Those were exactly my thoughts, and I tried it with violin samples  
from a sample library but I wasn't too impressed with the result. I  
also tried it with Mellotron samples. This gave an interesting  
filter, but didn't sound like a Mellotron at all.
Perhaps for emulation of a violin body a convolution reverb like  
Logic's Space Designer is better? One could tap or knock on a violin  
body, record it and use this as impulse response.
