FV-30L : is the best for my synthesizer!

The constructive metal material and non-slip grip of the pedal is designed to make this pedal comfortable and last a long time. It's also, equipped with: a) a side jack to connect directly to a tuner, if you wish, b) an expression jack to connect to an amp, synthesizer, or any other kind of equipment designed to alter your instrument's "voice", if you wish, and c) a min-max control knob to set your parameters toe-up to toe-down providing you with a comfortable parameter with which to work within. The movement of the pedal (toe-up to toe-down and vise versa) is smooth, also depending on how you set the min-max control knob. Simply put, the more toe-down you place on the pedal, the stronger your guitar's signal strength through your chain to such receivers as a pedal board. This pedal is very user-friendly and intuitive to use once you become accustomed to setting the min-max control knob to your desire. Chances are, if you purchase and make a sincere effort to initially work with this pedal (which is easy and quite effective), you will not be disappointed and so eager to return the pedal back to it's supplier!
