Bassist wanted

I write psychedelic songs, play guitar and sing, have a rehearsal room, and until now have been playing and recording with a drummer. We're currently finishing our EP, and then it shall be the time to bring them to an audience...and so looking for a suitable amigo/a who plays competent bass, not only playing existing parts but also is capable in extending and improvising upon an existing framework.
