The Yellow Spiral Drive can do it all: Gain, Grit, Grind, and most important - Girth. 

The Yellow Spiral Drive allows you to control your low-end content with its unique “Tonehenge” Girth control. The Girth control is a capacitor network selector that allows you to go from controlled lows to fit in a mix, cut for leads, or completely unfettered low-end pant-rippling thunder. This Limited Edition Silverburst version features multiple aesthetic and electronic changes from stock, but it still retains its classic voice.
