Query: Not the best of quality, construction or tone

I had problems with this device day 1, I gave it a few weeks, and finally gave up on it, and sold it someone on ebay.Yes, they give you every effect and option under the sun, but for the most part they are low-quality effects and models. You certainly get what you pay for in these all in one multi-effect units.The construction is low-quality as well. The knobs started falling off on me after a week.If you must get a multi-effect pedal you are going to have to spend a lot more money and get a Line6 POD live if you want some quality.
