SRV's Torn Calluses: Why Stevie Ray Vaughan Super-Glued His Fingers

Stevie Ray Vaughan played some of the heaviest strings in recorded blues history and picked hard enough to wear quarter-inch holes straight through his fingertips. His guitar tech's field fix, confirmed by Vaughan himself, was as unglamorous as it was effective: pack the hole, seal it with super glue, and get back on stage.

Yes. His guitar tech René Martinez packed the torn fingertips of Stevie Ray Vaughan (SRV) with baking powder, sealed the wound with super glue, and filed it smooth so it wouldn't snag the strings. Heavy .013 to .058 strings and a violently hard attack tore his hands apart night after night. Vaughan confirmed it himself in a 1990 interview: 'I like the sound of them, even though it's painful to use them.'

The short version

Stevie Ray Vaughan played some of the heaviest strings in blues guitar, hit them harder than almost anyone on record, and paid for it in torn skin. His fix, and his tech's fix, was not a callus cream or a bandage. It was baking powder packed into the wound, a layer of super glue over the top, and a nail file to smooth the edges so the repair wouldn't catch on the strings mid-song.

This isn't guitar-forum folklore. Vaughan confirmed the pain himself in a 1990 Guitar Player interview, and his longtime guitar tech René Martinez has described the repair method directly, corroborated by the Stevie Ray Vaughan Archive's account of the biography Texas Flood: The Inside Story of Stevie Ray Vaughan by Alan Paul and Andy Aledort.

Strings heavy enough to wear through skin

The damage traces straight back to Vaughan's rig. Per his tech Rene Martinez's documented account of the gauges, his working set ran roughly .013, .015, .019 plain, .028, .038, and .058, tuned a half step down to Eb standard on his primary Stratocaster, nicknamed "Number One." A .013 high E is unusually heavy; most electric players run .009 or .010. Vaughan also picked with enormous force, which is a huge part of his tone and his attack, and heavier strings under a hard attack simply wear a fingertip down faster than a light set under a gentle touch.

Guitar Player's own account puts it plainly, quoting Martinez: "We played so many shows, he started tearing the skin off his fingers and they would bleed." Per the Stevie Ray Vaughan Archive's account of Texas Flood, some of those holes went as deep as a quarter inch, deep enough that simply toughing it out with a callus stopped being an option on a night-after-night touring schedule.

The repair: baking powder, super glue, and a nail file

The technique, as documented by the Stevie Ray Vaughan Archive (citing Texas Flood) was blunt and effective. Martinez, or Vaughan himself, would pack the torn fingertip with baking powder, then apply a layer of super glue over the top of the wound. While it was still tacky, he'd press the finger against his palm, or against another finger, until the glue grabbed and set. Peeling the finger away left a new, sealed layer over the damaged skin. A pass with a nail file knocked down any rough edges so the patched finger wouldn't snag on a wound string mid-solo.

It is a genuine, load-bearing repair, not an urban legend: a working touring musician's answer to a wound that couldn't wait for a day off to heal. It is also not something we're recommending as home first aid. Cyanoacrylate (super glue) does have a real medical history closing wounds, including field use treating soldiers' bleeding wounds during the Vietnam War, but a proper liquid bandage or simply backing off to a lighter string gauge is the safer move for a guitarist dealing with split fingertips today.

In his own words

Vaughan confirmed the pain directly in a Guitar Player interview published in the magazine's February 1990 issue, conducted while he was co-headlining a tour with Jeff Beck. Asked about his string choice, he explained he'd dropped to a lighter gauge temporarily:

"I'm using a lighter setup now because I've got a hole in my finger. Because of the schedule we've had, Rene hasn't had the chance to dress the very edges of my frets, and I just found yesterday that at the points where I play a lot, my calluses were getting ripped off to where it stuck a hole in the finger."

Pressed on whether he'd go back to his usual .013 high E once his hands recovered, his answer doubled as the whole story in one line:

"I like the sound of them, I really do, even though it's painful to use them."

He also mentioned experimenting with even heavier gauges earlier in his career, at one point trying an .018 high E and a .074 low string, before settling into the .013 set that defined his recorded tone. Read the full 1990 interview at Guitar Player.

How other guitarists build calluses, minus the field surgery

Vaughan's case was extreme, but the fix itself is not unique to him. Guitar Tricks' own callus guide lists "a spot of super glue on tender tips as a makeshift callus" as a trick players still reach for, with the same caution Martinez followed: let it set before it touches anything else, or you'll glue your fingers together or damage the fretboard finish.

Ordinary callus-building doesn't need any of that. Skin on the fingertips thickens from repeated string friction over roughly two to three weeks of consistent, short practice sessions, not one marathon session. Keep your nails trimmed, stay off the strings right after washing your hands or swimming, since wet calluses go soft, and never pick or peel a forming callus, since that resets the clock. One tip that circulates in guitar lore and is often credited to Eric Clapton, though never confirmed by him directly, is wiping the fingertips with rubbing alcohol to dry the skin and speed the toughening along.

If your fingers are splitting the way Vaughan's did, the honest fix sits upstream of any home remedy: drop to a lighter gauge, or a coated set that's easier on the skin while your calluses catch up.

What he eventually played instead

Martinez, for his part, kept pushing Vaughan toward something lighter before the damage became permanent. Per the Stevie Ray Vaughan Archive's account, late in Vaughan's life he moved his high E down from .013 toward .011 or .012, and Martinez had GHS build him a custom set in those gauges. After Vaughan's death in a 1990 helicopter crash, GHS released a production version of that lighter set, the Nickel Rockers 1300 Low Tune, as the closest packaged equivalent to what he was actually playing at the end.

Frequently asked questions

Did Stevie Ray Vaughan actually glue the skin back onto his fingers?

Yes. Per the Stevie Ray Vaughan Archive, citing the biography Texas Flood: The Inside Story of Stevie Ray Vaughan by Alan Paul and Andy Aledort, his guitar tech René Martinez developed a field repair for the holes Vaughan wore into his fingertips: pack the wound with baking powder, seal it with a layer of super glue, press the finger against his palm (or another finger) until it set, then peel it away to reveal a new layer over the damage. He'd file down any rough edges with a nail file so they wouldn't catch on the strings.

Why did his fingers get torn up like that in the first place?

A combination of unusually heavy strings and a famously hard attack. Vaughan's tech Rene Martinez has documented his working gauge at roughly .013, .015, .019 plain, .028, .038, and .058, tuned a half step down to Eb standard. That is far heavier than the .009 or .010 sets most electric players use, and Vaughan drove them with enough force that the skin on his fingertips simply gave out, sometimes wearing holes as deep as a quarter inch.

Did Stevie Ray Vaughan ever talk about the pain himself?

Yes, in a Guitar Player interview from the magazine's February 1990 issue, conducted during his co-headlining tour with Jeff Beck. Vaughan said he was using lighter strings temporarily "because I've got a hole in my finger," adding that his calluses had been getting ripped off entirely at the spots where he played the most. Asked if he liked the heavier .013 gauge he'd return to, he said: "I like the sound of them, I really do, even though it's painful to use them."

Who was René Martinez, and what was his role?

Vaughan's longtime guitar technician, and one of the most respected guitar techs in the business, later working with Prince, Carlos Santana, and John Mayer. Beyond the finger repairs, Martinez maintained Vaughan's guitars and famously could swap a broken string or an entire Stratocaster mid-song without a visible break in the performance. He also pushed Vaughan toward lighter strings as his finger damage got worse.

Did Stevie Ray Vaughan ever switch to lighter strings?

Eventually, yes, though reluctantly. Late in his life, after repeated finger injuries, he moved his high E string down from .013 toward .011 or .012. Rene Martinez had GHS build him a custom set in those lighter gauges, and after Vaughan's death in 1990, GHS released a production version of it, the Nickel Rockers 1300 Low Tune (.011-.058), as the closest stock equivalent to what he actually played.

Is packing a wound with baking powder and super glue actually safe?

It is a battlefield fix a working touring guitarist used to finish a show, not a medical recommendation, and we're not presenting it as one. Cyanoacrylate (super glue) has legitimate off-label use in wound closure and was even used as a field treatment for soldiers' wounds in Vietnam, which is likely part of why the trick was already circulating among road crews. If you're dealing with a split fingertip from playing, a proper liquid bandage product or simply a lighter string gauge is a safer first move than reaching for a hardware-store adhesive.

Would lighter or coated strings have prevented this?

Almost certainly, yes, to a degree, though Vaughan's specific tone was built on the mass and tension of a heavy uncoated set. A lighter gauge, or a coated string that reduces friction and finger wear, would have been easier on his hands, at some cost to the low-mid weight and sustain his heavier strings delivered. It's the same tradeoff any hard-picking player weighs today: tone and durability under a heavy attack versus comfort over a long set.

How do guitarists normally build calluses, without the super glue?

Play consistently in short sessions rather than one marathon practice, since calluses need roughly two to three weeks of regular string contact to thicken. Keep your nails trimmed, stay off the strings right after your hands have been in water (wet calluses go soft), and never pick or peel a forming callus, since that resets the process. A lighter string gauge speeds things up for beginners; going straight to what Vaughan played would just tear fresh skin.
