MESA 400+ with Graphic / Parametric Eq???

    Is it possible to bypass the 7-band Mesa 400+ equalizer and use a parametric or graphic equalizer (thinking a Rane PE17 or DEQ 60)? I have a hard time getting a "non-muddy" tone when playing with acoustic guitars (plugged into a small PA) and figured this might be a way to really shape my sound.

    If possible, how does it sound & how doe it work...where do I input from the EQ to the 400+.

    If not possible or this is madness, please let me know! :D

    Thanks for your help!

    If it doesn't have a defeat switch, you can always just set the graphic flat and post-process with your parametric.

    I took a look at the amp last night. No defeat switch, just a effects send & return on the front and back.

    Out of luck?:bawl:
  4. there is a switch next to the graphic eq. that says eq in or eq out. Thats the defeat switch.

    If you mean the eq yes it can be defeated, just as reason bass stated above. If you mean the preamp section, no I don't believe so or at least there is no "switch" to do so.:)

    You'd want to put the eq in the effects loop (effects send and return on the back) and use the effects blend knob to mix it into your signal.

    It should work great, but just using another eq instead of the onboard graphic eq doesn't make too much sense. With all the push-pull bright and boost switches on the 400+ you have plenty of eq capabilities. You might look into a BBE Sonic Maximizer or Aphex Aural Exciter which both do a wonderful job of removing mud from tone.
