Awww, Biddlin, a little Goo-gone and it's back to normal.
I've seen these student aids before, from lap steel lessons with a fingerboard sticker, to a Japanese Shamisen book that had a strip of paper with the notation symbols to affix to the side of the neck.
come on man... that just isn't right. I can see putting a marker on the 12th fret but man not a big fan of marking the others. Oh and why exactly did you need to mark the first fret???
Still... everyone should feel free to customize their guitar any way they see fit so if it helps you... that's what matters most. Can you feel the stickers when you move up and down the neck? That would probably be my main concern. Well that and my jamming buddies would for sure give me a hard time if I did that to my guitar. Of course... then they would probably comment on how maybe it will help my sloppy playing so its all good!
just thought maybe I should just mention that we are all just having a little fun with this and no real dis-respect for the OP. Like worm said... we are assuming you wanted to have a little fun with it based on the original post. BTW, love watching that guy on military show! That would be one of my dream jobs getting to shoot all those cool firearms for a paycheck!!!
I use it to help me play guitar better. Sometimes I get lost where I am on the neck, or if I'm reading tabs having the fret markers help a lot. I also don't feel it when I'm going up and down the neck. I imagine at some point it will wear off and fall off and I guess that's when the training wheels comes off.
