First-time poster here. This seems like a great forum . I'm starting a new project building a 7-string bass. Guitar Center here had a Conklin Groove Tools GT-7 for a while which I tried out and liked, but it got sold and now there isn't one at any store in town I can look at. Would it be possible for a 7-string owner to measure their string spacing (center to center) at the nut and bridge to get me in the ballpark? I really dislike spacing less than 18mm at the bridge, but even 18mm would give a total width of about 4.25" (108mm) at the bridge with 7 strings, which seems pretty wide. I'm interested in the compromise width actual 7-strings are being produced at to keep playability. Oh, and also do they have one truss rod or two? This will be my 6th homebuilt bass so I'm not a novice, but all the others were 4-bangers so this is somewhat new territory. Any and all advice appreciated.
