The Vitalizer™ is one of the buffers that converts high impedance signal that are more likely to degrade the sound quality by picking up noise or losing higher frequency sound while going through the wiring and electric circuits to low impedance signal that are less likely to be affected by those problems. The wah and volume pedal tend to degrade the signal and color the tone when high impedance signal is received. The Vitalizer is more effective to be used where the player would like to minimize the tonal change. By sending low impedance signal from the Vitalizer WV to the wah or volume pedal, the player is able to control the vivid signal with minimized degradation on pedals. There are many ways to use this pedal effectively such as at the last position before the amp or first position after the guitar. In a small chassis. Thanks ot its small size, it can be placed in a small space on the pedalboard and helps prevent degrade the signal.
