Providence VFB-1 Vitalizer FB - Active Impedance Converter + Booster



FINAL BOOSTER is now renewed as VITALIZER™ FB!

The Providence VITALIZER™ FB is a successor of the FINAL BOOSTER to represent its true performance and function.

This is the same product as FINAL BOOSTER FBT-1.


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. 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.

The signal goes through the VITALIZER™ FB's circuit even when the pedal is turned off to deliver more vivid sound to the following units.


The FINAL BOOSTER is a full-range booster that emphasizes the sound quality.

It allows to boost the signal that were converted to low impedance on Vitalizer™ circuit up to 20db.

It is designed to minimize the tonal change when you boost the signal a lot through our original switching way as the signal always goes through the booster circuit while footswitch only functions for boost volume's on/off.

Best Uses

Vitalizer™ is ideal to use where you would like to minimize the signal degradation. There are many ways to use it such as the first place after the guitar, before wah or volume pedal that are more likely to degrade the signal, and before the amp or your system. Since FINAL BOOSTER is less likely to affect tone, you can also connect it after other pedal to boost just the volume, or you can also control the gain by connecting it before overdrive/distortion pedal.

*Please be advised the sound may get distorted if you boost too much when you connect Final Booster before Wah or other pedals.

Multi-function LED

In addition to indicating the pedal's on/off status, the VFB-1 LED provides effective visual battery power monitoring. When the battery voltage drops below 7 volts the LED will become dimmer and begin to go out. The effect will still operate at this voltage, but to ensure optimum performance the battery should be replaced as soon as possible.
