Whooo.
"dumb question"... was ... dumb... because in the dark vast vacuum of my 74 yr old mind, I was almost certain there was at least this many examples of dots/markers DIY, and I was almost certain I had read about them somewhere as well.
I did a cursory search for dots or something vague in the forum and had a brilliant (but dumb) thought; post the question! Lazy! and glad I did!
I made the comment before that a lot (it seems) of custom ukes had minimal to none f/b markers/dots which I think is for aesthetics.
Hell, I've always lusted after those huge Gibson blocks of pearl or whatever on their jazz (?) guitar fb's.
I remember a comment from a chiropracter whom I really admired for his knowledge and diy skills, this was almost 2 decades ago, he became known for his home made wooden clocks, one day made a Uke; it was more of a curio than a fine instrument, but again he was no musician and couldn't play a lick anyway, who commented that decent musicians guitar players don't and shouldn't need f/b markers... I kind of had to agree because classical guitars don't have them afaik, and I admired him too much to disagree; wasn't worth the argue.
That kind of rhetoric has stuck with me; when I see them on famous custom pieces...watching Corey and Kalei, paying no attention to the fact there are no markers. To them side markers are enough.
Look at my sig... my 2 new ukes have like zero f/b dots markers,
Actually my Ken Franklin has wooden artistic rectangle on 5 and 12... but its darkish wood almost invisible even in daylight.The Kinnard, none, nada. I love them dearly!
I was also a bit lazy when I bought them; rather than signing up for an unknown time of waiting for a custom build... in the past ordering a custom I always labored over the type and dimensions, not to mention the added price spec with my William King tenors.
Not to mention in the dark! My wife is a totalitarian tyrant who cannot abide the least bit of light coming out of my room at night if she's gone to her bedroom... for various reasons (bless her heart). It may be the Drill-Sergeant in her; "LIGHTS OUT!" Goodnight Dad. (we did have the hugest argument about it about 25 yrs ago... I obviously lost)
As far as where I play on the f/b... One of my favorite things about music is discovering the different tonal sounds of the same notes/chordings etc up and down the f/b and deciding how each could best fit into an arrangement; the possibilities seem endless; are endless... like my posts, and the reason my repetoire is almost always unfinished.
I think that covers it... now for the stick-ons to choose.
