The PRS HDRX 100 captures the flexibility, power, and balance of late 60’s
British-inspired tone. 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.
Made in PRS Guitars Stevensville, Maryland, USA factory, PRS HDRX 100
amps are an exhaustive recreation of tone, a celebration of history, and a
monument to modern technology. PRS has also designed matching 2x12
and 4x12 cabinets for the HDRX Amp family. Loaded with modified Celestion
G12H-75 Creamback speakers, these cabinets push and punch to complete
the package.
“Designing the PRS HDRX was not an exercise in over-engineering – it’s
a fairly straightforward build with the right parts and circuit. We kept
historic specs where it made sense, and we made substitutions based
on availability, safety, and experience. In the end, I think we have made a
great-sounding amplifier with exceptional build quality and enough power
to blow your pantleg when you play it,” Paul Reed Smith.
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.
