Used Wishbass 5-string fretless bass. This bass has been heavily modified/upgraded by a previous owner. New nut and floating bridge. New string-thru holes have been drilled to correct spacing from original holes. Lightly engraved fret lines on top of the neck (see pics). And tone selector knob added with custom wood knobs. Comes with black tape-wound strings. Not sure of brand. There is a buzz on the 10th ‘fret’ of the D string, but plays great otherwise.
