I just invested in a BT7 to go on my MIM Fender Jazz. Between new pickups, control rewiring, new bridge and D-Tuner, it's pretty riced at this point; there's not a lot more I can do to it and still call it the same bass. The new tuner installed without a hitch, but there is a slight problem; if I tune the E-string perfectly, then toggle the lever back and forth, it ends up significantly sharp. After this first toggle, both notes are now sharp. I've tightened the tuning gear and the key adjuster as much as I feel comfortable doing, with no real change in behavior. Now, if I tune flat at first, toggling the lever puts the string in tune at both notes, so that's an acceptable workaround if I can be relatively certain the string will stay in tune (I'm not holding my breath). But, it's still really weird that even when tuning up into the note, downtuning and uptuning results in a higher pitch. If anything, I'd expect the machine not to hold pitch, and to end up flat after retuning. Anyone have insight on this? Do I have things put together too tight, or too loose? Did I get a bad one? Does the tuner just need to break in a little so it will move more freely when toggled?
