Sigma DM-1 (1980s, Missing Label)

Title:
Sigma DM-1 Dreadnought Acoustic – 1980s Vintage – Great Player, Label Missing

Description:
Here’s a clean and great-sounding vintage Sigma DM-1 from the 1980s. The original interior label is missing, but the construction, wood set, and build details all match the DM-1 models from this era.

These ’80s Sigmas are known for being well-built, Martin-inspired workhorses with a warm low-end and clear top end — very similar in feel and response to an early D-18 style guitar.

Features:

• Spruce top

• Mahogany back & sides

• Mahogany neck w/ rosewood fingerboard

• Dreadnought body

• Rosewood bridge

• Chrome tuners

The guitar plays comfortably, sounds great, and has the classic Sigma tone that made these models so popular. Perfect as a reliable studio or stage acoustic, or as a vintage daily player you don’t have to baby.
