This is a great fx unit. TC Electronic sound quality is amongst the best and it lives up to its name. All of the effects are professional grade. The only bad point is that the knobs on the front seem very fragile so I am being gentle with it. Its more a studio piece of gear that robust road gear. They probably reserve the quality build for their more expensive models. Still i don't regret getting it at all. Saves me buying loads of pedals, and... it keeps your signal totally clean without breaking up digitally when the volume pot of the guitar is very low. Very happy with the product. Highly recommended.
