Hi Ed!
I did think of the spacing change - however the expression pedals can be customized for each instrument. The Expression shoes are generally (I/Choir/Positiv) (III/Swell) (IV or II Great or Solo or Echo) or the far right shoe can be also a crescendo jalousie schweller. I have the approprate LED's now to provide for both instances.
The original Haygren configuration is what you see - I used the entire mechanism after restoring it. I am also going to use the potentiometers from my Samson keyboards - I have to figure out exactly how to do that, but since I am now using the original Haygren console base as my base it has the center portion all ready cut out. I can either put the Potentiometers above the pedals or below the hole in the base. Otherwise they will interfere with my computer case which is 22" x 21" x 9.5". I am trying to keep things more streamlined this time.
I will also add retractable wheels for ease of movement plus the whole shebang has to be about 6" higher due to the Haygren Pedalboard size.
