Upgraded Violin Bass Guitar. The sound of a Violin Bass is unlike any other bass. When used with flatwound strings it produces a distinctive deep and penetrating thud not unlike an upright double bass. This sound can be used to emulate those pop sounds of the 1960s or slightly overdriven in a modern rock band to provide a deep driving bass. It is also commonly used today in studios for recording bass lines for dance music. It has also seen increasing use in reggae bands where a deep driving bass is always wanted. Despite being one of the smallest basses available it easily produces massive bass lines and is remarkably versatile.
