The PRS HDRX 50 guitar amp head captures the flexibility and balance of late-'60s British-inspired tone in a powerful 50-watt amplifier. A continuation of PRS's popular HXDA amplifiers, HX amps feature a refined control layout and an "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 50 is driven by a pair of EL34EH power tubes and a custom-designed Straight Edge output transformer. The HDRX 50 has the documented 100-watt power supply, which makes it sound much closer to the 100-watt amplifier than a normal 50-watt amp. The PRS HDRX 50 features a 3-band TMB tone stack, 3-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 50 is also designed with internally bridged channels with individual volume controls. This eliminates the need for a jumper cable and allows players to more easily dial in their distortion level and tone by blending the lead and bass channels' individual volume controls, bringing more modern convenience to the amp.
