Equipment
The first bass Kouki was seen publicly playing was a painted in a yellow "competition" scheme. After joining Rinava, Kouki heavily modified the Mustang Bass, removing the stock pickups and having the humbucker from a installed in the bridge position and a  stock pickup installed in the neck position. Sometime after recording The Vlok Invasion, Kouki retired this bass from public use due to malfunction, and instead used a variety of high-end basses including a, a one-off , a bass, a , and a black  The Rail Bass.

By Problem? in 1992, Kouki had begun using a heavily modified, nicknamed "The Satanic Beatle". "The Satanic Beatle" had the pickguard removed, was repainted jet black, and had the stock pickups replaced with the stock pickups from a Alembic Persuader. The Persuader pickups were repainted red to "stand out" against the primarily black color scheme of the modified 500/1 bass. Like the Mustang Bass, "The Satanic Beetle" was retired in 1995 due to malfunction, and Kouki switched back to high-end basses for a few years, such as a and a  bass.

By the time of I Wish You Well in 1998, Kouki had begun a relationship with Fender, who released the Kouki Ueda Signature Bass, a higher-end professional variation of the Squier Bronco Bass student model.
