Item Weight: 7.8 ounces Product Dimensions: 1.69 x 2.87 x 1.97 inches Item model number: JF-329 Voltage: 9 Maximum Recording Time: 20 mins This Iron Loop like virtually every other Joyo pedal is true bypass which means that all your important tone that you worked hard to create isn’t going to be spoilt by the Iron Loop. It’s a looper that lets you capture it for you to hear time and again in an ultra-high quality 44.1 KHz/16bit sample rate making it a brilliantly clear and unaltered recording. The JOYO JF - 329 Iron Loop is possibly the smallest Looper on the market today and is one of the best loopers available by comparison on price and feature set. You can record, overdub and undo & redo your recordings with the Iron Loop, from a few seconds to 20 mins and the unlimited layering will keep you noodling for hours. Once a loop has been recorded, a ring of LED’s light up and shows you the length of the loop you have recorded. It then counts down to the beginning of your loop again. This makes it extremely easy to see where you are up to in the loop, making it great when you are overdubbing and aren’t 100% sure where you’re up to. This is a great help to everyone from looping pros to people just learning how to use a looper or people who are still mastering their timing.
