Spiral Electric FX Yellow Spiral Drive


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

Size Matters, and the Yellow Spiral Drive allows you to control your low-end content with it’s 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 -through for leads, or completely unfettered low-end pant-rippling thunder.

The Yellow Spiral Drive also utilizes the Nanolog N2 Molecular Junction mixed with silicon or LED diodes to tailor the gain to your particular taste.  Works great with either guitar or bass, rhythm or lead, clean or dirty.

Each Yellow Spiral Drive has a unique oxide finish, but the same killer tone. 

The Yellow Spiral Drive has a wide variety of uses: “Always on” tone sweetener, clean boost, dirty boost, low-gain distortion, mid-gain distortion, amp input punisher, and “unleashing the fury, everything on 10” lead shred-o-rama. Select changes to the basic circuit also make the Yellow Spiral sound fantastic on bass with none of the low-end loss commonly associated with this circuit. The addition of the Nanolog N2 Quantum Junction, the Girth control, as well as selectable clipping sections adds a useful and modern spin to this classic circuit.
