that! IMO, it isn't necessary. <BR><BR>I don't even use the PR function on the

<BLOCKQUOTE class=cite cite="" type="cite">I use a VT also Andrew, and I
find that the upper end of your percent ranges work for me in the tenor
and treble. However, I find that the bicord bass needs closer to 25% and
for whatever reason - I certainly don't understand it - the monocord bass
needs about 40%. I know, I've never heard of anyone using that much
overpull in the low bass, but for whatever reason, if I don't, it'll come
out flat. Strange.<BR><BR>Terry
