Providence Vitalizer BF Active Bass Impedance Converter VZF-1
It is an Active Impedance Converter that Providence has applied original invention to make sure the sound doesn't get too Hi-Fi while respecting guitars and effect pedals' character of sound signals. It delivers natural faithful instrument sound by using a special circuit that minimizes the "Active" sound.
By placing it on the closest spot from guitar/bass in the signal chain, the Vitalizer BF tightens the bottom end that is tend to be blurred with bass, 7/8 string guitar, and drop tuned guitar. Also, it will help prevent degrading the signal or tonal change and reduces the noise from different environmental situations when the pedal is placed in the beginning of the signal chain of the pedalboard. Moreover, it works great even before the amp or where the player feels the signal gets degraded or causes tonal change.
The Vitalizer BF is in a small chassis (60x73/mm) to be placed in a small space on the pedalboard and helps prevent degrade the signal. It needs to be used with external power supply when 9V battery is used. It also runs with AC adapter or power supply.
