    It's no mean feat squeezing a Marshall Super Lead into a 20 Watt package but thats exactly what Paul Reed Smith  and Doug Sewell did with this HDRX 20, distilling the essence of Jimi Hendrix’s Woodstock Marshall into a club friendly package. Along with its bigger 100 and 50 watt brothers, this HDRX 20 uses lessons learnt from analyzing the amp, currently resident at Museum of Pop Culture in Seattle, to attempt to get a step closer to his elusive tone. 

    Utilizing a pair of 5881 valves, both bass and treble channels are internally jumped so that you can achieve just the right balance. 

    This immaculate package is just ripe for ripping things up. Both head and cab are featherweight making it perfect for loading in and out. Do you need any more excuses to put your hand in your pocket?

    A word from the manufacturer…

    “Authentic Hendrix” Touring Circuit

    The PRS HDRX 20 captures the flexibility, power, and balance of late 60’s British-inspired tone in a lower wattage package. The PRS HDRX 20 features a newly-documented “Authentic Hendrix” Touring Circuit. This circuit 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.

    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.
