The DigiTech HardWire CM-2 is a tube overdrive pedal that has what you're looking for, whether you need a little gain in front of your clean combo or just some boost into your distorted tube head. The CM-2 pedal's Classic/Modified option switches between classic overdrive circuitry for a smooth overdriven tube sound to a fatter, hot-rodded tone with extra gain without stepping on your signature tone. Low and High tone controls open up endless sonic possibilities.
