</div>i would imagine that as you know the output for the pickup for each<br>
string, you can use it do do 'noise'-cancellation on the outputs for<br>
the other strings. the same principle as noise-cancellation headphones<br>
use<br>
<br>
sorry, i haven't explained that very well, but can't think of better<br>
words - ask if you want it explaining more<br>
