The George Dennis Wah‑Wah Switch Plus, often known by the model code GD40, is a distinctive optical wah pedal that delivers a Hendrix‑style sweep while offering expanded tonal flexibility. This second‑generation version of the GD30 introduces a dual‑frequency switch that shifts between two sweep ranges, making it equally effective for guitar and bass by offering an extra‑wide frequency response. The design employs an LED‑driven optical sensor for quiet, precise operation and built‑in true‑bypass circuitry that automatically bypasses the effect if the battery dies. Controls include Frequency range (selectable high/low bandwidth) and Volume. The unit features a compact, rugged metal build and a mini toggle switch to flip between frequency modes. Its smooth action and silent footswitching make it reliable on stage or in the studio.
