PRS HDRX20 20 Watt Head

Designed to push the high-end so it is very clear, but not so much that it’s harsh, the PRS HDRX shines without glaring and allows for aggression that can be backed off for smooth, sweet tones. The PRS HDRX 20 is driven by two 5881 power tubes. Chosen for their lower power, smaller size, and organic voice, the 5881 tubes bring thick but articulate tone that drives well and breaks up beautifully in this lower-wattage amp.

The PRS HDRX 20 features a 3-band TMB tone stack, 2-way bright switch, high-mid gain switch, and presence controls. These features mirror the historic amp and give players flexibility and increased control of their tone. The PRS HDRX 20 is also designed with internally bridged channels with individual treble and bass volume controls. This eliminates the need for a jumper cable (historically used on the outside of the amp) and allows players to dial in their distortion level and tone more easily by blending the lead and bass channels’ individual volume controls, bringing more modern convenience to the amp. The addition of a Master Volume control on the HDRX 20, a new feature for HDRX amps, is another modern convenience. Players can use the Master Volume to control the power amp section of the HDRX, making it more user friendly for players who do not want to add a volume attenuator to their setup.
