507 7-String

Nearly two years in the making, the 507 is the best 7 string that we have ever produced. Every detail was considered based on the specific needs and preferences of 7 string players. We reshaped the body, neckjoint, neck and pickup selection all to follow the feedback that we gathered from players.

The 507 features a new fast-comfort neck profile carved into a 5-piece neck. We selected a multi-ply maple and walnut neck for added rigidity, stability and resonance. The 507 is equipped with specially-voiced Rockfield pickups. We expand their tone options with our Great 8 wiring mod, that gives you 8 great tone settings.

The 507 is available with a burled maple top (in Black Burl color) and with a striped ebony top option. Two great looks, both with the same great tone and performance. See all the details on our 507 7-string guitar below.


Great 8 Mod

The Great 8 electronics mod is one of our most demanded mods. With this mod we double the sonic spectrum of our two-humbucker instruments. You still have the full powered tone of each humbucker and the traditional settings to give you neck, bridge or both. With Great 8 we add two push-pull switches to the volume and tone knobs, that when pulled up one coil of the humbucker is disengaged giving you a cleaner single coil tone. You can control each pickup separately, maximizing your options. What can you do with 8 sonic options?
