For my 1983 Emmons Push Pull, with 8 pedals and 9 knee levers
The E9th Neck (subject to change)
Terms used and definitions:
The table below lists the strings, vertically, with #1 = F# (the front string) and #10 = B (the back string), on the E9 neck (front neck). The floor-pedals are listed from left to right, with P-1 as the outside, left pedal. The knee levers are also left to right, where LKL = "Left Knee Left", LKR = "Left Knee Right", RKL = "Right Knee Left" and RKR = "Right Knee Right". "Back" means the knee lever to the back of the body; "front" means to the front of the body and "up" means push the lever up. The term + means raise (sharp) one fret; ++ means raise two frets; - means lower (flat) one fret; and - - means lower two frets.
The pedal numbering is from the left to the right (P4 thru P8), with P8 being the last one on the right end of the guitar. The knee levers for use on the C6th neck only are labeled as (LKL, not yet installed), LKR and LKup. One activates to the right, the other moves up. The right side knee levers are shared with both necks. I am still trying different arrangements for these knee levers.
As was explained in the E9th section, the pluses (+) and minuses (-) mean sharp and flat, one per fret (semi-tone).
