Il explique quelque part qu'il s'était habitué à la largeur des manches 7 cordes, et qu'il peinait à retourner au manches 6 cordes pour les morceaux qui nécessitent un accordage standard.
Il a vu que le guitariste de Limp Bizkit utilisait des 7 cordes accordées ainsi pour jouer les accordages standard et lui a "piqué" l'idée...

Carpenter currently endorses ESP Guitars, Marshall Amplifiers, GuitarRig and EMG pickups. He has been a major endorser of ESP since the mid-1990s with a number of signature six (now discontinued), seven, eight string and baritone models in production.
Carpenter currently uses Dunlop .011-.069 gauge strings. He also uses Dunlop 1 mm Tortex picks which are black with a custom logo. For Koi No Yokan, he utilized a .080 gauge string for the low F# string, since he claims his guitars couldn't handle the .069 gauge, due to the string being de-tuned to drop E.
On tour, Carpenter carries 14 guitars using 7 main guitars, with the rest being used as back ups in different tunings. He used six string guitars in E standard/drop D for Adrenaline, drop D♭/C# for Around The Fur and drop C for White Pony. Carpenter then switched to using seven-string guitars, using G#/A♭ standard for the self-titled album and drop F#/G♭ for Saturday Night Wrist. On the album Diamond Eyes, he used an 8-string in F#/G♭ standard tuning, while on Koi No Yokan Carpenter used Drop E tuning on some songs such as "Poltergeist" and "Gauze" and half-step down tuning (standard F) on songs "Tempest" and "Rosemary" in addition to F#/G♭ standard.
Since transitioning from a 6-string to a seven-string guitar in late 2000, in live performances Carpenter plays the songs originally played on a six-string guitar on a 7-string with the two highest strings tuned to the same note (ex. EADGBEE for Adrenaline), after discovering that Limp Bizkit guitarist Wes Borland did this to some of his seven-string guitars. Carpenter does this because it was harder for him to play a regular 6-string after getting used to the wider neck and longer scale length of his signature 7-strings. The song "Rocket Skates" from Diamond Eyes is played on an 8-string, although Carpenter does not make use of the low F# string. In order to prevent confusion between rigs while touring, he has two identical rigs, one for U.S. tours and the other for foreign countries.
All of Carpenter's guitars feature a middle pickup, but he claims he rarely uses them. Carpenter claims the inspiration for this was from seeing Vivian Campbell with his Buddy Blaze Shredder guitars, which feature a similar pickup scheme.
Carpenter is also a former user of Native Instruments' Guitar Rig, a software program designed to emulate amplifier and effect set ups.
Carpenter's current rig consists of only a Fractal Audio Axe-FX II running straight into the venue's PA system. He also uses an Electro-Harmonix .22 Caliber pedal power amp for powering his monitors.[18]
