This multi function tool simplifies edge profiling, slot cutting, and hole opening so you can produce consistent results faster and with less rework. Key benefits Precision and consistency: Holds guides and templates in place to create repeatable roundovers, binding trims, slots, and holes that match your templates and patterns. Saves time and reduces waste: Faster than hand filing and chiseling for edges and slots, so you finish more parts with fewer errors. Versatile for instrument work: Built for common guitar construction tasks including edge trimming, fret slotting, and cavity or tuner hole opening. Easy to integrate into a workshop workflow: Works with standard router accessories and common woodworking bits so setup is straightforward. Main functions and features Round edge trimming: Accurately trims and profiles and back edges, binding and purfling areas, and radiused contours on acoustic and electric guitar bodies. Slotting capability: Guides for controlled straight slot cutting on fretboards and bodies for truss rod channels, nut areas, and other slot requirements. Hole opening and cavity work: Controlled routing for pickup cavities, control cavities, tuner bushing holes, and sound hole finishing. Adjustable depth control: Allows precise depth setting to match template or design requirements and maintain repeatable cuts across multiple pieces. Compatibility: Designed to work with common handheld routers and standard router bits and templates used by luthiers and cabinetmakers. Durable construction: Built for repeated workshop use and stable operation during finishing and shaping tasks. Compact, bench friendly footprint: Fits on a workbench or fixture table without occupying excessive space. Practical use scenarios Acoustic guitar binding and roundover finishing: Mount the workpiece to a template, set the depth, and trim the binding and edge to a consistent radius across multiple bodies. Fretboard and neck slotting: Use the slotting guide to cut straight, evenly spaced channels for frets or truss rod channels on replacement necks and custom builds. Electric guitar cavity and tuner hole opening: Route pickup and control cavities and cut tuner holes with controlled depth and a clean entry that reduces chipping and cleanup time.
