My apologies if this is a stupid question...I've only owned headless basses for years, and am only really familiar with doubleball strings. I received a new jazz bass last night via UPS. When I attempted to bring the strings up to pitch (after letting the bass acclimate for about 7 hours) the G was so tight that it felt like either the tuner or the string was going to snap. Literally! When the string got to about Gb, the tuner wouldn't turn any further, and I wasn't going to push it. Any ideas what would cause this? Is it a problem with the tuner, the strings or the set up? Or is it something else entirely? Thanks for indulging my stupidity.
