Description
The PRS HDRX 50 2-Channel 50-Watt Guitar Amp Head is a masterstroke of modern engineering and vintage charm. Inspired by the very amp that Jimi Hendrix reportedly wielded at Woodstock, this amplifier head merges the iconic British non-master-volume sound with contemporary enhancements. With a custom-designed Straight Edge output transformer, it faithfully captures the essence of late '60s tones, offering a dynamic range that swings from clean chimes to gritty overdrive with a simple adjustment of your picking intensity.
Equipped with a unique "Authentic Hendrix" Touring Circuit, the HDRX 50 projects clarity without harshness, allowing you to explore aggressive tones that can be effortlessly mellowed into sweet, smooth harmonics. The internally bridged channels eliminate the need for an external jumper, allowing seamless blending of the bright Lead and the fuller Bass channels through individual volume controls. This design not only simplifies your setup but also enriches your sonic palette.
Modern players will appreciate the refined control layout, featuring a 3-band TMB tone stack, a 3-way bright switch, high-mid gain switch, and presence controls, providing extensive tone-shaping capabilities. With a robust 100-watt power supply, the HDRX 50 resonates with the might of its vintage 100-watt predecessor, yet operates with minimized hum and hiss, thanks to its advanced power supply design. Crafted in PRS's Stevensville, Maryland factory, this amp is a testament to timeless sound and modern convenience.
