PRS HDRX 100 Guitar Amplifier Head Item Description
This is the PRS HDRX 100 amplifier, an incredible piece of equipment that captures the flexibility, clarity, power and brilliance of 1960s British guitar amps. A continuation of PRS’s popular HXDA amplifiers, PRS HDRX amps feature a refined control layout and a newly-documented “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 100 is driven by four EL34EH power tubes, the best pre-amp tubes available, and a custom-designed Straight Edge output transformer. The power supply and filament design make the HDRX 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 PRS HDRX 100 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.
