DB finish

Hello Guys,

Last week I finally had my first DB lesson! It is hard, but I am already lovin it.
In a previous thread, I have been suggested the folding bass, since I have to move a lot over Europe this year.

They offer a gloss finish, a "satin" finish, and maybe custom ones. My teacher told me that it can affect the sound a lot. Any hint about that? Any opinion on the folding bass is also welcome.
