This effects processor has many nice features and is really portable — it’s convenient to use, for example, during practice sessions. However, I needed a pitch shifter or octaver, and unfortunately, the one included here sounds unusable. Most of the cabinet models also didn’t meet my expectations in terms of sound quality (I was looking for a budget compact unit for an electric violin). Maybe they work better for guitar players. On the positive side, I really liked how the delays and reverbs sound. It turned out that one of my cheaper pedals actually provides a better overall sound quality. (FOR MY PURPOSES* E-violin)
