Washburn EA12 Mini Jumbo in Black. Washburn designed the Festival series to address the needs of the performing musician and it has succeeded for over 25 years. The Festival series was the standard acoustic/electric guitar seen on MTV’s “Unplugged” series and has since become one of the best selling and most copied guitars on the market. A large body teamed up with quality electronics, hardware, and fine woods allows the pristine, crystaline highs to blend perfectly with a full, well rounded low end.
