The innovations at work in the nylon string Multiacs are available in the steel string models as well. Outwardly the Steel and Nylon models look much the same. Inside, it's a much different story. The top of the Steel string Multiac incorporates a modern variation on the classic X-brace. The slim necks and shallow bodies of these guitars make them exceptionally comfortable to play. The two-chamber body design resists feedback and the custom voiced preamps make for great sound in performance with minimal effort.
