I'm looking for a pedal the dose like a swell/violin like sound. Something ebow like, or anything really dynamic or soaring sounding. Any recommendations?
Sounds like you want a boss slow gear type effect. Guyatone do the 'slow volume' pedal - samples at http://guyatone.com/microeffects/sv2.html
With the right touch and adjustments you can get a very arco or bowed sound form multiefx that have a fretless sim. I can get pretty close sounds with both my Zoom 607 or Digitech BP-8.
