Mesa Boogie Bass 400+ Wiring?

  1. Ok, so I have been playing my M/B Bass 400+ for about 4 years now, and I still havent figured out how this thing is wired!

    Is it gain-tonecontrol-EQ-Master, or is it gain-tonecontrol-Master-EQ, or maybe gain-EQ-Tonecontrol-Master? Is the effectsloop before or after the EQ? This beast looks so simple and straightforward to the eye.. but apparently it fooled me! :) But I love its tone, just have to get my self to the gym in order to get it on tour! ;) (or get roadies!!)

    Can anyone help me with this wiring issue?

    If memory serves me correctly, it's gain, tone controls, graphic EQ, FX loop, master.
