Arp Odyssey MKII - modified w/ Built In Spring Reverb 

That sounds fantastic - it has character. Something about spring reverb makes everything sound like Jon Pertwee-era Dr Who. I have the Korg version and it feels as if there's masses of space inside the housing.

Nice demo of the ARP. Sounds great with the spring reverb. I love the sound of the ARP. I've had to make do with a Korg re-issue but it gets a feature when it's needed for those quirky sounds.

So which unit did you use and where is it mounted? What is driving it and how do you control the amount?

I came here specifically to make fun of the commentor =(
