This might belong in the setup and repair forum but I thought it might be just as, or even more, applicable here. I am spending more time exploring higher up--say about the second position up to an occasional foray into the hallowed thumb area. The problem is that the higher I go, the deader things sound. I am not certain if the problem is my relatively stiff Engelhardt S-9 or my relatively stiff technique. The bass actually as a fairly defined tone in the lower positions, but the tone and resonance faded out quickly as I climb. I think part of the trouble may be in my left hand because I don't finger the notes as cleanly as in the lower regions. Ideas, thoughts, suggestions?
