Lumberg jacks for audio and for power are my fave too! They save a surprising amount of space, as well as being sturdy.
For knobs, I suppose it depends on where you are... For those in Europe, Musikding distribute a nice range of special and classy ones.
Sorry for the extra demand, but do you know whether you're going full-on with the Daisy vibrato instead of the fv-1, or will the latter also be made available in due time?
Thanks in advance.
