This is a first-year example, produced in 1977 at the beginning of the unit's four-year production run, in excellent original condition. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003ca href=\"https:\/\/kcvintageguitars.com\/products\/1960-fender-jazzmaster-purple-pre-cbs-slab-board-clay-dots-offset-jaguar-stratocaster-scale\" class=\"group\/tag relative h-[18px] rounded-full inline-flex items-center overflow-hidden -translate-y-px cursor-pointer\" target=\"_blank\"\u003e\u003cspan class=\"relative transition-colors h-full max-w-[180px] overflow-hidden px-1.5 inline-flex items-center font-small rounded-full border-0.5 border-border-300 bg-bg-200 group-hover\/tag:bg-accent-900 group-hover\/tag:border-accent-100\/60\"\u003e\u003cspan class=\"text-nowrap text-text-300 break-all truncate font-normal group-hover\/tag:text-text-200\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/span\u003eThe big-box EHX format of this era — the large enclosure with the characteristic graphics and slider layout — is the visual identity of the most collectible period of Electro-Harmonix production.
