The Vitalizer™ is a buffer that converts high impedance signals that are likely to degrade sound quality by picking up noise or lose higher frequencies to a low impedance signal that are less likely to be affected by those problems. It is an Active Impedance Converter that Providence has invented to make sure the sound doesn't get too Hi-Fi while respecting the instruments and effect pedals' sound character and signal quality. It delivers natural sound that’s faithful to the instrument by using a special circuit that minimizes the "Active" tone. The Vitalizer B is optimized for bass guitar, down tuned guitar and 7/8 string guitar with its lower frequency range. The Brick Drive BDI-1 features the Vitalizer B circuit on input section which delivers more vivid and clear sound by tightening up the bottom end that tends to get blurred with most other processors and effects. Also, VZ THRU output sends the signal that went through Vitalizer B circuit and converted to low impedance signal. It can be used as parallel out to be connected with other pedals or tuner.
With the carefully picked quality parts and circuit structure specifically designed for bass, it provides more power of expression with low noise. The internal operating voltage is boosted to 21V to achieve more dynamic range.
