I recently bought a Zon Sonus here on TB and must sell/trade one Zon for my other gear desires. Mahogany body and walnut top The action is incredibly low without buzz, as can be expected from Zon's composite neck. There is a truss rod, though I never needed to adjust it. Satin neck finish makes left hand movement super fast and non-sticky. string spacing: 17mm weight: about 10 pound on my bathroom scale Built in 9/2017, I'm the original owner. All parts are original, the electronics are perfectly noiseless when turning knobs. Comes with all original owner's manual, birth certificate, adjustment tool and Zon hardcase that fits Legacy body shape snugly for best protection with keys to the lock. A few finish chips are shown in the photos, but the bass looks like new from most angles. According to Zon website, a new Legacy Elite of the same specs now costs $7000 after maximal dealer discount, with sometimes years long wait time. Trade interests (+/-cash): Alleva Coppolo or Olinto, 5 string with 18mm or smaller string spacing.
