Those ABM headless tuner/bridges can be
somewhat painful to use. I have them on my latest bass, and had them on a Status last year - I can say I'm not especially thrilled with them. Awkward to string, and with flats (or tapes) the risk of damaging the wraps at the head clamp on string changes. The Status I only ever used with double-ball-end strings, and it was only a medium scale by virtue of its "Bend-well". (The strings were actually regulation long-scale "Steinberger" strings). That said, they friggin' stay in tune FOREVER. Which is very nice! I also have a Duke, which escapes the string clamp issues by virtue of its normal machine heads. Never a dead spot on ANY of these basses (and I have had several other headless over the years...). That said, I am a headless devotee now, my current 'main squeeze' headless is very ergonomic and only weighs 4.40 pounds! And I'm looking forward to adding a headless Basslab next year (if all goes well...)
