Featuring 12AX7 preamp tubes, 6V6 power tubes, and a 12-inch Randall speaker, it combines 20 watts of amplification with switchable Tube Boost and flexible tone controls.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for guitarists who need tube amplification in a self-contained combo, the RD20-112 accommodates home practice, recording sessions, rehearsals, and live performances. Its Clean channel provides adjustable gain for clear rhythm passages and responsive breakup, while the Overdrive channel delivers saturated distortion for rock and metal. A dedicated Tube Boost function introduces additional overdrive to either channel, allowing players to increase gain without switching amplifiers. Separate channel adjustments and a global Master Volume help balance distortion and listening levels. Shared Bass, Middle, Treble, and Presence controls provide further tonal flexibility for different guitars, pickups, and playing styles.\u003c\/p\u003e\n\n\u003cp\u003eThe amplifier houses a 12-inch Randall RD1250-8 speaker behind a heavy-duty steel grille, eliminating the need for a separate speaker cabinet. Its speaker-emulated balanced XLR output supports direct connections to recording interfaces and live sound mixers, while a Ground Lift switch helps address unwanted ground-loop noise. A Class A discrete instrument-level effects loop accommodates compatible guitar pedals and external processors. Three speaker output jacks provide additional cabinet connection options, subject to Randall's specified impedance requirements. The included RF2T2C two-button footswitch allows remote channel selection and Tube Boost activation, making the amplifier practical for both studio and stage applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20W All-Tube Amplification:\u003c\/strong\u003e Combines 12AX7 preamp
