[Guardian]

Hi, ppl, i have a question for you all!
Does anyone of you use these kinds of pedals? http://www.bosscorp.co.jp/products/en/FV-500L/

If you do, what do you use them for, exactly?

Mmm... It reminded me a video I saw a long time ago... the guy use this kind of pedal (don't think it's te same model...) but you can see what he does with it ...
