Hiwatt DR103 Settings Guide
The Hiwatt DR103 is a 100W EL34 amplifier hand-wired to military-grade standards by Dave Reeves in the late 1960s and early 1970s. It was Pete Townshend's primary amp for The Who, used by David Gilmour on his most celebrated studio and live recordings, and is known for its extraordinary clean headroom — it stays clean at volumes other amps have long since broken up. The DR103's character is fundamentally different from Marshall: crystal-clear, with extreme headroom and a compressed, harmonically rich clean that sustains at volume.
Used by: David Gilmour, Pete Townshend
The best Hiwatt DR103 settings start with: Normal Vol at 7/10, Brilliant Vol at 0/10, Bass at 5/10, Middle at 6/10, Treble at 7/10, Presence at 6/10, Master Vol at 7/10. Adjust from there based on your amp, guitar, and room volume. For Clean / Pink Floyd: Normal Vol 8/10, Brilliant Vol 6/10, Bass 5/10, Middle 6/10, Treble 7/10, Presence 7/10, Master Vol 7/10.

Settings by Genre
Both channels active with Brilliant channel slightly below Normal — the linked-channel approach Gilmour used. The Brilliant channel adds high-frequency sparkle to the Normal channel's warmth. Volume high enough to enter the amp's sweet spot without breaking up. Presence at 7 adds the cutting clarity Gilmour's Comfortably Numb and Shine On tones require.
Full volume on Normal channel — Townshend played his Hiwatts at maximum volume with Fane 4x12 cabs. The DR103 at full volume through a large cab produces extreme SPL with the clean-to-compressed transition Townshend exploited for feedback and sustain. The headroom advantage of the Hiwatt means even at full volume it's cleaner and louder than a Marshall at equivalent settings.
The Hiwatt as a clean pedal platform — its extraordinary headroom keeps it clean well beyond where most amps break up. Gilmour used the DR103 with Big Muff, Electric Mistress, and various overdrives — the clean, high-headroom amp responds transparently to effects without adding its own character to the pedal tone.
Artist Settings
Documented settings used by professional guitarists on this unit.
Gilmour's Hiwatt setup across The Wall and Animals tours used linked Normal+Brilliant channels through Hiwatt cabinets loaded with Fane speakers. The resulting clean tone has extraordinary clarity and sustain even at stage volumes — his OCD-level attention to signal chain meant the Hiwatt's clean character formed the foundation every effect was stacked upon.
Townshend used Hiwatt DR103s at full volume with multiple 4x12 Fane-loaded cabs — the wall of volume and the Hiwatt's headroom allowed him to generate feedback and power-amp saturation at the highest stage volumes. His slightly elevated Bass and Middle settings reflect his rhythm-heavy, chord-driven approach.

Tips & Common Mistakes
- Original hand-wired Hiwatt DR103s are extremely valuable — their military-spec point-to-point wiring and premium components command high prices on the vintage market. Reeves Amplification builds faithful replicas, and Sound City amplifiers (built in the same era by Dave Reeves) are often more affordable alternatives with similar character.
- The Hiwatt's clean headroom is its defining characteristic. This makes it not particularly useful for players who want natural amp overdrive at low volumes — the DR103 wants to be played loud. For home use, a power attenuator between the amp and speaker allows it to reach its designed operating range at manageable volumes.
- The Brilliant channel adds a high-pass filter boost — it emphasises treble frequencies more aggressively than the Normal channel. Running both channels simultaneously (linked) combines the warmth of Normal with the sparkle of Brilliant, producing a more complex frequency response than either channel alone.
