The cool bass guitar used in that song everyone knows about (used in other Undertale songs as well).
Play around with the velocity/volume to get different sounds (four different samples per note). Sustains and Mutes range from G#4 to G#6.
This also has a bigger range than the bass guitar in The DEFINITIVE MEGALOVANIA Soundfont (https://musical-artifacts.com/artifacts/822).
