I think there is some Locktite that just tightens up a screw but doesn't lock it up and hopefully you could still tune it. I've never even seen a fingertip let alone play one but there must be some remedy to keep the tuning nuts from moving. Hal and LLoyd played one for years and I don't think they would play a guitar that didn't stay in tune, but again, don't know for sure. I've seen a lot of old Wilburn Bros shows where Hal was playing one and it sounded awesome too.
