What I mean by the thread title is, do you ever get so into working on the instrument, that your hands start working on doing something, on pure impulse, as if your hands are doing it before your mind can think to do it? Things that you never thought of putting into the original design in your head, to transform the direction that the build is headed, and thus, the final instrument itself? After you finish the instrument, you think of how you imagined it would look when you started, and then you look at the unbelievably different, but very awsome result? I have realized that the bass is in control of how it will become, and the hands are just more or less puppets, mindlessly obeying. I have decided to get a rough idea of my builds, and "let the bass decide" the rest of its outcome. I have many examples of this, but i Would love to hear your thoughts, and see some examples on everyone elses work, before i talk.
