Although all our band pretty much hate oasis, we thought that doing "****ing in the bushes" would be a really nice little intro.

There's a bit in it which is like on a rock organ. Atm, I just play it with normal distortion.
I do however have a zoom G2 and thought that I must be able to somehow emulate the sound to be reasonably close to it it using the G2.

I've been tweaking but can't seem to get it, I thought a bit of vibrato might be good, or chorus. Has anyone got any ideas of how I could get a reasonably close sound? (even if you only know it for different pedals i.e. what effects should I use and what setting etc.)
