I am not learned on the topic by the sum of my experience so far is that you need to spend about £200 for a passable violin transducer.

The last time I tried to get a sound out of a £60 violin transducer I finished up with +24Db at 60 Hz and 120 Hz, full low mid-sweep boost, 24 db cut at about 450 Hz plus mahusive reverb and chorus and 24 DB cut of everything above 6k and it was beginning to sound less like a cat being murdered.
