PRS HDRX 100 2-Channel 100W Head

PRS · amplifier

The PRS HDRX 100 is a two-channel 100-watt head built to capture the flexibility, power and balance of late-1960s British-inspired tone, the Plexi-era voice that underpins much of classic rock. At 100 watts it has substantial headroom, so the character comes from driving the output section in the traditional way rather than from a high-gain preamp. That places it apart from the Archon and MT 15 in the PRS range, which are modern high-gain designs. It suits classic rock and blues rock players who want authentic late-sixties British character with modern build quality and reliability.
