Made principally from paper IIRC. I had an ebanol board on an Ibanez GWB fretless, perfectly sound, although it can mark up and go a little grey. A fretted instrument might be different.
Someone’s being greedy. It’s the problem with the multiple choice option, you can’t limit it. The photo comp (November voting currently open #shamelessplug ) tends to have the reverse, with folk not using all of their allocation.
My favourite JE track by miles. I was shocked when I heard it in isolation, but it’s not meant to be heard that way, it’s part of the track, albeit, apart from the vocals, the main part of the track.
