Hi guys.
I've been onto Martin, discussing whether I should replace the pinch
rollers on my machine. They are original and most definitely showing signs of
wear. He says he can regrind them angling the edges so making better tape
contact. However, I have the feeling that as they have become worn, it has
affected the tuning of one note with another. Surely if you have pinch rollers
that are a slightly different diameter from each other, they will be out of tune
with each other to an extent. So I'm inclined to go for a complete new set.
Anyone else have any opinions on the science of all this?
Cheers.
