The instrumentation is a mix of standard punk with electronic devices for mechanical tones: A Roland CR-68 drum machine does simultaneous beats alongside a standard drum kit; the Maxi-Korg 800DV synthesizer was used for a unique blipping noise, dubbed by the music press as a "musical stapler". P-Model came to argue with Warner-Pioneer, Sakuma and engineer Makoto Furukawa daily over their instruments: The band picked them because they felt a rough sound was crucial to their theme, the production thought it all sounded bad. Ultimately, P-Model compromised on most aspects of the recording.
