I've been looking all over for you guys. Just checked all the threads, didn't see this addressed: Has anybody found any secrets for minimizing or eliminating the dead spot around C# on the G string? Here are some things I can eliminate: 1 scale, at least 32"-35" 2 fingerboard and neck wood, at least maple, mahogany, wenge, rosewoods, ebony, pau ferro and phenolic 3 one or two trussrods, single or double action 4 bolt on, set neck, neck through construction 5 straight or tilted headstock My observations have been that a good bass has it most noticeably at the C#, getting better very quickly in either direction, a bad bass is fuzzy from A to E. My Hohner Steinberger knockoff seems to have it more an octave up, but chopping off all the extra wood on a P bass headstock focused the dead spot but didn't eliminate it or change its pitch. I believe my upright even has a smidgen of it. A stiff neck with a chunky shape seems to be the best answer but it still seems like there should be a way around it. I think the fundamental is about 155 Hz, no? Seems like the fundamental and first harmonic die off quickly but the higher harmonics continue to sustain. Enlighten me, oh gurus.
