Hey Mark-
   I had the same problem with my tone control; it had no effect.  I looked for a replacement, but couldn't find the right pot (with a 2-inch shaft) locally.  Using needle-nose pliers, I pried the control apart, and found some built-up gunk on the wiper.  After cleaning, buffing & re-tensioning the wiper, and cleaning the carbon pot surface, I carefully re-assembled it.  It now works fine (so far).
   You have to be careful when prying up the retention tabs on the pot housing.  They may only survive one bending cycle before breaking.  And, not all pots can disassembled to the point of repair.  Sealed pots work better, and mine is not sealed (so it will probably fail again).
    I don't have the info at hand, but I believe the original pot is a 25K ohm audio-taper.  I do remember reading in this forum that some have substituted a 10K pot, and it gave them a bit more control of the tone effect over the full travel of the knob (at the expense of loosing a little of the top-end).  10K pots are easier to find.
 
    Good luck.  My best-

The tone control doesn't seem to make much difference to the sound on my M400, which is so bright as to be positively incandescent. Is this a fault on my machine or a difference between the Mark VI and the M400?

3 Violins on the MK VI sound very bright with the tone control at 10.
(Especially through a good keyboard amp or studio monitor). I
usually set the tone control at 3 or 4. I think that the MK VI 3V
tapes are copied from the MK II 3V master tapes, so that will make a
difference too.

Whatever the case, ya gotta press the right keys at the right time or
it will sound like shit.
