What a revelation=) The sound turns out super thick and substantially louder without breakup.
