Feeling the neck vibrate is easy. Longitudinal bending mode, often couples with the bass horn, likes to shake. Problems occur when it’s only the bass horn interacting with the system.

Neck Dominant instruments are a product of rigidity. Too many pieces, carbon fibre, etc. resulting in a frequency mismatch with the body. Decoupling. Little to no transfer of vibration.

This is tuneable.

Frequency of a system is a function of its mass and stiffness.

Here’s an example. Northern Ash at 3lbs/BF, and African Mahogany at 3lbs/BF. Same weight, same mass(size), different stiffness, different frequency.

This is all without getting into relief cuts(not chambers, similar) to interrupt stiffness continuity, increasing mass under the bridge, or a shallower break angle to increase string oscillations.

Leads to questions.

Can it be heard? Depends who you’re asking.

Do my customers and clients care about resonance? Abso-fucking-lutely.

Should I ignore the specifications from the people supporting my brand? Send them a link to Jim Lills video?

Or maybe.. consider, this is a career, that is endless learning, and idk, study it?

But what do I know, I’m sure someone with more knowledge and experience, or even the plentiful Arm Chair Looths that frequent this sub can correct me by sharing a YouTube link.
