Pedal questions. Ring mods. loopers and feedback.

I did a search and found some useful info. However, I thought I would throw out some questions;

1. debating between the Z. Vex Ringtone and the MoogerFooger. I really like the Ringtone's ability to be on or complete way (in terms of sounds). I don't know much about the Moog. Which do y'all think is more user friendly and has the most available sounds in the box.

I'm not concerned about a 'one song use' pedal type thing. I am very, very curious as to how much bizarre-ness I can get from either or both.

2. Anybody see the videos on YouTube with the Z. Vex and the Moog and the rhythmical feedback loops that was going on? What or how do I pull that off with either ring modulator?


3. Can't decide between the DL-4, the Akai or the Digitech Jamman for a looper. What is best for on the spot looping/overdubbing. I know the Digi has the save feature, but is it the better on the spot pedal.

What do y'all think?

Thanks ahead of time and apologies for rehashing old stuff.
