Anyone here know of any good ones? I know they're out there I would like to narrow down my search.
My current dilema is with my 32" build planning - the fingerboard will be in the neighborhood of 20 to 21 inches and the dual action truss rods are available standard at 18" and 24". So an 18" rod, installed for headstock adjustment, will have about an extra inch + of unsupported area at the heel. Doesn't seem like a problem but then again I've not done this before.
