From Vertex:

The Vertex Boost is expertly crafted to be a clean boost, buffer, and volume pedal in one. The Boost is designed to leave your tone unchanged, while boosting the level of your signal. The Boost also features an ultra-linear buffer to condition your line with ZERO tonal coloration, even with dozens of pedals in your chain. Additionally, you have total volume control by connecting the Boost with any EXP pedal or Volume Pedal (with insert cable adapter shown below) and adjusting your volume as you would with a volume pedal. When the Boost is OFF, the EXP will function as a typical volume pedal (sweeping from silent to unity gain). When the Boost is ON, the EXP will control the boosted volume (sweeping from silent to wherever the level knob is set). Since your guitar signal is completely isolated from the EXP pedal, your tone remains open and full-range, and most importantly, it feels like your plugged straight into your amp.
