Looking for a good ? acoustic guitar sample

what does good mean ? My nord stage has “Ac Guitar Finger”. It’s a nice sample(s) not a lot of bright transients. Anything similar I could get going on the Zynthian ? I don’t think I want a karlplus strong string algorithm probably a good sample. The mda electric piano is surprisingly good sounding and small any similar acoustic guitar samples or intruments in the open source world I don’t know about ?
