To a reasonably competent pub gig level I'd say bass and rhythm guitar, could also probably get away with a short set of saz and ukulele tunes, too. Got around thirty instruments like bouzouki, cifteli, oud and setar but there's no way I'd claim to have any grasp of the skill needed to say I was a player of them. They're simply there for me to dabble with and enjoy and explore the different styles, modes and tones of music from around the globe.
