A guibass is a cross between a guitar and a bass. A guibass is made by taking an old shit-ass classical guitar and prying out the tuners with a screwdriver and replacing them with bass tuners. 4 bass strings are then added. This instrument makes virtually no noise.
My friend Mike made a guibass out of his old classical guitar. I slapped him and called him an asshole.
