Interesting -- never heard of these at all. Will have to do some research.
Xavier, sorry about the zap -- yes, it's not fun at all. Someday I'd love to come to Mexico and see all your gear, projects, and most of all, have a listen (and meet your family as well.) Unfortunately, I don't travel well anymore so it's not likely to happen.
Stay safe,
Jim
