The RC-50 is the biggest waste of money I have ever made the mistake of investing in. It's cumbersome to say the least in that it's LOADED with useless features. The guide is the most inept feature of all. If you can't keep time with your foot you have no business looping. I always wanted, and had even wrote and suggested the product 10 years ago, a multiple master stereo version of the good old (noisy as hell) Boomerang which IS the only decent floor looper ever made. What a waste of technology and more directly, efficiency.
