This pedal sounds great and is really easy to use. The effects sound top quality - delays and verbs are beautiful and I like that a couple of distortions/dirt FX are included even though it's an acoustic pedal. Helps for making leads pop out a bit when looping with a separate looper pedal.The acoustic models are subtle and may not represent a sound improvement for your guitar (this is true of other acoustic modeling pedals as well due to the number of factors involved, like model, pickup, amp or PA, etc.), so if this is your primary interest I would urge you to test and compare with other modeling pedals.Being able to place this pedal's integrated looper at the beginning of the chain to audition effects is so practical and useful btw, and the included tuner is highly visible and accurate. Included software is intuitive and adds a ton of value.The casing is plastic and I wish it was metal but it's very heavy duty and looks like it will last. Just wish it had a tad more weight to it. Other than that, I can't think of any negatives.Highly recommended if you're primarily interested in great quality effects for your acoustic rig. A no brainer at this price.
