1 DCBirdMan 6 months ago Picked up a 90s Martin D-1.. us made, loads of them around in the $650-$750 range... got mine for $500 and I am amazed at how loud this thing is... beats some D-18s. Doesn't have the depth of a D-28, etc. but for sheer volume produced (13s help!) it's pretty amazing. D-1 may have been the name of their first D size model say in the 1930s, etc but this thing is pretty cool for the price.
