Frequently Asked Questions

The neck is slightly slimmer and more rounded than some vintage Martins, offering a modern feel while retaining excellent playability.
The finish is a delicate nitrocellulose lacquer; it’s susceptible to scratches and wear with regular use, requiring careful handling.
While purely acoustic, its projection and tonal complexity are excellent for stage; a separate pickup system can always be added professionally if needed.
