Hi Leonard,

What sort of tone problems are you experiencing? Scratchiness, thin  
sound, warbling, pitch instability, screeching? All are possible and  
mean different things. Poor tone quality can mean many things, so  
anything more specific you could provide would help in diagnosing the  
problem.

My initial thought is that you should look at three factors: cotton,  
shimming, and rosin. The high end is more sensitive to these factors  
and if you've got problems with them you'd expect to hear them up  
there. In general the high end of the range is by far the most  
sensitive to problems and anything over the high C (on a C/G  
instrument) will be particularly sensitive. Without more description  
of the precise sound it's hard to say what might be a factor.

My hunch, however, is you should look at your use of rosin. One easy  
experiment that might give you an answer: if the sound is too tenuous  
and lacks a rich response, try adding more rosin. Many players,  
particularly those relatively new to the instrument, don't use enough  
rosin. If you're using too little rosin cranking faster would, to a  
limited extent, make up for the lack of rosin and improve (but not  
entirely) fix the tone. The reason is that if you have too little  
rosin you aren't able to efficiently transfer the energy of the wheel  
into the strings. Cranking faster puts more energy into the system.  
While it doesn't improve the efficiency, it does ensure that more  
energy ends up in the strings (through brute force), leading to an  
improvement in tone. The top end will be more sensitive here because  
higher frequencies correspond to higher energy states, meaning that  
the inefficiency becomes more pronounced at higher pitches. You want  
to have a transference of energy that is as efficient as it can be  
without overloading the strings. The beautiful thing about rosin is  
that it encourages slip-stick friction that works with the natural  
capacities of the strings, so you really can't use too much rosin as  
long as you apply it correctly.

(Alden, I still intend to create a video on applying rosin, and I've  
scripted it out and listed all of the shots needed to do it right, but  
I've realized it's a *lot* of work to do it right. I want a video no  
more than ten minutes in length, but that will take about four to five  
hours of raw footage plus editing to get right. That's why it's not  
surfaced thus far at all.)

Hope that helps,

Arle
