Whether you play music for just a gig in restaurants or clubs or perhaps you play it to large crowds of people during concerts, don’t you think it’s not only cool but also helpful to see your musical instrument or even just parts of it when the lights are dim?
In the absence of light, having a glow in the dark string on one’s bass, I would say is cool and at the same time helpful. But then again, if you are reading from the perspective of someone who knows every part of your beloved bass guitar even with your eyes closed, then you can scrap helpful but you sure can keep the word cool 🙂
It is cool. Just think of the effect it will have not only on you but on your audience watching you play your instrument 🙂
