Who John Entwistle was

John Alec Entwistle, born October 9, 1944, in Chiswick, London, was The Who's bassist + co-founding member from 1964 until his death on June 27, 2002. He recorded with the band from My Generation (1965) through Endless Wire (the 2006 record completed posthumously with Pino Palladino on bass), with the canonical catalog spanning Tommy (1969), Live at Leeds (1970), Who's Next (1971), and Quadrophenia (1973).

Documented Rotosound Swing Bass 66 user across the catalog. Played Fender (early), Gibson Thunderbird + EB-3 (mid-1960s), Alembic (mid-1970s), and Status Graphite Buzzard signature (1980s onward).

Style signatures

Three things across The Who catalog you can identify as Entwistle's:

Treble-forward + harmonically rich tone. Rotosound stainless + active electronics + treble-boosted preamps; the bass sits at the front of The Who's mix in a way few major-band rock bassists ever achieved.
Three-finger right-hand technique. Hand speed beyond standard rock bassists; the technique supported The Who's loud + busy arrangements + Pete Townshend's windmill-strum guitar attack.
Lead-bass passages + bass solos. The 'My Generation' bass break (1965) is one of the canonical bass solos in rock, predating most of the lead-bass vocabulary that came later.

Documented strings. Rotosound Swing Bass 66 (.045-.105) as the documented historical production set across The Who catalog.

Bassist hub. Bassists index. Historical British-rock-bass canon parallel: John Paul Jones (Led Zeppelin), Lemmy Kilmister (Motörhead), Paul McCartney (Beatles, contemporary peer), Steve Harris (Iron Maiden, Rotosound continuation).

Frequently asked questions

What strings did John Entwistle play?

Documented Rotosound Swing Bass 66 user across The Who catalog. Entwistle was a foundational Rotosound endorser; his + Lemmy + JPJ + Steve Harris's combined Rotosound use across the British rock + metal canon is part of what built the brand's reputation as the British-rock-bass standard.

The .045-.105 stainless-steel roundwound is the gauge most-often cited in Entwistle's bass-press coverage.

What basses did Entwistle play?

Multiple instruments across his career, organized by era: Fender Precision + Jazz Bass in the early Who era (1964-1968); Gibson Thunderbird + EB-3 mid-Who era; Alembic basses in the mid-1970s through Quadrophenia; Status Graphite Buzzard signature instrument from the 1980s onward (the Buzzard is one of the most-recognized signature basses in rock, designed with Status founder Rob Green). Entwistle's instrument rotation across his career was unusually broad for a major-band bassist.

How did John Entwistle die?

Cardiac arrest, June 27, 2002. Entwistle died of a heart attack induced by cocaine use in his hotel room at the Hard Rock Hotel & Casino in Las Vegas, the night before The Who's 2002 reunion tour was to open at the Joint there. He was 57. The Who continued the tour with bassist Pino Palladino on short notice; the tour and subsequent Who activity have continued without Entwistle since.

What's Entwistle's playing style?

Lead-bass virtuoso vocabulary inside hard-rock arrangements. Three identifiable signatures: (1) Treble-forward + harmonically rich Rotosound stainless tone that pushed the bass to the front of The Who's mix; few bassists in major-band rock history have ever been as audibly prominent. (2) Three-finger right-hand technique that supported The Who's faster catalog (the band's loud + busy arrangements demanded a hand-speed approach beyond standard rock bassists). (3) Lead-bass passages + bass solos integrated into songs (the bass break on 'My Generation,' 1965, is one of the canonical bass solos in rock, predating Cliff Burton's '(Anesthesia)' by 18 years).

What's The Ox + Thunderfingers?

Two of Entwistle's nicknames. The Ox is the older + more-cited nickname, given by The Who bandmates for his ability to drink + outlast the rest of the band on tour. Thunderfingers (sometimes The Quiet One) refers to his right-hand attack speed + the volume + harmonic content of his bass tone. Both nicknames feature in Who-history coverage + on his solo records (his band was variously called The Ox + the John Entwistle Band).

What's Entwistle's solo work?

Six solo records across 1971-1996: Smash Your Head Against the Wall (1971), Whistle Rymes (1972), Rigor Mortis Sets In (1973), Mad Dog (1975), Too Late the Hero (1981), and The Rock (1996). The solo records lean more toward dark-humor songwriter material than the Who's mod + rock-opera + arena-rock direction. Entwistle wrote 'My Wife' (Who's Next, 1971), 'Heaven and Hell,' and many other Who songs across the band's catalog; his songwriting contributions are a large body of work alongside Pete Townshend's primary catalog.
