Hey.
Wandered in looking for something else....
Noticed the discussion of Modulus necks and what about different body woods.
Just for info I have a Quantum 6 Custom SPi that I got new in 1991 and it has the original no-truss rod neck (never a problem) and a body of mahogany with a cocobolo figured top.
So yes, combining the graphite neck with other woods results in a fabulous warm sound with clarity a plenty. Best bass I've ever had period.
