The Little Labs I-VOG Analog Bass Resonance Tool is a standalone version of VOG but with a hi quality hi Z instrument input for added creative capability. It was originally designed to capture the chest resonance of vocalists or voice over artists, enabling them to still have a proximity type effect without having to be so close to the mic.
 
The Little Labs I-VOG Analog Bass Resonance Tool is identical to the VOG, but adds an instrument input, which has a 3.32 meg ohm input impedance and adds 10dB of gain. The instrument input is especially neat for passive instruments, and adds to the Little Labs I-VOG's creative capability. The Little Labs I-VOG also has both XLR I/O and TRS I/O. The Little Labs VOG was originally designed to capture the chest resonance of vocalists or voice over artists, enabling them to still have a proximity type effect without having to be so close to the mic, hence the name, Little Labs VOG, or Voice of God. However, when you hear it on kick drum and bass, it will become clear this would be the go to device to make these instruments sound huge. The VOG lets users sweep a sharp peak resonance from 20 to 300 Hz, while anything below the peak is rolled off at a steep -24dB per octave. This lets users focus on the low end they want, while eliminating low-end mush and unnecessary woofer excursion.
 
A subharmonic can be the focus, or the fundamental, or upper harmonics. On a kick drum, for example, the overall effect of turning Little Labs VOGs frequency knob sounds like someone is tightening or loosening the drum head. In a mix, Little Labs VOG allows users to place the bass spectrum instruments so they do not interfere or get in the way of each other. The Little Labs I-VOG is identical to the VOG, but it's a standalone version, no rack required.
