From my experience, lowering the tuning will result in less tension on the neck which probably results in the need to re-adjust your truss rod, string height, and intonation. When I played bass, I used five of them, all tuned and setup differently. I own a Slammi (similar to Pitch Fork operation) and I think it will drop down to an octave below the A string on bass. I don’t own a bass anymore, but it works flawlessly for guitar, and is great for raising or lowering the pitch of all the strings at once on the fly, so scale patterns remain constant.
