I have one of these.
Here's the truth:
They are all screechy with no real low tone until you put in about 3000 hours practicing.


Ask any parent who has a kid playing. BTW, the screechy sound is caused by the bow, not the fiddle. Try more rosin and a better rosin.

Electric and acoustic are way different birds. I would stick with an acoustic at first. Electrics dont make any sound, and they sound absolutely awful without a Pod or some effect unit. Direct recording of one won't work without effects.
As for an acoustic, If I had a small budget I would head for a pawn shop. Look for something that looks well made and pretty, seriously. Look for cracks or seams open, and avoid that. You could try getting a bow rehair, or a better bow. The bow is what produces the sound. "Screechy" means that the bow is not being controlled and is slipping on the string. A combination of even pressure, control, good hair and good rosin will fix that.
Try "Dominant" strings, they are good. Anything below them (Names like "Super-Sensitive, D'Addario, Red Label") are made for fiddling and are going to sound lousy. Strings are pretty expensive, find a mail order to save money.
Violin= screechy. It's not like other instruments, the bow is the problem.
