SRV used this amp for its ability to stay clean at extremely high volumes. This amp was sent through a 4x12 cabinet. According to a 2003 interview with Richard Mullen (published in December 2022 issue of Guitar World), Mullen initially came across Jackson Browne's Dumble amplifier, and Steel Singer was a collaboration between Howard Dumble and Mullen.

An early Ibanez TS9 Tube Screamer effects pedal was placed at Stevie Ray Vaughans pedalboard.

Stevie Ray Vaughan used a Fender Bassman with matching 4x12 cabinet for some stage work.

SRV used this amp for almost his entire career to get a crisp and overdriven guitar tone, also in the picture of his setup.

In the 1989 live performance of "One Night in Texas," Stevie Ray Vaughan is seen using the Ibanez TS10 Tube Screamer Classic, following his progression from earlier models like the TS808 and TS9.

This diagram from Guitar Geek shows Stevie's gear set up, complete with his GHS Nickel Rocker strings.

Rene Martinez, Stevie's guitar tech says about his strings in this *Music Radar article "...He started with a .013 and ended with a .060. They were big, yes, but that wasn't the only thing; it was the action, the height of the strings. I used to adjust the screws down at the bridge to raise the height, and I would run out of thread - I couldn't make the strings any higher."

Stevie Ray Vaughan's Fender Bassman amplifier is owned by Guitar Center and displayed in Austin, Texas.

This guitar is displayed at a Guitar Center in Austin, Texas. It is displayed with the following notes:

Stevie Ray Vaughan “Lenny” Fender Stratocaster

In 1980, Stevie Ray Vaughan came across a ’65 Strat in a Texas pawnshop. Though the pickups had been ravaged by time, and the guitar had been sloppily refinished, something about the instrument resonated with the struggling artist. Vaughan’s wife Lenora pooled together $50 from seven of Vaughan’s friend to meet the $350 asking price, and presented the guitar to him on his birthday. Vaughan was so moved by the gift that he played the guitar all night and penned a song for his wife, playing it for her when she woke up the next morning. The song and the guitar would both go on to be the lovingly names “Lenny” - Lenora’s nickname.

Used while recording "Texas Flood" for the song "Lenny", hence the name of the song, according to a 2003 interview with Richard Mullen (published in Guitar World, December 2022 issue).

Stevie Ray Vaughan used the Marshall 1959SL Plexi amplifier while performing live, as seen in the photo from Firebellyamps.

Stevie Ray started off playing thicker strings in the beginning of his famous career, but later on in his final years he switched to a 11-58 gauge GHS string set.

In the photo, Stevie Ray Vaughan is seen playing a Squier Stratocaster, likely borrowed from a tour crew member.

This custom made figured maple Hamiltone SRV guitar was also used by Stevie Ray Vaughan for stage work.

One of three ever made, this is a custom Strat-style guitar made for Vaughan by James Hamilton in Buffalo, NY, and presented to him as a gift from ZZ Top’s Billy Gibbons on April 29,1984.

The MXR Loop Selector played also a part in Stevie Ray Vaughans pedalboard.

According to Guitar World: "Another key effect that Vaughan used to emulate Hendrix tones was an Octavia fuzz pedal that produces octave-up effects. Vaughan initially used Roger Mayer Octavia pedals (housed in distinctive “spaceship” metal boxes), but when Diaz located three New Old Stock Tycobrahe Octavia pedals, Vaughan switched to those.

His guitar tech, Rene Martinez, says that Stevie thought the Tycobrahe pedal produced the best Octavia effect he had ever heard. Vaughan especially liked how the Octavia sounded when used along with a Tube Screamer." March 2013 Issue, page 65.

SRV used this amp much like the Club and Country, for loud clean tones. He sent this amp head into a 4x10 cabinet.

In this interview, Stevie Ray Vaughan's guitar tech says, "We also had two black-face, EV-loaded Super Reverbs. In addition, we used an EV-loaded Fender Vibroverb, and it powered the Fender Vibratone Leslie speaker."

According to Guitar World:

Although Vaughan didn’t use the Roland Dimension D in his live rig, it was a secret weapon in the studio, where he often added it to his guitar tracks during mixing. Vaughan first discovered the Dimension D while mixing his guitar tracks on David Bowie’s Let’s Dance, and he liked how its subtle chorus effect thickened his guitar sound without changing his natural tone significantly like other chorus effects frequently do.

The Dimension D was used on the solos to “Mary Had a Little Lamb” and “Pride and Joy” on Texas Flood and most of the solos on Couldn’t Stand the Weather. During mixing, Vaughan would add the Dimension D effects himself via the effects send/return controls on the mixing console." – March 2013 issue of Guitar World, page 65.

2003 interview with Richard Mullen (Vaughan's audio engineer, published in December 2022 issue of Guitar World) recalls the use of Dimension D:

One effect he used when we mixedTexas Flood was this Roland delay/chorus [Dimension D] that gave a little bit of a growl sound. It was a stereo device that created phasing effects, which you can hear on the solo to “Mary Had a Little Lamb” and the end solo on “Pride and Joy.” Stevie sat at the board and brought that effect in and out as the song progressed. He used the same effect on Couldn’t Stand the Weather, too.

In this photo, Vaughan is pictured with Gibson ES-335.

In this image, Vaughan can be seen preforming live with a Gibson Les Paul Standard. Though there are many pictures of Vaughan playing this guitar, there is no known video footage of him playing it.

"Vaughan’s wah pedal of choice was a Vox V846 from the Sixties that originally belonged to Jimi Hendrix. Jimmie Vaughan, Stevie’s brother, acquired the pedal from Hendrix when Jimmie’s band shared a bill with the Experience in Fort Worth. Vaughan owned several other Vox wah pedals and was allegedly very fond of an early Seventies version with a Japanese TDK inductor.

Vaughan used the Vox wah on his Hendrix covers and 'Telephone Song' on the Vaughan Brothers’ Family Style, and he famously used two wahs at once to record 'Say What.'"

Photos of the V846 in Vaughan's rig can be found here.

Stevie Ray Vaughan used a Fender Bassman with matching 4x12 cabinet for some stage work.

In this picture, Stevie Ray Vaughan is using a custom Stratocaster replica guitar made by Dallas guitar shop owner Charley Wirz, as is mentioned in this article. In the article, it reads, "he toured with a prized but small selection of Fender Stratocasters that included the famed 'Number One,' its sidekick called 'Lenny,' another called 'Butter,' one called 'Red,' and a Frankenstein model called 'Charley.' (The latter wasn't a true Stratocaster; it was assembled from spare parts by Charley Wirz, owner of Charley's Guitar Shop.)"

According to Guitar World: "For his 1985 Japan tour, Vaughan used a pair of Fender Twin Reverb amps (a mid-Sixties 85-watt blackface model and a late-Seventies 100-watt silverface version with master volume) in place of his Dumble Steel String Singer head. The Twins disappeared from his rig after that tour, only to resurface for a brief period in 1987 when they temporarily replaced his Vibroverb combos." From the March 2013 Issue

This original Ibanez TS-808 Tube Screamer was used by the late Stevie Ray Vaughan. According to a 2003 interview with Richard Mullen (Vaughan's audio engineer, the interview was later published in Guitar World, December 2022 issue), it was the only pedal Vaughan used while recording the "Texas Flood" album.

In this video, Stevie Ray Vaughan's "Number One" Stratocaster can be seen. 1984 Guitar World interview with Vaughan reveals the guitar to be a heavily modified 1959 Fender Stratocaster.

Besides absorbing the essence of Jimi's spirit, Stevie also took a technical tip from Hendrix (and players like Otis Rush) by mounting a left-handed bridge assembly on his '59 Strat. "I like it better, it just makes more sense to me, " he says. "You don't have to really hold on to it. It's right there." Other modifications oh his main ax include a drastic fret job. "I don't like Fender frets," he explains. "I just can't grab onto the strings. The frets just aren't big enough for me to be able to get into it at all, so I use Gibson Jumbo Bass frets. If I didn't, I'd wear 'em out in no time."

According to the 2003 interview with Richard Mullen, Vaughan's audio engineer, the guitar was mainly used on "Texas Flood". The interview was published in Guitar World, December 2022 issue.

In the 1980s, Stevie Ray Vaughan endorsed Tokai guitars and played the Tokai TST 50, as discussed on the Tokai Forum.

Stevie Ray used at least two '64 Fender Vibroverbs modified by César Díaz. They were a part of his amplifier rig since the late 70's. The amps had 15" Electro-Voice speakers in them.

Used for a solo at 3:06 in this March 25, 1987 performance of "Cold Shot" at Ocean Center in Daytona Beach, Florida. Despite the low resolution of the video, Electro-Harmonix confirms the vintage Hot Tubes in this July 10, 2012 blog post and this September 2, 2013 Twitter post.

SRV used this amp earlier on in his career. He used it for loud clean sounds, which is the opposite of how most other people used it and most Marshall amps.

Throughout this video, Stevie Ray Vaughan can be seen playing a Guild JF 65-12.
