The logical thing to do would be to install one using side LED dots on a neck. Octave dots = in tune. Either side sharp or flat. It all sounds so easy.

Believe it or not, that was destined for my second GB bass - however, there was a number of things to consider about it which ultimately, led to the idea being canned. Was going to be strobe/sharp or flat setup as you describe.
First up, there's another switch on the bass - another thing to go wrong... and obviously, the switch would mute the main output so if the switch fudged, there goes your bass until you can get it fixed.
Second, you have to code in what you want your tuning to be... most likely B E A D G C... but when there's a drop D on a 4 string bass, how would you cleanly switch between the E and D as what you want to tune to?
Third, the interface is not so so great... if doesn't tell you the note that you are tuning... so the risk of tuning on the wrong string when in a high pressure quick tune situation is greatly increased.
We figured it would be cool to have - just like the G spot on the GBs are... but they are never really meant to replace a stage tuner... and the cost of implementing it... well, you may just go out and buy a separate tuner.
