The Hiwatt DR504 is a classic 50-watt, all-valve guitar amplifier head from the British brand Hiwatt, originally designed in the late 1960s by Dave Reeves.

It’s known for its huge clean headroom, punchy low end, and “hi-fi” clarity, delivering a powerful, articulate tone that stays clean at volumes where many amps start to distort. The DR504 is a high-headroom, crystal-clean powerhouse that defined part of the classic British rock sound.
