Does this with with a bass?

It works with this range. A0 (27.50Hz) - C8 (4186.01Hz): Sine wave

Can this be used for finding out what note my crystal signing bowl is playing?

I take it that a "signing bowl" is used when performing music for the deaf. The tuner should work with such an instrument if it does in fact generate audible tones.

what is the very best violin tuner?

The Korg CA-2 is nice. Mine is a CA-30 and gets a lot of careful use.
