The Rickenbacker 4001 is the distinctive bass guitar associated with Haruko Haruhara in FLCL, the 2000 anime series known for its loud, music-driven action. In that context a guitar is treated as much as a weapon as an instrument, which is why a single hard bash carries both musical and comedic force. Online, short guitar-bash clips like this one circulate as reaction sounds for anime edits and memes, where the familiar twang instantly signals chaos, attitude and over-the-top energy.
