Uprising

The Thermion Uprising is a dual booster designed to recreate the feel and response of a real tube gain stage. Built to enhance punch, presence, and harmonic richness, it can subtly shape your tone, add organic overdrive, or aggressively push your amp into heavier distortion. A three-way gain mode switch (Low, Mid, High) lets you select the level of drive, while the Gain control fine-tunes saturation and response. Independent, footswitchable output levels (Level G and Level R) allow you to switch between two volume settings—ideal for rhythm and lead boosts. For precise tone shaping, Uprising includes dedicated Lo Cut and Hi Boost EQ controls, helping you tighten low end and add clarity or bite. With true bypass and flexible boost options, Uprising delivers dynamic, tube-like gain shaping for stage and studio use.
