Tc Electronic Rush Booster

A "clean" booster designed for the stage and modern pedalboard

The Rush Booster belongs to the large family of clean boosts: pedals designed to add level without adding artificial "grit." It's a simple and highly effective tool often placed at the end of the chain to gain presence, or upfront to drive an overdrive, distortion, or even the input stage of an amp harder. At TC Electronic, the Rush Booster clearly focuses on the essentials: a discreet analog circuit, a large volume reserve, and immediate ease of use.

For which guitarists (and situations)?

The Rush Booster is perfect if you're looking for a "plug and play" pedal: one single control, no menus, no unnecessary compromises. It suits both beginner guitarists who want a simple boost for louder passages and experienced musicians who need a reliable and repeatable tool for live use.

In terms of styles, it feels at home everywhere: blues and rock to thicken an amp crunch, pop and funk to cut through the band without touching the EQ, or metal to tighten/drive a saturation section (used before a distortion with moderate boost). In the studio, it's an excellent option to enhance a take without changing the overall tone, especially if your sound is already "shaped" by the amp or a main overdrive pedal.

A minimalist pedal: one knob, maximum headroom

The operation is intentionally straightforward: the Volume potentiometer controls the amount of boost. This approach is ideal when you want a pedal that can be adjusted in seconds on stage: you engage it, turn up the level, and instantly get more projection.

Thanks to the true bypass, the Rush Booster disappears when switched off. Its analog design and transparency goal make it an excellent candidate for a light "always-on" use (a small constant lift), or conversely for a spot solo boost. Regarding power, you can use it with a 9V battery or a 9V DC power supply (standard format), convenient depending on your pedalboard setup.

The sound

The Rush Booster delivers a clear, clean, and dynamic boost. The attack remains precise, the lows don't collapse, and the overall impression is of an amp that "breathes" more: more authority, more definition, without excessive compression. At the end of the chain, it acts as a true level enhancer for solos or featured passages.

Placed before a saturation, the pedal can also serve as an "accelerator": you send a stronger signal into the overdrive/distortion, which increases the sustain feel and density while keeping simple control. The result will mainly depend on what you boost: an already crunchy amp will start to sing faster, while a clean amp will stay clean but more present, perfect for cutting through the mix without touching your EQ.
