Vortex Sound Research

Hi Guys, I'll be briefly visiting Las Vegas in a couple of weeks.

While I'm there I might be able to visit a music store or two.. I can see on Google Maps there is a Guitar Centre and a place called Sam Ash.. A few others but they seem pretty guitar or string orientated.Can anyone let me know which would be better to see and maybe buy a small synth?

Thanks!

Sorry I should add I have never been in a Guitar Centre or any USA music store..!
