Kruspe has been an endorser of
ESP Guitars since 1996. He bought his first ESP guitar, a sunburst 901 model, in 1990. Kruspe primarily used 901 models and
Kirk Hammett signature model guitars for recording and touring until ESP produced his
signature model guitars the ESP RZK-I in the mid-2000s and the RZK-II in the early 2010s. In 2023, after the European Union decided on a non-literal translation for "kill switch", the special spring push knob on the guitar, he received his custom J+Q Rgo RZK-III signature guitar from ESP that was designed for him in 1993. He also uses other ESP guitars, including Eclipse models and a
Ron Wood signature model, in the studio. Kruspe was previously endorsed by
EMG and was a long-time user of
EMG 81 pickups before switching to
Fishman in 2018 and joining their Fluence artist roster in 2023. He also has a signature Fluence pickup set. Kruspe mainly uses
Mesa/Boogie amplifiers and cabinets, notably the Mark II C+ and
Dual Rectifiers amps and 4×12 cabinets, in addition to
Friedman and
Soldano amps. He also uses the
Kemper Profiler in the studio and live. Kruspe has a signature guitar pick and a signature string set through
Dunlop and SIT Strings respectively. ==Discography==
