What features for a smoother sound?

[grandmainger]

I was wondering what features you would select in the building of a mandolin in order for the instrument to have a smooth, jazzy sound, as opposed to a sharper, more woody/bluegrassy bark...

Would you for instance select:
- a particular tonewood
- a certain bridge/nut material
- a special finish (lacquer, varnish, etc)

Anything else?

T-I strings definitely seem to fit your description, as would heavier, more rounded picks.

Also, some people are of the opinion that a heavier finish (like a gloss lacquer) results in a tighter, more focused sound that is better for jazz and blues, Whereas a lighter finish (like a varnish or a lightly applied satin lacquer) results in more raw, woody sound that is better for bluegrass and old-time. I am sure there are exceptions, but I think there is something to that idea.

The builder can adjust the tone while building. Arching (if it's an arch-top), graduation, bracing, wood species etc... everything affects resulting tone.

Those verbal descriptions of tone can be subjective. #With that caveat, I have a Weber Gallatin with the mahogany back. #With the T-I strings mentioned above it has tone similar to what you are describing. #From other comments on this board, an oval soundhole would probably help also.
