I recorded this little folk instrumental on a Merlin M4, a 4 string diatonic instrument inspired by the dulcimer, made by the Seagull company in Quebec, Canada. This one is set up in an open D tuning. A great little instrument to noodle on, mine covers the folky tunes like this, as well as old school gospel blues and old timey classics.
