A Warwick Corvette $$ was used as the primary bass by Utsu-P from at least 2015 up until 2017, Now it is used as sub-bass for recording. It was purchased from Grandy in Shibuya. While faced with a choice between this one and a blue bass, Utsu-P ultimately decided on this one due it's price and rare color. Utsu-P says that the lack of fret markers often causes mistakes.

The MUSICMAN StingRay 4 held a prominent role as the bass used in Utsu-P's occasional live performances prior to The Ohayogozaimas' formation.
