Stephen Carpenter: Deftones Guitarist, Signature ESP Guitars, and Health Update

Stephen Carpenter is the co-founder and lead guitarist of the alternative metal band Deftones, known for his detuned, dissonant, heavy riffing style. He plays the Focus Keyword instrument — extended-range ESP signature guitars, moving from six strings up to seven, eight, and even nine strings over his career. In 2025 and 2026, Carpenter became newly known for a Type 2 diabetes diagnosis and related weight loss, alongside continued questions about why he no longer tours internationally. This article covers his biography, his ESP/LTD signature guitars, his health journey, and his current status with Deftones.

Carpenter matters to guitar culture because he helped pioneer extended-range playing in a mainstream rock context, long before “djent” became a genre label. His work directly shaped how Deftones sound on albums from Adrenaline (1995) through Private Music (2025). Fans search his name alongside “8 string,” “9 string,” “ESP,” and “weight loss” because his gear and his health have both become major talking points recently.

This piece separates confirmed facts from reported claims, especially around his net worth (estimates vary widely) and his reasons for skipping international tours. It also clarifies a common mix-up: a different person named “Stephen Carpenter” appears in legal and corporate directories, unrelated to the guitarist. Read on for his biography, guitars, health update, and FAQs.

Career Timeline

Stephen Carpenter Guitars: 6-String to 9-String

Carpenter began his career playing a traditional six-string guitar with Deftones. Influenced by bands like Fear Factory and Meshuggah, he moved to a seven-string in the late 1990s, and after White Pony, subsequent albums were written on seven-strings.

Diamond Eyes (2010) and Koi No Yokan (2012) were written using an eight-string guitar, and 2020’s Ohms features a song written on a nine-string. He has said live that he no longer owns any six-string guitars and now plays exclusively 7, 8, and 9-string instruments.

Signature guitar lineup:

• ESP STEF B-7 (7-string signature)
• ESP STEF B-8 (8-string signature, built at ESP’s Tokyo Custom Shop)
• ESP STEF-T7B (7-string baritone)
• ESP SCT-607 / SC-608 Baritone (LTD-line signature models)
• ESP LTD SC-200QM (semi-hollowbody)
• Custom Shop 9-string, first used on Ohms

Pickups

Carpenter’s newer signature guitars use Fishman Fluence Stephen Carpenter 3-Voice Signature pickups in active electronics, a shift from the EMG 808X/707 pickups he used on earlier models. He uses Dunlop Heavy Core .011–.069 strings on his 8-strings, and .011–.050 with an added .11 on his 7-strings.

2026 update: ESP expanded its Signature Series for NAMM 2026 with new kitted-out models for Carpenter, alongside artists like Mick Thomson and George Lynch, confirming his signature line remains active.

Health Update: Type 2 Diabetes and Weight Loss

In 2025, Carpenter revealed he had been diagnosed with Type 2 diabetes the prior year. His health problems limited his involvement in recording Private Music, leading Chino Moreno to perform most of the album’s guitar parts.

Speaking to Premier Guitar in a rig-rundown interview filmed in Milwaukee, Carpenter said he had likely been diabetic longer than he knew, deteriorating because of it, and only accepted and began treating the condition that year. He described pain so severe in his right arm that he could barely move it.

Evidence Check: Weight Loss

• Confirmed: Carpenter has publicly discussed visible weight loss and Type 2 diabetes management.
• Reported: Online forum speculation ties the weight loss to GLP-1 medications such as Ozempic, which are prescribed for Type 2 diabetes and can cause weight loss as a side effect.
• What remains unclear: Carpenter himself has not publicly confirmed using any specific medication; this connection is inference from fans and commentators, not a direct statement from him.

Why Doesn’t Stephen Carpenter Tour Internationally?

Carpenter has not toured internationally with Deftones since 2022, with Lance Jackman and Shaun Lopez filling in on overseas dates. At the time, he stated he had decided to remain playing domestically “for now,” citing world events and not being ready to leave the country.

He has since attributed the decision to flight-related anxiety that intensified during the pandemic, telling Rock Feed that he could either keep feeling anxious every time he traveled or simply stop doing it. He has also said the decision to stop touring internationally predates the pandemic, tied to longstanding anxiety around flying.

Multiple reported factors:

• Anxiety around international flying
• Concerns tied to his public vaccine skepticism
• His long-running Type 2 diabetes management
• A Facebook post from bandmate Richie Londres also linked the reluctance to the 2015 Bataclan attack in Paris, where Deftones were scheduled to perform the following night

Chino Moreno has said even he isn’t fully certain why Carpenter avoids international shows, though the band supports his choice to prioritize his health.

Stephen Carpenter Net Worth

Reported net worth figures for Carpenter vary considerably across sources, and several low-quality sites confuse him with unrelated people (including a similarly-named Slipknot musician). One recognized celebrity finance outlet lists his net worth at approximately $5 million as of a June 2026 update, built primarily from decades of Deftones album sales, songwriting, and touring income.

No reliable public salary figure has been confirmed for his earnings from Deftones specifically. Given how widely third-party estimates diverge, none of these figures should be treated as official.

Is There a Connection to a Lawyer or “FirstService”?

Searches sometimes pair “Stephen Carpenter” with “lawyer” or “FirstService LinkedIn.” Research turned up several unrelated professionals named Stephen Carpenter — including attorneys in Oregon, Washington, and elsewhere — with no public evidence connecting any of them to the Deftones guitarist or to FirstService Corporation. This appears to be a name-matching mix-up rather than a documented fact about the musician, and this article does not present it as one.
