I came up with this idea in my sleep. I had a bass that I was playing in a concert. In the dream the bass had a neck 2 parts to the neck, and I was able to the slide the top half of the neck out and put in another half neck. You're probably wondering why I'm rambling. Because in the dream it was to make the bass fretless. I know you could technically just buy a fretless bass. But what if you aren't rich. Like me. And just want to play fretless sometimes. I don't have money to be buying more than one bass every year or 2. So the idea boils down to this. I just want to know do you think it's a good idea and will it work? The neck has a hollow slide part. Think of it has a whole neck with only a small half an inch slot to slide this part neck in and out. It slides all the way up to the nut, which since has the fretless and fretted points will be higher and lower, can in turn be screwed to be made a little higher to accommodate the slight difference in height of the necks. I wanted to call it the transformer neck. If it can even be done that is. Do you guys think this is possible? I became very excited about this idea. Because I feel it is a good one if it can be pulled off. I know alot of people would be thinking the same way as me. I don't want to shovel a hell of a lot of money out for a fretless. And if it was to be a quick change of the neck and not a painful long one. It could be possible to change the neck on stage for a song, and then change back in between a small break.
