The Providence Vitalizer BF VZF-1 is an Active Impedance Converter for bass: in plain terms, a small active buffer built to clean up the signal from low-tuned and extended-range instruments. Providence says it "tightens up the low frequency that tends to be blurred with bass, 7/8 sting guitar, and down tuned guitar," which is the pedal's whole job in one line1. Premier Guitar's announcement describes the Vitalizer as "one of the buffers that converts high impedance signal," placing it among buffer pedals rather than preamps2.
What it does for your sound
A buffer's task is to convert a high impedance signal so it can drive long cable runs and downstream pedals without losing top end, and that is how Premier Guitar frames the Vitalizer2. What Providence adds is a low-end focus aimed at instruments where blur is the problem: bass, 7- and 8-string guitars, and down-tuned six-strings1. If your low notes smear as they pass through a pedalboard, this is the kind of circuit Providence built to firm them up.
Power and connections
Power is the one practical wrinkle. Providence states: "It needs to be used with external power supply when 9V battery is used. It also runs with AC adapter or power supply."1
A 9V battery alone will not run the Vitalizer BF: Providence specifies external power whenever a battery is fitted, and the pedal also runs from an AC adapter or power supply1.
Price and availability
Premier Guitar reported at the March 11, 2016 introduction that "The Vitalizer BF pedal carries street prices of $119.00" in the United States2. Providence said the pedal would be available at select retailers, at EMG Pickups, and directly from Providence AMERICA's online store2.

Questions
Is the Providence Vitalizer BF VZF-1 a buffer or a preamp?
Providence calls the Vitalizer BF an Active Impedance Converter for Bass. Premier Guitar's announcement describes it as one of the buffers that converts a high impedance signal, so it sits in the buffer camp rather than being a preamp, though it is an active circuit rather than a passive one.
Can the Vitalizer BF run on a 9V battery?
Only with a catch. Providence states that it needs to be used with an external power supply when a 9V battery is used, and it also runs with an AC adapter or power supply. Plan on external power either way.
Does the Vitalizer BF work with 7-string and down-tuned guitars?
Yes. Providence says the Vitalizer BF tightens up the low frequency that tends to be blurred with bass, 7/8 string guitar, and down tuned guitar, so it is aimed at extended-range and low-tuned instruments as well as bass.
How much does the Providence Vitalizer BF cost?
At its 2016 introduction, Premier Guitar reported a US street price of $119.00 for the Vitalizer BF pedal.
Where can you buy the Providence Vitalizer BF?
At its launch, Providence said the Vitalizer BF would be available at select retailers, at EMG Pickups, and directly from Providence AMERICA's online store.
