The "Comfortably Numb" solo is, for many, the greatest guitar tone ever recorded — vocal, soaring, with sustain that seems to last forever. Here's how David Gilmour built it.
What makes the tone. A Strat into a Big Muff-style fuzz, a warm amp, and delay — that's the trinity. Add compression for sustain, and the rest is Gilmour's phrasing and bends. A smooth, mid-heavy voice, not fizzy.
The analogue recipe. Strat, Big Muff-style fuzz, a clean-ish amp with headroom, a delay set to a long musical repeat, and a compressor for sustain. Bend with feeling — the notes matter more than any knob.
On a Boss GT-100 / GT-1000 / GX-100. A fuzz/Muff block into a clean or edge-of-breakup amp, delay + compressor. The sustain and delay are everything.
On a Kemper. A clean/edge profile, a Muff-style fuzz stomp, delay and compressor in the loop.
Skip the guesswork. The Soulster Tonebook for fans of Pink Floyd → has Gilmour's settings for Boss GT and Kemper.
