You need a guitar, bass, drums, strings and a beat. I'm afraid you have to use the keyboard. If not, consider simplifying the arrangement, omitting some unattainable melodies, two guitars (a tonic, a rhythm, 1 bass, 1 drum. ) Pull out some melodies of the acoustic electric guitar. It's done with a simple edit. The drums of this song are brilliant, and the drummer's skills must pass.
