As Hank was saying you can keep the bar in one position and have access to the scale of say C and it's chords in 5 inversions.

Then by pushing two pedals you have the F scale and chords in three inversions.

You can press one pedal and engage a knee lever for the G Major scale and chords,

Other pedal/Knee lever comb. will get Amin Dmin or Emin
Other combos gives you different dim and aug chords.

There are several other positions on the fret board with other pedal/knee combos that gives you similar results.

You can also get these scales by moving thr bar up and down the fret board.

These examples are for the E9th tuning. There are a whole different set for the C6th tuning.

If you have any other questions fire away and I'll do my best.
