The Gearbox Dual is a clever package combining Wampler's Tumnus and Pinnacle circuits, giving you a wide range of overdrive tones.

Frequently Asked Questions
It’s surprisingly effective, especially at higher gain settings, but very aggressive gate settings can introduce a choppy feel – finding the sweet spot is key.
It shines with a clean amp platform, but works well pushing a slightly overdriven amp for added sustain and harmonic complexity.
It offers a true series configuration (Tumnus into Pinnacle) and a parallel blend option, allowing you to combine the characteristics of both circuits.
