Geoff started Modulus Graphite back in the 80's and his current basses are favorites of mine.
I've owned Quantum's / Q5's and prefer the slightly wider fingerboard of the Gould's.
Geoff's latest version of his graphite necks are nice and thin with a slick, satin finish.
In fact, if I do happen upon a cheap-enough Quantum, I'd like to put one of Geoff's necks on it just to have a P-type / Gould hybrid (now where did my lotto scratchers go...)
I attached a pic of one of my newest members to my stable (nicknamed "Bullseye" after the horse in Toy Story) below.
