On the song "Fox on the Run" by sweet, the very intro uses a echoing synth that sounds like a ray gun or something. what gear are they using and for future reference what is the sound called. Instead of me searching youtube for alien ray gun synth. I am playing a show and would like that noise to be during our intro. HELP!! Do I need to get a synth keyboard or is there a way to do this sound from my guitar with some pedals?
