    Review by Benon 30/05/2016
    The review by daniel of the sy300 was right on. Daniel is the premier equipment rigger with this awesome review. I watched every video on the sy300. I called better music and they knew how powerful the sy300 was. This blew my mind since other dealers had no idea. I off loaded near 850 on this phenomenial dragon of a pedal.... Save loads with hand built studio synths with a fraction of the money. Get the sy300 from better music. Get it now. Maybe even two. Rainey day? The price was super good. Even with us dollars conversion to aud. Guitar players . your new pedal for 2016
