Problems with black fretless outdoors

[Munjibunga]

If the ebanol expands more than the neck wood with increasing temperature by even a tiny amount, it will effectively create a thermocouple and the neck will develop a back-bow until the temperature drops.

I have an acoustic guitar that lived most of it's life in the air conditioning. When I moved it to it's permanent home w/o AC, it took two weeks to equalize. Apparently , the different pieces of wood equalized at their own rate. In between the guitar was unplayable, but once it settled in, it played fine. Try taking your bass out in the humidity in the AM, let it sit all day, and see if the playability changes during this time. That way you know that if you have an outdoor gig, you should take it outside first thing, to let it adjust. If it's a direct sunlight issue though, I'm at a loss. Good Luck

Always let you bass acclimate for about an hour before show time. Check neck relief about 15 minutes before just in case it moves. Adjust as necessary.

I put together my 5 string fretless 20 years ago. To maintain the action and response I like, I have to do seasonal at the least, adjustments of the truss rod. With the extremes in northern WI weather, I just expect it.

Learn to do your own adjustments. I press the low string down at each end of the fingerboard, and adjust for just the slightest clearance of the string from the fingerboard in the center...as close to dead flat without being dead flat. I carry the right Allen wrench in my case and check the truss rod often.

The fingerboard was fed up with being called a fretboard and decided you needed to be taught a lesson.
