This artwork represents the three major types of guitars – classical, acoustic and electric. They are represented by stylised ukuleles (which don’t necessarily come in these formats). The name Three Phase refers to not only the style of guitar, but also the stage at which the player may be at, often switching between these types of guitars to suit the style of music they are playing. And finally, the name also refers to the heavy duty power supply which can fill stadiums with the sounds of amplified guitars.
