The Vertex Stereo Volume Pedal is a passive, analog volume pedal that works in stereo or mono. Vertex describes it as "the most transparent passive volume pedal available," designed to let "the organic tone and dynamics of your instrument" flow through1. Because it is passive, it needs no power supply or battery: the pedal simply varies the level of the signal passing through it.
The circuit is a deliberate simplification. Vertex states the design "simplifies the Boss FV-500 volume pedal platform to its fewest components," taking the approach used in the Boss FV-500H and Boss FV-500L and reducing it to the minimum parts needed1. The pedal is also "100% Handwired, Point-To-Point," meaning the components are wired directly together rather than on a printed circuit board1.
What it does for a stereo rig
In stereo, the pedal provides one treadle-controlled volume for two parallel signals, letting a player with a stereo amp setup or a stereo effects chain fade both channels together. Saturn Works, which builds a similar unit, describes the concept plainly: "The stereo passive volume pedal provides a single volume control for two parallel signals"2. The Vertex works the same way, and the maker specifies stereo and mono operation, so the same pedal can move between a stereo rig and a mono board without changes1.
For players comparing options, the passive approach differs from active stereo pedals in that there is no buffer driving the signal. Other stereo passive designs in the same space include the Morley M2 Passive Stereo Volume and the Lehle Stereo Volume, while players who want a powered or buffered stereo pedal would look elsewhere. Vertex also builds a mono version, the Vertex Mono Volume Pedal, for single-channel rigs1.
Construction and design
The point-to-point handwiring is the headline of the build. Vertex pairs it with the stripped-down FV-500-derived circuit, and the combination is aimed at keeping the signal path as short and simple as possible1. A product manual is available as a PDF download from the maker's site for players who want the full documentation1.

Reception
The pedal carries a 5-star rating across 4 reviews on Vertex's own product page1. For context on the wider category, see the site's Volume Pedals page.
Because the pedal is fully passive, it presents the potentiometer's load directly to whatever feeds it. Players running it straight from high-impedance guitar pickups, rather than after a buffer or drive pedal, may hear the interaction that is typical of any passive volume pedal.

Questions
Does the Vertex Stereo Volume Pedal need power?
No. The pedal is 100% passive and analog, so it does not need a power supply or battery to work. Because there is no buffer or active circuitry, your guitar's signal passes through the pedal's contacts and potentiometer directly, which is why Vertex describes it as transparent and able to let the instrument's organic tone and dynamics flow through.
Can the Vertex Stereo Volume Pedal be used in mono?
Yes. Vertex specifies stereo and mono operation, so the pedal can sit in a single signal path with one input and output, or control two parallel signals at once in a stereo rig. A single volume control handles both channels, in the same way other stereo passive pedals provide one control for two parallel signals.
Is the Vertex Stereo Volume Pedal handwired?
Yes. Vertex states the pedal is 100% handwired with point-to-point construction, meaning the components are wired directly to each other rather than mounted on a printed circuit board. This is a build choice aimed at signal integrity and easy servicing rather than a difference in how the volume control behaves.
Does the Vertex Stereo Volume Pedal have a warranty?
Yes. Vertex offers a lifetime warranty on the Stereo Volume Pedal, according to the maker's product page. That covers the pedal for as long as the original owner has it, which is a common assurance on handwired pedals but worth noting because passive pedals have few parts to fail in the first place.
