this also does not turn up anything of real use... :( especially if you then go
to
http://lilypond.org/doc/v2.0/Documentation/user/out-www/lilypond-internals/lilypond-internals.html
and Ctrl-F for Equalizer it finds two matches:

    [Under Context-Properties]
    instrumentEqualizer (procedure)
        [DOCUMENT-ME]

    [Under Dynamic_performer]
    instrumentEqualizer (procedure)
        [DOCUMENT-ME] 

The problem Will is experiencing is due to a typo in $LILYROOT/scm/midi.scm :

lines 40 -- 57: 
<<<
;; define factors of total volume of minimum and maximum volume
(define-public instrument-equalizer-alist '())
(set! instrument-equalizer-alist
      (append
       '(
   ("flute" . (0 . 0.07)) <<===
   ("oboe" . (0 . 0.7))
   ("clarinet" . (0 . 0.7))
   ("bassoon" . (0 . 0.6))
   ("french horn" . (0.1 . 0.7))
   ("trumpet" . (0.1 . 0.8))
   ("timpani" . (0.2 . 0.9))
   ("violin" . (0.2 . 1.0))
   ("viola" . (0.1 . 0.7))
   ("cello" . (0.2 . 0.8))
   ("contrabass" . (0.2 . 0.8))
   )
       instrument-equalizer-alist))
>>>

the offending line is line 45, marked w/"<<==="...

Jan: i think this is a bug... :)

Will: if you change this entry to 0.7 it should then be ok. you could probably
(no guarantee) pass a similar construct to Voice.instrumentEqualizer to obtain
the same effect if in futute you wish to tone voices down relatively in relation
to others.
