I use mine all the time. I have one from the mid 70s, and one from the 90s. An Ebow, a volume pedal and a delay is a very fun day.
Sweet! I have one from the first year they came out. As you say, Ebow, volume pedal and delay is indeed fun! Great for faux cello, flute, angry whale, happy whale, etc tones.
I also use mine with acoustic guitar. A very unique effect. When used right, it really adds a beautiful atmosphere to the proceedings.
