PRS HDRX 50 Guitar Amplifier Head

All of the clarity and power of a late ’60s British guitar amp built for the modern player with a refined layout and incredible technology, this is the Paul Reed Smith HDRX 50 amplifier. A continuation of PRSs popular HXDA amplifiers, PRS HDRX amps feature a newly-documented Authentic Hendrix Touring Circuit. This circuit is heavily inspired by one of Hendrixs personal amps, purportedly used at Woodstock, which Paul Reed Smith and PRS Amp Designer Doug Sewell were able to study in 2018.

The HDRX 50 is driven by a pair of EL34 power tubers with a custom-designed Straight Edge output transformer. The HDRX 50 mimics the 100 watt power supply while using its own custom 50-watt transformer, which makes it much closer in output and tonal character to the 100 watt amplifier than a normal 50 watt amp. The power supply and filament design also make the HDRX remarkably quiet with little to no amp hum or hiss.

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 (historically used on the outside of the amp) 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.

Please note: This is a vintage stock volume amp. PRS recommends using a volume attenuator with these amplifiers. There are several good choices on the market. PRS recommends the Koch Loadbox LB120 II. Please note, these come in 16 and 8 ohm versions; make sure the resistance matches the cabinet being used!
