This can be a powerful effect if performed at the right moment. I would not use this as a
'showcase' effect---it is just something you do at an unexpected moment or on an offbeat. I gave it
four stars because the effect does have some limitations---but these can be ameliorated by effective
handling, which Garrett covers in detail very well on the DVD. You get two effects and a
DVD---along with some bar-scene performances included on the video. Overall, I am happy with the
purchase!
