it actually could be some weird volume pedal that goes really quickly when you play a note so all notes a "violined"
It's a backing track? Sure sounds like one to me, especially since they stop at places and the violins continue to play...

Otherwise, if you really want it to sound like that, you can get a synthesizer pickup put on your guitar and it will do that.

maybe you're not saying the right things? an amp likes to know you care.
