i bought a cello bow to play on my guitar, a bc rich warlock special with floyd rose
now i have it tightened for a good tension says my string theory teacher
now even if i have the right tension will it not play without rosin?

also any hints i should know to make a good sound with the boy
this is for fun, maybe only do it one time for a fun way to play an e chord prior to leading into a playing of fur elise
come on does anyone have ideas..or is pretty much me getting rosin all i need n you figure not to comment?
I had to play a guitar with a bow for a theatre production. You'll need rosin. It's no big deal, a little rosin on the strings where you pick won't hurt anything, just give it a wipe with a rag afterwards.

You'll need rosin.

Also guitars are horribly suited for bowing, the necks and bridges are far too flat. Violin type instruments, and viol type instruments have quite rounded neck/bridges to ensure the bow has access to all strings.

Have fun playing E and e.

Just run it through amplitube to get a cello sound. There are a couple clean presets that would work well.
