Paul Reed Smith HDRX 20 Watt Head

Paul Reed Smith HDRX 20 Watt Head - Classic British Tone in a Compact Package

The PRS HDRX 20 captures the flexibility, power, and balance of late 60s British-inspired tone in a lower wattage package. Featuring a newly-documented Authentic Hendrix Touring Circuit, this amplifier is heavily inspired by one of Hendrix’s personal amps, purportedly used at Woodstock, which Paul Reed Smith and PRS Amp Designer Doug Sewell were able to study in 2018.

Flexible and Balanced Tone

Designed to push the high-end so it is very clear but not harsh, the PRS HDRX 20 shines without glaring and allows for aggression that can be backed off for smooth, sweet tones. 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.

Enhanced Tone Control

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 and allows players to dial in their distortion level and tone more easily by blending the lead and bass channels' individual volume controls.

Modern Convenience

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 those who do not want to add a volume attenuator to their setup.
