The Randall RT503H tube amp head from the RT series is an extremely flexible, all-tube amplifier head offering a range of tones from clean Country and Jazz to full Metal and Shred. Each amp features black chrome steel grill and control panel, spring reverb, and an effects loop.
In addition, the Randall tube amp head features a power tube bias section allowing you to bias the power tubes yourself, an easy and money-saving operation detailed in the instructions. This user-friendly bias section on the back allows the player to replace, bias & match the tubes themselves with just an inexpensive volt meter available at any electronics or home improvement store. The Randall RT503H amplifier head from the RT series uses 12AX7 preamp tubes and 6L6 power tubes that can be swapped out with EL34s for a more British vibe.
The Randall RT503H amp head features three discrete channels. Channel 1 is a Classic Clean, which allows you to go from sparkling tone to highly overdriven force. Channel 2 is a Classic Overdrive, bringing your tone from mild grit to full saturation. Channel 3 is a Modern Overdrive, which brings out full high-gain sound. The EQ controls include bass, middle, treble, and a bright switch on the clean channel, so you can pinpoint your ideal individual amplified guitar voice. The master controls on the Randall RT503H amp head include volume and reverb, for that full sound and depth. Series EFX loop, switch for rack or pedal compatibility, and an included 3-mode footswitch round out the package.
