Can somebody tell me where I can get different colors of knobs for my Series I?
 
I like would like to find some brown switch knobs or peanut-butter/brown/cream/ colored tone & volume top-hat contols, and the same for my selection pickup switches.

Roger at THG Knobs has made knobs for lots of folks around here.  He did knobs on two of my guitars.  Whatever you want, size, shape, woods, inlays, reasonable prices (I think I paid something like $16 per knob) and a quick turnaround (I think it was 2-3 weeks).  Check him out.
 
Bill, tgo

I have THG knobs on all my Alembics. Price varies depending on how elaborate you get.

I had this color in mind for the knobs. Don't this picture look like a candy carmel apple  
 
The knobs are beautiful here on this luck person's alembic.

Those are THG knobs, custom made out of some species wood. My guess would be cherry, like the top.
