“We just received our O450, O350 and D350’s today. All I can say is wow!!! The best quality I’ve seen in that price point ever and I’ve been around the block a few times. Becoming a Walden dealer was the best choice for us ever!”

~ Crawford Perkins, SoGlo Guitar Gallery, Brunswick, GA – USA

The STANDARD O351E is an affordable Orchestra model acoustic-electric guitar featuring an all Mahogany top, back and side. All Mahogany guitars are powerful, balanced guitars well suited for many styles of playing from blues to fingerstyle. The O body is optimal for smaller players looking for a more intimate experience than the full sized Dreadnought. Less susceptible to climate changes, its laminated Mahogany soundboard is more stable than a solid top. On-board Walden EX-4 electronics with tuner are included on this model.

STANDARD 300 line instruments focus on creating the best balance of sound, stability & price. The combination of a laminate Spruce top, and a Glass-fibre reinforced Mahogany neck provide exceptional stability and resists changes due to humidity. Its laminated Mahogany back & sides and Rosewood fingerboard & bridge contribute to its tonal and visual beauty. A gloss finish protects the STANDARD 300. Includes Walden gig bag.
