Schaller machine heads on a DB

[slobluesine]

anyone experienced slipping with Schaller P bass tuners on EUB's? are they really up to the job?

If it helps, my Bassix EUB has a set of p-bass style schallers, and they've held up fine for about 7 years now. Mine are mounted on the tailpiece, as it's headless. One thing though - it's irritating to have to trim the strings to fit, as I can't swap them around between the EUB and my double bass, but that probably applies to many EUBs.

i'm blaming the slip in pitch on the tuners because i cant find another reason for it (slips a semitone or so overnight on ALL strings) is there anything else that would cause that?

strings are not new

Doesn't sound to me like the heads at all - they're not about to all fail simultaneously. That would be on a par with a moderate lottery win! Something, possibly something important woodwise, may be giving way. Check structure carefully! Sounds like it might get pricey...Or might be the strings themselves?
