The PRS HDRX 100 guitar amp head captures the flexibility, power and balance of late-'60s British-inspired tone. A continuation of PRS’s popular HXDA amplifiers, this 100-watt HX amp features 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 100-watt HDRX head shines without glaring and allows for aggression that can be backed off for smooth, sweet tones. The HDRX 100 is driven by four EL34EH power tubes and a custom-designed Straight Edge output transformer. The power supply and filament design make the HX 100 remarkably quiet with little to no amp "hum or hiss."

The PRS HDRX 100 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 HDRX 100 is also designed with internally bridged channels and 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. PRS HDRX 100 amps are an exhaustive recreation of tone, a celebration of history and a monument to modern technology.
