Huh, that BOSS unit looks pretty cool. I've never run across that before.
What guitar are you playing on it? Just a great tone and sound.
Yeah, it's always great when something comes spontaneously out of your playing that makes you go "hmmm, that's pretty cool - where did that come from!?!?". When that happens to me, it usually start out as a "mistake" where I didn't hit what I intended to...yet it sounds good and I'll continue with it.
