What classical stringed instrument (violin, viola,cello, bass) is most like a bass guitar?

I want to learn bass guitar, and I'm trying to find out how easy it will be to convert from my current knowledge of the viola and cello, to the bass guitar note wise.

The Upright bass and Electric bas guitar are both tuned E-A-D-G where the violin, cello etc. are tuned differently. Being that you can read bass clef you'll have that side down. Mainly you'll need to learn to transpose some scales and your right hand (if you are right handed) is going to have a heck of a work out learn to pluck the strings. Lyrically you'll have a good advantage for soloing etc. and a developed ear.
Reply:Because they are all played in the bass cleft, it should be pretty easy to convert. and if you are a violist and/or cellist, the difference in string thickness shouldn't bother you that much. Good luck in learning!
