I don't have a zoom (I use a POD XT) but unless you have those single coil pickups he uses you won't get that scratchy picking sound... unless you have a pickup emulator? Try looking at his website, some guitarists like Vinnie Moore show their setups... otherwise go to Line6.com and check out the POD settings for Yngwie, you should get an idea of how to program the same effects to your Zoom
