I've bought an electronic Cello (mainly because some of my pupils are interested and I would like to be able to help) which has the Problem that the a and c strings work very well, but the d and g strings are very noticably less responsive and simply much less loud. Ofcourse, it could be the electronics (Piezo). However my acoustic Cello has had such a Problem, though not as bad, before a Change of Bridge, so I was wondering if a Bridge can be cut is such a way that it brings out the middle two strings more, or somewhat mutes the outer two.
Or, if anyone has any idea at all what might help, I'm very happy About any Suggestion!
