Even though his signature amplifier is based on the 100 watt "1959" model, Malmsteen is most noted for preferring 50 watt "1987" model metal-faced Marshall amplifiers manufactured between 1972 and 1973. His speaker cabinets are always loaded with Celestion G12T-75 speakers. Another big part of his sound is his overdrive pedal, which he uses to push the front-end of the Marshalls. Most recently he is using a Fender Yngwie Malmsteen Overdrive, which is largely based on a vintage DOD Overdrive/Preamp 250 pedal which he used for many years. DOD made a (now discontinued) signature version of the DOD-250 for Malmsteen called the YJM-308 (named after a combination of his initials and the model number of one of his favorite Ferrari's). He has been known to use his overdrive pedals in the loop of a Boss NS-2 Noise Suppressor. For clean tones he employs the use of a Boss CE-5 Chorus Ensemble, and uses a Korg DL8000R in his rack for delays. He often has a Dunlop JH-F1 Hendrix Fuzz Face on the stage-floor, but doesn't use it. Malmsteen claims that he likes seeing the Fuzz Face because it "looks like a land-mine".
