PRS HDRX 20 20-Watt Guitar Amp Head
PRS · amplifier
The PRS HDRX 20 is a 20-watt version of PRS's HDRX amplifier line, a hand-wired, high-gain tube head series designed for players who want the brand's signature saturated, aggressive tone at a lower stage volume than the full-power HDRX models. Built around traditional tube circuitry rather than digital modeling, it targets modern rock and metal players who need touch-sensitive high-gain tone without the volume levels a larger head demands, suited to smaller venues, studio recording, or home practice where a full-size high-wattage head would be impractical. As with PRS's other amp offerings, it emphasizes hand-wired construction and premium components consistent with the brand's guitar-building standards.
