Change line-thickness of arpeggio brackets

[sir.teddy.the.first]

Hi all,

is it possible to change the line-thickness of the arpeggio-brackets or do I
have to recreate this bracket manually if I want to change anything?

 

%%%%%%%%%%%%%%%%%%%%

\version "2.19.83"

 

\relative c' {

  \arpeggioBracket

  <c e g c>4\arpeggio d e f

}

%%%%%%%%%%%%%%%%%%%%

 

The Arpeggio-Object does not seem to have a thickness setting .

 

Thanks in advance
