My thoughts on knob sizes / knob placement:


Someone suggested using the standard MOTM knob grid / making the unit 
look like the 480.  DO NOT DO THIS...instead:

Do like Paul suggests and, for the main frequency control, use a 
larger than MOTM size knob.  (Probably a PKES140 which is 1.5" 
diameter at its base.)  Place this single large size knob near the top 
center of the panel.  Use the combination of large tick marks with 
smaller "sub" tick marks for this knob.

Use your normal (small size) knobs for everything else.  Arrange these 
in the space below the single big knob / above the jack field.  Use 
the single set of thinner tick marks on all of these knobs.

Jack placement is fine but maybe center the sine and cosine outputs as 
someone else already suggested.


Here is a rough layout drawing to better illustrate my idea:

The three dots in the triangular arrangement are supposed to be the 
LEDs.  The top LED is clip (positioned just below the gain knob) and 
the left and right LEDs are the sine and cosine, positioned near the 
associated knobs.


In my opinion this layout looks really nice, it is functional / plenty 
of space around the knobs, and you even get to use your stock of 
existing small knobs (with the exception of the one big knob) which 
is, of course, in the tradition of classic frequency shifters.
