Thanks, Pete. It is a 35. The neck is a good bit chunkier than the Modulus, and the string spacing is a tad wider. Switching to the Alembic was no problem, however, and after playing it exclusively and extensively for the past 4 days, the Modulus felt almost petite when I picked it up today. I haven't got the action exactly where I want it quite yet. The combination of going from being a super-low EADGC back to a moderate-relief BEADG and moving from Texas to Georgia seems to have the neck a little confused. It is actually stiffer than the Modulus, though, judging from the amount of force it takes to flex it by hand. I'm sure it'll settle in nicely.
The thing that impresses me most versus the Modulus is the sensitivity of the controls. The blend actually blends over it's entire range rather than the first 1/8th of a turn, and the smallest turn of a filter produces an audible result. Also, the ability to change the character of the blends is amazing. I can get a growly topend from the neck blended with low-mid punch from the bridge, or I can go for whoomp from the neck and sparkle from the bridge. The palette is so much more complex.
FWIW, my custom will have a neck slightly smaller than the Modulus, by about the same degree as this one is larger. Should be amazing!
