The Tone-Gard is designed to isolate the back of a mandolin from the player's body, producing more volume and enhancing the tone. The original "Sunrise" Tone-Gard fits any standard F or A style mandolin. 

• Laser cut steel with ceramic powder coat
• All surfaces that come in contact with the instrument have rubber and leather pads where needed to protect the instrument’s finish
• Will fit almost any standard A5 or F5 style mandolin - approx. 9-7/8″ across the back (+/- 1/16″)
