Standard O450 by Walden Guitars

“It has a more focused intimate tone, rather than the full bodied boominess of a Dreadnought or even a Grand Auditorium. That’s a lotta guitar in a little package! ”

~ Sean Harkness, New York, NY – USA

O450 - Sound Clip: Fingerstyle

The STANDARD O450 is a solid Spruce top Orchestra model acoustic guitar. On this folk sized guitar, a Mahogany body and solid Spruce top with traditional scalloped-X bracing produces a focused, rich and intimate sound expected from a solid top guitar. Woods are seasoned properly and with proper care, this guitar will last for a lifetime.

STANDARD 400. A solid top and a focus on creating the best balance of sound, stability & price is at the heart of the STANDARD 400. A traditional scalloped-X braced soundboard paired with laminated Mahogany back & sides and genuine Rosewood fingerboard & bridge contribute to its tonal and visual beauty. A Glass-fibre reinforced neck provides exceptional neck stability and improves playability. A gloss finish protects the STANDARD 400. Includes Walden gig bag.
