The White Spiral Boost by Spiral Electric FX is a dirty boost pedal designed to provide increased harmonic content with a touch of grit. It can be used as an "Always On" boost or as a last-in-chain boost to enhance the amp's dirty channel. The pedal features a Girth Control, which is a rotary cap network that can either restrict or increase bass, and an Alpha/Omega toggle to change the position of the Girth Control in the circuit. The Grit Control utilizes JFET amplification and Silicon clipping to produce a natural-sounding low-gain grit/grind that complements dirty amp channels. Additionally, the pedal operates at 18v internally and is equipped with a hand-brushed aluminum top, powder-coated black bottom, and a matching warm white LED.
