It's just an idea, but when you slap on a fretted, obviously that sound and tone comes from the strings hitting the fretts. The fretts doing most of the work are the top two. So, I was just think to get this slap out of your frettless, if you place say 2 fretts at the very high end of the neck, you would be able get that fretted slap when slapping and also that frettless sound when fingering. What do people think ? Or is this a stupid idea ??!!!!
