I purchased my Tama 3560 February 1976.
At that time the Martin D-45 sold for $3800 - $4000.
I gave $500.00 for the Tama 3560 and wouldn't trade it for a Martin D-45
today.
The Tama is an exact copy of the D-45.
The Tama sounds better and is still in mint condition.
Keep your Tama guitars. Once sold you'll probably never get another one.
Martins are built everyday. The Tama guitar is a rare piece of history.
