Nice one mate. Cool tune. A buddy of mine plays that on his Yamaha Dual Keyboard organ with foot pedals (like wrestling an octopus when I try! lol), and it sounds really haunting...
Frankly speaking, I think chorus doesn't fit the melody but by and large, it's really good. Keep it up! I want to experiment with effects too. I found a review on the best delay pedal and I bet it's gonna be my first effect. Also, I want to buy a tremolo pedal and some else.
