Randall RG3003H Guitar Amplifier Head, 300W 3-Channel Solid-State

Randall RG3003H Guitar Amplifier Head - 300W 3-Channel FET Solid-State

The Randall RG3003H Guitar Amplifier Head is a 300-watt, three-channel solid-state amplifier designed for electric guitarists who need powerful clean tones and high-gain distortion. Built around field-effect transistor (FET) circuitry, it delivers 300 watts at 4 ohms and features independent channel controls, an adjustable noise gate, and a footswitchable effects loop.

Designed for hard rock, metal, and other high-gain guitar applications, the RG3003H provides three distinct channels for different playing styles. Channel 1 handles clean tones with a dedicated Bright switch, while Channels 2 and 3 offer progressively stronger overdrive and distortion. Each channel includes individual Gain and Volume controls, allowing musicians to balance their preferred sounds without constantly adjusting the master output. A shared four-band equalization section provides additional tonal flexibility, while Bass Boost and Mid Scoop switches help shape low-frequency response and midrange character. Whether used as a 300-watt guitar amplifier for live performances or a three-channel solid-state head for rehearsals, the RG3003H offers extensive control over gain, equalization, and overall volume.

The amplifier also includes practical features for recording, practicing, and professional sound reinforcement. An integrated noise gate with adjustable Threshold control helps reduce unwanted noise during high-gain playing. The switchable serial effects loop accommodates external guitar effects, while the speaker-emulated XLR output connects directly to recording equipment or a mixing console. A stereo media input allows musicians to play alongside external audio sources, and the headphone output supports private practice by muting the speaker outputs. Two parallel speaker connections support compatible cabinets with a minimum combined impedance of 4 ohms. The included RF1503 four-button footswitch provides remote channel selection and effects loop bypass control.

Key Features
