Guild chose a solid Sitka spruce top and arched flamed maple back to mirror the tone woods that have been used in upright bass construction for centuries, resulting in a clear, tight bass tone that is impressive for its reduced size. The back, sides and neck are finished in a satin antique blonde finish, which adds a rich depth and unique character to the wood’s figure.The Jumbo Junior Bass’s deep voice can be amplified or recorded using its on-board Guild's Fishman-designed Active bass pickup system with built in volume and tone controls. Other standout features include an ebony fingerboard and bridge, bone nut and saddle, mother-of-pearl rosette and Guild peak headstock logo, tortoiseshell pickguard, and nylon-core phosphor bronze strings.
