I know some people put paper between the strings to get some sort of rhythmic/percussive effect, but I don't know how it sounds.
(Slightly outdated) Electronic and classical compositions by m'self: Check 'em out

Jack White covered his like accoustic thingy that he plays Seven Nation Army with paper to keep it preserved, due to it's old age.

Standard Gibson SG
Schecter Hellraiser C-1 FR (My Baby)
