EKO's philosophy of offering fantastic value for money is perfectly embodied in the DUO, combining aesthetics and attention to detail. The open-pore satin finish allows you to clearly feel the wood, vibrating under your touch. The fingerboard and bridge are made of South American Roupana, and like other series, the A and Acw shapes feature a 46mm nut width and a 630mm scale length. The wooden binding is rounded for maximum comfort. The amplification system is the Fishman Flex Plus T with a built-in tuner display.
