I'm curious as to why no one in the U.S. does this commercially. Is the volume too low to pay for the start-up investment? Is the labor/cost too high versus what people are willing to pay? I've got a full LED equipped 55-94. I've got a second 55-94 which I would like with side dots and 12th fret LEDs, but the cost and shipping to England are stopping me. I'm confident if the cost is comparable to SIMS, and we don't have to worry about the international shipping, quite a few bass players would have LEDs installed. I'd like to hear thoughts from luthiers so I'm posting this here instead of Bass general.
