Hello! I was digging through specs in Thunderbirds, which is something I hadn't paid much attention to. I went from a Thunderbird goth to a Thunderbird Pro V recently. One thing I wasn't a fan of in my goth was the huge neck. I also play J basses so they always seemed big in comparison. When I bought the Pro V I didn't check the neck specs but was very positively surprised to see that, even though the nut width is big because it is a 5 string, it is comparatively smaller than I expected it to be based on my goth. The flatness of the slimtaper neck is my favorite aspect of my Pro V.
I play mostly metal, funk, psychedelic rock and math rock, and I feel shorter spacing gives me a lot more speed when playing, which is important for these genres.
Most of you have the more "traditional" 1.73" neck, it seems. Aside from the anatomy (big hands, big neck) argument, what other advantages do you feel this girthy neck brings to the table?
