Hello. I am looking at flat top acoustic guitars to play jazz/jam band music. I am a "quality over quantity" type and only own one guitar, a Mule steel tricone. My Mule covers all the bases for me and then some. I would like to own a wood flat top to play jazz and jam on. I will state I am a Martin fan. The two models I am interested in are the D28 and the 00 28. I think the D28 is a better instrument for jazz with its deeper, bass tone, but I am more familiar with the 00 body shape. Any suggestions or opinions of which you think would be a better jazz acoustic? FWIW the guitar will be acoustic only, no pick ups. Thanks.
