USED Martin / OOO-28SQ [11]

The 000-28 "SQ" special specification model, born in the early 1990s amid a growing vintage trend.
This is a 1991 model.
The most distinctive feature of this instrument is the SQ neck, which also inspired the model name.
Instead of the adjustable truss rod found on current models, it employs a square rod structure faithful to vintage specifications, offering high neck rigidity and a strong, focused sound.

The body features the classic 28 style wood combination: Sitka spruce top with Indian rosewood sides and back.
The 24.9-inch short scale and the excellent responsiveness unique to the 000 size provide a well-balanced response from fingerstyle to strumming.
Non-scalloped bracing delivers tight bass, while rosewood's rich overtones combine for a clear, well-defined sound.

As a vintage-inspired model from the 90s, it's now relatively rare on the market, making it a recommended choice for those seeking a specification distinct from the standard 000-28.
The neck has been repaired for a break, and the finish has been refinished. The work appears relatively meticulous, likely done by a professional workshop.
The pickguard has been replaced with tortoiseshell.
There is some damage to the binding and finish near the neck joint.
Additionally, some scratches and dents are visible, indicating moderate signs of use.
The neck shows no significant abnormalities and is in good playing condition.
Condition Grade: B+: Some scratches present, but no issues for normal use.
