Seiji

Gibson SG Standard Red (purchased in 1994) and Gibson SG Standard White with Poison Ivy Sign (purchased in 1997)

On the Guitar Wolf blog post (https://ameblo.jp/guitarwolf-seiji/entry-12655800669.html) it says:

"Hey, you guys, don't lean on me like that! Why should I, who is the highest class in this world, bear all your weight? Look at this iron reinforcement, it looks strong, doesn't it? This was because that idiot Seiji threw me on stage, and this place cracked open.But, at that time, he was the foreman at the scene, so when he worked overtime alone, he sent all the young people home. Later, you'll secretly process iron in a corner of the site and repair me.

I like the ratio though. A bit heavy, but not as heavy as a Les Paul. "

"Well, it's okay, you're just getting it repaired. I'll tell you, I'm just as classy as you. I was the one who did well on Krampus' US tour in 1997. The proof is that. Check this out, I got Poison Ivy's autograph at the end of rehearsals in St. Louis, where the tour is ending in 3 days, but it's really hard after that, Seiji gets so excited and plays me at the triumphant return live in Japan. So, as expected, it cracked.It would have been embarrassing if Seiji was tuning it during the live and the neck broke and I bowed.Even so, that tour was fun. Krampus, of course, but the trip with Danny's band ``Doll Rods'' from the Gories was the best!

From the blog post (https://ameblo.jp/guitarwolf-seiji/entry-12655800669.html) of Seiji:

Danelectro Longhorn (1996 purchase)

"Hmph, I'm sorry for all of you who are covered in scars, but please look at my body covered with stars.Since Seiji likes Linkley, I thought until recently that he would take care of me for the rest of his life. However, he recently started a gauze drummer and a noise unit called "Jet Himiko."In that unit, he carries three guitars, and one of them is me. I'm sure they're using it because I look cool, but it's a big nuisance. If you ever get a scratch on my body, I'll hate you for the rest of my life."

"The original pickup is removed and DIMARZIO/DP222Black D Activa for X is installed."

"The pickup installed is SEYMOUR DUNCAN/SH-8b Invader Black. It's originally a loud sound, but it's because of the American climate, Seiji's sweat and beer. Seiji is always connected directly to the amp, but the sound is so great that Americans are asking me what kind of distortion Seiji is using.”

In the book "Jet Rock 'n' Roll!!" on page 103, Seiji mentions that he used an Orville SG guitar. He acquired it during the 1998 Kaminari Japan tour after his primary guitar broke. Unfortunately, it cracked and broke just three days after he bought it.

In the book Jet Rock 'n' Roll!! on page 103, Seiji states that he used a Danelectro 56-U2 Baritone Reissue. He acquired it during Guitar Wolf's US tour in 1998 after his primary guitar broke, but he felt it sounded "too shrill and piercing," leading him to stop using it. 

From the blog post (https://ameblo.jp/guitarwolf-seiji/entry-12655800669.html). This was a signature model SG made for Seiji by Epiphone in 2005. The black and blue stripes design are inspired by his Kawasaki Z Series motorcycle with the same color scheme. Seiji quickly had the black pick guard replaced with a blue one, and later took the neck pickup out and had the bridge pickup replaced with a Seymour Duncan Invader black pickup. It is currently kept in a warehouse in Memphis for when Guitar Wolf tours the USA.

In the book Jet Rock 'n' Roll!! on page 103, Seiji states that he used a LTD ULTRA-200 JP. He had the pickguard spray painted red and used it during their American tours in 90's, but found it difficult to use to the audio socket's flimsy construction, so he stopped using it. 

From the blog post (https://ameblo.jp/guitarwolf-seiji/entry-12655800669.html) of Seiji: This guitar was gifted to Seiji in 2002 during the UFO Romantics tour in Mito. He's only ever used this guitar in the studio using it for roughly half of "LOVEROCK".

In a post by Guitar Wolf on Instagram, Seiji is pictured with his Epiphone SG Special, which had suffered a broken headstock during Guitar Wolf's 2022 European Tour. The guitar was signed and put up for sale at only €500! It seems like he had the bridge pickup removed and covered with black tape.

In the book Jet Rock 'n' Roll!! on page 102, Seiji mentions that he uses an Epiphone SG G-310. He has used multiple Epiphone SG G-310 guitars over the years, with one of the earliest being seen during Guitar Wolf's US tour around 1999. Seiji customized this guitar by painting the pickguard gold and adding a sticker of his idol, Bruce Lee, below the tailpiece.

In this Facebook post taken at the Grand Royale in Oklahoma City on June 2, 2024, Seiji can be seen using one of his most common amp heads he's used, a Marshall JCM800 2203. This might be an older model due to fact that it's input jacks are horizontal.

In a photo taken at the Crocodile Cafe in Seattle, WA on February 25, 2003, Seiji is shown using an Antique White Epiphone SG-70 with a red-painted pickguard and a red-painted-over Gibson logo on the headstock.

In a photo captured by Leonie Moreland during the Guitar Wolf concert at Double Whammy in Auckland, New Zealand on March 16, 2025, Seiji is visibly using a Marshall JCM900 4100, as documented by Red Raven News.

In a Facebook post from January 31, 2026, taken at Club 251 in Tokyo, Seiji is seen playing an ebony Epiphone SG Special VE guitar, which he purchased in New Zealand in 2023 during Guitar Wolf's NZ/Australian tour. He got the pickguard colored red, which has since worn off, with some paint even scratched off near the pickups!

In this Facebook post taken at the Grand Royale in Oklahoma City on June 2, 2024, Seiji can be seen using one of his most common amp cabinets he's used, a Marshall 1960A 4x12'' Cabinet .

In a Facebook post from January 5, 2025, taken at Shinjuku Loft, Seiji's Marshall JCM2000 Dual Super Lead head amplifier is clearly visible in the background.

In a photo taken at a performance in Naha, Japan, on January 25, 2014, Seiji's use of the Marshall 1960B 4x12'' cabinet is clearly visible.

In this photo taken at the Euclid Tavern in Cleveland OH on June 18, 1998, Seiji can be using a Roland JC-40 Jazz Chorus amp. He used this amp on a couple of Guitar Wolf's US tours during the 90's.

In a photo captured at the Cluny in Newcastle, England, on June 5, 2012, Seiji is clearly seen playing an ebony Epiphone SG G-400. This image is credited to chrismoody_ on Flickr, as part of the "Guitar Wolf" photo set.
