Greta's bass guitar

I have silhouetted a picture of Greta's bass which is her most treasured possession, most expensive item and something she wished she'd started playing sooner.
 I am going to use the curves of the guitar as a starting point for some letterforms.
I could look into other bass guitar curves and shapes but this would stray away from being specific to Greta and there would be no fluent relationship between the letterforms.
