Elicits classic British non-master-volume sound

If you're yearning for the sound of a classic British non-master-volume amplifier, then the HDRX 100 will satisfy your tonal craving. Heavily inspired by the amp Jimi Hendrix played through at the legendary Woodstock music festival, the HDRX 100 includes three JJ ECC803S preamp tubes and four New Sensor EL34EH power tubes, along with a custom-designed Straight Edge output transformer. Like the non-master-volume designs of yore, this tube amp head exhibits incredible dynamics, enabling you to go from clean chime to crunchy grime by altering your picking pressure — try doing that with a modern master-volume amplifier! Push the HDRX 100 to its upper limits, and you'll experience clear, aggressive tones that sing smoothly and sweetly when you back off. Beyond that, this amplifier is quieter than its vintage counterpart, thanks to an updated power supply and filament design — you can crank the HDRX 100 to the max with astonishingly low levels of hum and hiss.

Familiar controls with modern-day flexibility

The PRS HDRX 100's controls mirror those of a historic British non-master-volume amplifier. A 3-band equalizer gives you ample tone shaping; a 3-way bright switch and High Mid Gain switch offer further sonic customization. You also get a Presence control for dialing in your upper harmonics. We have found the HDRX 100's controls to be familiar for guitarists familiar with vintage non-master-volume amps. That said, this modern-day iteration includes increased flexibility and control players couldn't even dream of in 1969.

Convenient internally bridged channels

Just about everyone who played a British non-master-volume amp back in the day jumped its two channels, feeding their instrument's signal through both channels simultaneously for increased gain — that's where the amplifier's magic lies. The HDRX 100 eliminates the need for an external jumper cable by bridging its channels internally. That said, you still get two independent Volume controls for easy blending of its boosted, bright Lead channel and its flatter-sounding Bass channel. Courtesy of its convenient, contemporary design, dialing in the HDRX 100's distortion is a piece of cake.
