Yeah, I cut the board I ordered into 4 stripes, rotated them for 90 degrees and glued back together with purpleheart veneer in between, to get the core/neck part.

I really wanna build one almost completely from bamboo (with various veneers to get some accents/lines in) but it's really hard to source boards now. Meh... but yeah, who would have thought that "tonegrass" would become a term someday haha.
