A friend of Treloar suggested a collaboration with a well-known guitar and bass guitar builder, Jimmy, of Alleva/Coppola Guitars.

They met and agreed to create a limited edition of five bass guitars. Treloar first worked on some designs, and then they made a prototype.

Once the process was established and the designs agreed on, Jimmy provided five hand-carved and primed bass guitar bodies. Treloar modified the primed surface and worked on the underpainting of all five at once. He then finished each in oil, and the guitar finisher then clear-coated them all.
