Sky-Stang I

Kurt Cobain played three Fender Mustangs on the In Utero tour, and technician Earnie Bailey named them Sky-Stangs. Sky-Stang I is the Sonic Blue one, serial O 016988, built in 1993 by FujiGen in Japan — it's identifiable in photographs by its white-bobbin Seymour Duncan JB humbucker and a slight V-shaped anomaly in the pickguard. Cobain used it on 53 of the tour's 63 shows, from the October 18, 1993 stage debut at the Arizona State Fair through the final US show at Seattle Center Arena on January 8, 1994, and into the European leg that ended in Munich on March 1, 1994. It was sold at Julien's Auctions in November 2023 for $1,587,500 to Mitsuru Sato, a Japanese buyer who has stated plans to display it publicly.

Why This Guitar Matters

• MTV Live and Loud (December 13, 1993, Seattle Pier 48) is the best-documented single performance — Sky-Stang I is the primary guitar through most of the set, and the professionally filmed footage shows the white-bobbin JB clearly
• Cobain preferred Mustangs over the Jag-Stang he designed himself; the short 24" scale was a deliberate choice, and the In Utero tour is where that preference became fully visible in his stage setup
• The Earnie Bailey modification package — JB humbucker, Gotoh Tune-O-Matic, locked Dynamic Vibrato — is one of the most thoroughly documented custom jobs in grunge-era guitar tech history, reconstructable from Bailey's own interviews and auction catalog notes
• Three identical-looking Sky-Stangs exist; Sky-Stang I's provenance is confirmed by the white bobbins and pickguard shape, which distinguishes it from Sky-Stangs II and III in concert photographs

The Instrument

Specs

The Julien's Auctions catalog (November 2023) is the primary object record for this guitar. Bailey's interviews with Guitar World and similar publications provide modification details that the catalog corroborates.

The Sky-Stang designation was Bailey's naming system, not Fender's. All three Sky-Stangs started as 1993 MG-69 Mustangs from the same custom order. The order itself — ten left-handed Mustangs — came about because the US Custom Shop couldn't build left-handed Mustang necks; Bailey sourced them from FujiGen through luthier Scott Zimmerman instead. The guitars shipped in batches: one Sonic Blue and one Fiesta Red on June 28, 1993; two more Sonic Blues on October 2, 1993; two Fiesta Reds on February 4, 1994; four were never shipped. Sky-Stang I was in the first shipment.

Each Sky-Stang received Bailey's modification package before hitting the stage: body routed for a humbucker, Tune-O-Matic replacing the Mustang's sliding bridge, Dynamic Vibrato locked with the tailpiece reversed and washer-clamped, neck heel shimmed, nut recut. The visual tell that separates Sky-Stang I from II and III is the pickup: white bobbins on the JB (II has black bobbins, III has an orange/red body blotch and a black JB). In well-lit concert photographs, the bobbin color is the fastest way to confirm which guitar Cobain is holding.

Sky-Stang I's Tone and Rig Rundown

Cobain's In Utero live rig ran the guitar through a Boss DS-2 Turbo Distortion, then a Tech 21 SansAmp Classic (acting as an additional distortion/preamp stage), then an Electro-Harmonix Poly Chorus or Echo Flanger and a Small Clone chorus, into a Mesa/Boogie Studio Preamp feeding a Crest 4801 solid-state power amp, and out through Marshall 4×12 cabinets loaded with Vintage 30s. The SansAmp and DS-2 together created a layered distortion — the SansAmp provided compression and a speaker-simulation character that sat underneath the DS-2's harsher upper mids. The Crest power amp is significant: solid-state into Vintage 30s produces a harder, more consistent clipping character than a tube power amp would, which is part of why the In Utero live sound is denser and more abrasive than the Nevermind recordings.

• Attributable to the guitar: The 24" short scale loosens string tension relative to the standard 25.5", which contributes to the slack, easy-bending quality audible in Cobain's rhythm parts. The Seymour Duncan JB is a high-output humbucker — hotter than the original Mustang single-coils, with stronger midrange emphasis. At the gain levels Cobain ran, the pickup's output is somewhat academic (everything is saturated), but the JB's mid-forward character survives even heavily distorted.
• Rig-dependent: The DS-2 + SansAmp combination is the core distortion texture. The Small Clone is audible on chorus-heavy parts — "Come as You Are" being the obvious example, though that was studio. On the live set, the chorus is more subtle. The Vintage 30s add the compressed, slightly nasal quality in the upper mids.
• Player-dependent: Cobain played with a hard pick attack and used the picking hand angle to control feedback and feedback-adjacent sustain. His rhythm parts used downstrokes almost exclusively on the heavier passages. The E♭ tuning is partly about string feel (slightly looser) and partly about key — several In Utero tracks sit better for his vocal range a half step down.

If you could only copy three things from this setup:

1. A Boss DS-2 into a SansAmp Classic — the two-stage distortion is what separates the In Utero live sound from a single-pedal approximation
2. E♭ tuning with .010–.052 strings — the tension and feel are part of the playing style
3. Short-scale guitar — the 24" scale affects both feel and, slightly, tone; a Mustang, Jaguar, or similar short-scale instrument gets you there in a way a Strat doesn't

Provenance: Where It's Been

How the artist got it

Cobain worked with Earnie Bailey to source the guitars through luthier Scott Zimmerman and FujiGen after the US Custom Shop couldn't deliver left-handed Mustang necks. Sky-Stang I arrived in the first shipment on June 28, 1993. Cobain didn't bring it on stage until the Arizona State Fair on October 18, 1993 — nearly four months after delivery — suggesting setup and modification time.

Ownership timeline

Timeline: How It Changed

The guitar toured essentially unchanged after Bailey's initial prep work. The switch trim is the only documented in-tour modification. Bailey's workmanship throughout is notable for its practicality — shimming the neck with hotel stationery is the kind of field solution that gets the instrument working without waiting for parts.

Visual Record

Essential Listening

Sky-Stang I never appeared on a studio recording — it was delivered in late June 1993, months after In Utero was recorded in February 1993 at Pachyderm Studio with producer Steve Albini. Every listening example below is a live recording.

1. "Rape Me" (MTV Live and Loud, December 13, 1993) — The opening riff is the clearest example of the JB's mid-forward character through the DS-2/SansAmp combination. The short-scale Mustang's loose tension is audible in Cobain's bends; standard-scale bends at this gauge and tuning don't feel quite the same, and the pitch instability is part of the character.
2. "Aneurysm" (MTV Live and Loud, December 13, 1993) — A non-album track that appears in most In Utero setlists and benefits from the fuller rhythm density of the live rig vs. the studio recording.
3. "Territorial Pissings" (MTV Live and Loud, December 13, 1993) — Fast, hard-strummed rhythm parts that demonstrate what the DS-2 does to downstroke-heavy playing. The SansAmp compression is audible in how the transients are smoothed relative to the attack.
4. "Heart-Shaped Box" (MTV Live and Loud, December 13, 1993) — Slower and more dynamic than most of the set. The verse clean passages (or near-clean, given how the rig is set) show the JB's single-coil-canceling character — wider and more compressed than the original Mustang pickup would have been.
5. "Frances Farmer Will Have Her Revenge on Seattle" (In Utero Live bootlegs, fall 1993) — Studio version recorded with a different guitar; the live version on Sky-Stang I is heavier in the low-mids. The Tune-O-Matic bridge replacement affects intonation and sustain character relative to a stock Mustang sliding bridge.
6. "Pennyroyal Tea" (MTV Live and Loud, December 13, 1993) — Acoustic on the album; electric live. One of the more transparent windows into the guitar's character at lower gain settings.

Market Context

The comparable basket

"1993 Fender MG-69 Mustang, Made in Japan, left-handed or right-handed, Sonic Blue or comparable finish, player grade — modifications acceptable"

The MG-69 is a standard production model that traded on Reverb for $600–$1,200 in player condition throughout the early 2020s before Cobain-associated Mustangs started pulling auction prices well above market rate. Right-handed examples are more available; left-handed examples carry a premium in any era.

What actually drives price in this segment

• Originality of the finish — Sonic Blue and Fiesta Red are both susceptible to refins; Sonic Blue in particular shifts significantly toward white with age, and some sellers present faded examples as "aged" rather than listing the actual finish history. UV light on the body routes is the standard verification
• Left-handed vs. right-handed — Cobain's guitars were all left-handed; right-handed Mustangs of this era are far more available and trade at lower prices. For a player approximation the handedness doesn't matter; for collector comparability it does
• Japanese vs. US production — MIJ Mustangs from this era (FujiGen, Tokai-era production) are quality instruments; the US reissues are different in feel and construction. The MG-69 is the relevant reference point for this guitar
• Modification state — a stock MG-69 is a different guitar from Bailey's build. If you're building a playing approximation, the Tune-O-Matic and JB modifications are documented and replicable; the locked vibrato is straightforward

Famous-guitar premium vs instrument premium

Sky-Stang I sold for $1,587,500 at Julien's in November 2023 — the eighth most expensive guitar ever sold at auction at the time of sale. It did not eclipse Cobain's Competition Stripe Mustang, which fetched over $4.5 million at Julien's in May 2022. A player-grade 1993 MG-69 Mustang in any finish: $600–$1,200. The provenance premium here is extreme — there's no instrument-level justification for the auction result.

Get Your Own

Off the shelf

Fender's Kurt Cobain Mustang (around $1,400 new) is the closest production equivalent. It's a right-handed instrument configured with a Seymour Duncan JB in the bridge — the same pickup Bailey installed — and a Tune-O-Matic bridge. What it doesn't replicate is the short-scale Mustang feel with the dynamic vibrato locked; the production version uses a different bridge configuration. If you want the locked-bridge, JB-equipped Mustang experience, the Cobain signature is a reasonable starting point.

Vintage sweet spot

A 1990s MIJ Mustang reissue — MG-69 or similar production from that period — in Sonic Blue, player condition. Budget $700–$1,200 for a solid player-grade example; condition and color will move the price meaningfully. Add Bailey's modification package yourself: a Seymour Duncan JB (around $100 used), a Gotoh Tune-O-Matic (around $40), and the locked vibrato setup (reverse the tailpiece and add washers — no additional parts cost).

Watch out for finish inconsistencies on Sonic Blue Mustangs from this era: the pigment was notoriously unstable, and guitars that present as Sonic Blue in indoor light can shift toward white or seafoam depending on age and UV exposure. If the finish history isn't clear, ask for photos in natural light next to a reference. Also check the body routes on any vintage or used Mustang in this price range — routing for a humbucker is a common modification, and a sloppily done route affects value and structural integrity. Standard Mustang bodies have a small pickup rout; a cleanly executed humbucker route is workmanlike; a poorly done one is a red flag.

Build your own

Parts list:

• Body: Short-scale Mustang-style, basswood or alder, Sonic Blue or Fiesta Red finish — period nitro or thin poly both work
• Neck: 24" scale maple neck with rosewood fingerboard — the short scale is what separates this from a Strat approximation
• Pickups: Seymour Duncan JB (SH-4) at the bridge — white bobbins if you want the visual match; black bobbins are functionally identical
• Bridge: Gotoh Tune-O-Matic — the Bailey-specified replacement
• Vibrato: Fender Mustang/Duo-Sonic Dynamic Vibrato, tail reversed and locked with washers — or simply block the vibrato entirely for the same functional result
• Hardware: Chrome tuners; white pickguard (with or without the V-shaped anomaly)
• Setup targets: .010–.052, E♭ tuning, medium-low action for aggressive rhythm playing

Myths and Disputes

• Myth: Sky-Stang I is on In Utero → Reality: In Utero was recorded in February 1993 at Pachyderm Studio. Sky-Stang I was delivered June 28, 1993, and made its stage debut October 18, 1993. The album was tracked with different guitars. Sky-Stang I is an In Utero tour guitar, not an In Utero recording guitar.
• Myth: All three Sky-Stangs are identical → Reality: All three started from the same MG-69 template and received the same Bailey modification package, but each is visually distinguishable. Sky-Stang I: white-bobbin JB, V-shaped pickguard anomaly. Sky-Stang II: black-bobbin JB, yellow mark under bridge pickup. Sky-Stang III: orange/red body blotch, black JB. Identifying which guitar appears in a given photo requires checking these markers — they're consistent enough across the tour to be reliable.
• Disputed: Whether Sky-Stang I or II appears in specific concert photographs → Best read: White bobbins visible = Sky-Stang I; black bobbins = Sky-Stang II or III. For any photo where the pickup detail isn't clearly visible, the attribution is uncertain and should be stated as such. Bailey's inventory notes, referenced in auction documentation, provide the most authoritative assignment of guitars to specific tour dates.
• Myth: Cobain preferred the Jag-Stang he designed → Reality: Per Bailey's account, Cobain's preference by the In Utero period was clearly for Mustangs. The Jag-Stang was a design exercise that didn't fully satisfy him; the Mustangs were his working guitars. He used Sky-Stang I on 53 of 63 shows.

FAQ

What is Sky-Stang I, exactly? A 1993 Fender MG-69 Mustang (Made in Japan, serial O 016988) in Sonic Blue, modified by Earnie Bailey with a Seymour Duncan JB humbucker, Gotoh Tune-O-Matic bridge, and locked Dynamic Vibrato. Kurt Cobain used it as his primary guitar on the 1993–1994 In Utero tour.

Why is it called Sky-Stang I? Earnie Bailey named the three Sonic Blue and Fiesta Red Mustangs "Sky-Stangs" — a compound of "Strat" and "Mustang" with Cobain's signature blue-sky aesthetic. Cobain's own notes refer to the guitar by this name. Sky-Stang I is the specific designation for serial O 016988 (Sonic Blue, white-bobbin JB).

Is Sky-Stang I on any studio recordings? No. In Utero was recorded in February 1993; Sky-Stang I arrived in late June 1993. All documented uses are live performances. The studio guitar for In Utero was different.

What modifications did Earnie Bailey make? Body routed for humbucker; Seymour Duncan JB (SH-4) with white bobbins installed at bridge; original Mustang bridge replaced with Gotoh Tune-O-Matic; Dynamic Vibrato locked (tailpiece reversed and washer-clamped); neck heel shimmed with hotel stationery; nut cut for .010–.052 strings. Jim Vincent trimmed the switch tops during the 1994 European leg.

Where is it now? Sold at Julien's Auctions in Nashville on November 18, 2023 for $1,587,500 to Mitsuru Sato of Japan, who has stated plans to display it publicly. As of the sale, it was no longer in MoPOP's custody.

How much did it sell for? $1,587,500 at Julien's "Played, Worn & Torn" in November 2023 — the eighth most expensive guitar sold at auction at the time. A portion of the proceeds went to the Kicking the Stigma mental health nonprofit. For reference, Cobain's Competition Stripe Mustang sold for over $4.5 million at Julien's in May 2022, which remains the higher of the two Cobain auction results.

How do you tell the three Sky-Stangs apart? Sky-Stang I has white-bobbin Seymour Duncan JB pickup and a slight V-shaped anomaly in the pickguard. Sky-Stang II has black bobbins and a yellow mark under the bridge pickup area. Sky-Stang III has an orange/red blotch on the body and a black JB. In concert photographs, the bobbin color is the fastest visual identifier.

What's the closest guitar I can actually buy? Fender's Kurt Cobain Mustang (around $1,400) is the production answer — it ships with a Seymour Duncan JB and Tune-O-Matic. For a vintage MIJ equivalent, see the vintage Mustang page for current used market pricing on 1990s Japanese Mustangs.
