The HDRX 20 Amp Head captures the Hendrix-inspired tube head magic of PRS’ HDRX line in a lower-wattage head that’s ready for action! Back in 2018, Paul Reed Smith and PRS Amp Designer Doug Sewell got their hands on Jimi Hendrix's Woodstock-era amplifier — a late-'60s British model. After meticulously studying the original amp's circuitry, PRS retooled and refined it, giving rise to the HDRX series. This amplifier head features 5881 power tubes that break up well at lower volumes, three 12AX7 preamp tubes, and an all-new master volume knob that makes nailing saturated tones a breeze, even at low volumes. You'll appreciate the HDRX 20’s streamlined control layout, versatile channel blending, and powerful EQ features like 3-band EQ, presence, and gain controls. If you’re chasing an authentic British-style amp with a dash of American ingenuity, the PRS HDRX 20 was tailor-made for you!
