Hi folks!

Has anyone here tried this successfully? I am carrying my guitar to a technician tomorrow, because after installing baritone strings action is too high even with the bridge brought down immensely. The manual is kinda ambiguous saying: graphite is in truss rod, it's so rigid that adjustment is not required. Yet, it gives instructions for adjustment. I read stories that new Steinberger basses had problems with a truss rod not functioning... haven't found any experiences with the guitars. So - anyone got info on this?
