Throughout Loudness' tenure, he has mostly used Marshall amps, ranging from Lee Jackson-modified Super Leads in the early-mid '80s, the JMP-1 preamp throughout the 1990s and 2000s, the JCM2000 DSL100, TSL100, and Modefour MF350 in the early-mid 2000s, and the JVM410H in the late 2000s, which is currently his main amp. Starting in the early 1990s, after the release of "Loudness", Takasaki began using the Marshall JMP-1 preamp, which would be the center of his rig ever since, with other amps being along the side.
