The Stinger Boost: A single-transistor boost featuring rare NOS (New Old Stock) transistors, the Stinger Boost delivers classic midrange honk that cuts through any mix. A switchable silicon and germanium circuit lets you dial in everything from glassy bite to warm, vintage saturation. The germanium mode provides a smooth and warm boost, and the silicon circuit delivers a brighter and hard edged push. The pedal’s single Boost knob controls the magic, offering everything from a subtle push to a full-on vintage-style gain boost.
