Carlos Lopez built this one for Beyond the Burst and completed it on 24 August 2026. There is nothing else like it: a Conchers doubleneck, a twelve-string baritone over a six-string baritone, in Antigua on an ash body.
Both necks run a 27" scale, which is what makes them baritones rather than long-scale guitars, and both are quartersawn roasted maple with ebony boards, block inlays, white nitro binding and a medium V profile at .850" and .900". Twenty-one Jescar medium jumbo frets over a 12" radius, bone nuts at 1.725", double truss rods, Kluson tuners, natural tint on the necks against the Antigua body.
Each neck carries three of Castedosa's hand-wound TS mini humbuckers, so there are six pickups on the instrument, through custom wiring and a nickel control plate with black knobs. The La Raza fuzz circuit is built into the guitar rather than sitting in front of it, which is the thing people tend to reach for first when they pick up a Conchers Baritone and the reason this design has the following it does. Descendant bridge and trem, twelve-string spacing, aged nickel hardware, Antigua full guard, arm and belly contours.
A baritone twelve is a rare enough instrument on its own. Pairing it with a six-string baritone on one body, with a fuzz circuit inside and six hand-wound pickups, puts this somewhere outside the usual run of custom orders. It is a one-off, and it is the kind of thing that turns up once.
