It's very odd using a bow... it's nothing like you first expect it... and it's difficult... depending on the speed of "the stroke", it can sharpen or flatten note (even open strings)...
Drop D tuning sounds cool... it actaully begins to sound like a cello... I'm gonna have to get some web space, and put all my sound clips up, everything from "Slide tapping" to the voilin bow... heheheh
