The idea of the eBow is appealing to me. My main instrument these days is a fretless acoustic bass guitar (my web site is under construction but there is a picture of it up) that actually bows well on the inside two strings but won't on the E and G due to lack of body clearance. I saw a guy at NAMM last year using an eBow quite effectively but the several times I've tried one I can't get it to drive the strings. I don't expect to have instant technique with the thing but I have doubts about it being able to drive flatwounds on an acoustic bass guitar. Anyone ever hear of mods to beef up the eBow's output (or what ever makes it work) or have any other experience with them?
