I just got an Ebow at the suggestion of a friend... long story short, an electronic bow to simulate a real (horsehair) bow. It's a fantastic thing! I have a few real Glasser bows and the Ebow is more dynamic. It has different phase directions, changes drastically depending on where you hold it in relation to the p/u's, how far away and I like to let it slightly rub to get some growl in the hum.
It's great for creating swells and harmonics.
I threw up some recorded samples. Nothing extravagant, these are just short, repetitive linear melodies I was making up on the spot and are just the direct guitar signal recorded into a looper. I used the Ebow differently for each. It's pretty subtle except for the last one....
