nocables

Good afternoon from Jersey, all. Lifelong five string bass player, first time going wireless. I love my recently purchased G75. My question is, has anyone had a problem with the silent tuner feature not working, or working erratically? Sometimes, the unit will engage when attempting to tune, sometimes not. Still, on other occasions, the unit does not respond to open string strikes at all, particularly the "B" string. Any help from would be greatly appreciated. Thanks.
