The Morley M2 Passive Stereo Volume is a passive stereo volume pedal from Morley's M2 line, announced in March 2014 at a US list price of $1301. Because it is passive, it does not need a battery, and it works for guitar, bass or keyboards1.
What it does
The pedal controls volume with what MusicRadar described as "a smooth linear taper that can be used for guitar, bass or keyboards"1. A linear taper means the pedal's travel maps evenly to the volume change, which players often prefer for swells and for keyboard or bass rigs where an even response across the pedal's range matters.
Its stereo capability is the other headline feature. As MusicRadar put it, "It has the facility for a single output to route two outputs simultaneously"1. In practice that means one input signal can be sent to two outputs at once, which covers running two amps, a stereo rig, or separate paths for different parts of a setup.
Design and build
The M2 line shares a common housing. MusicRadar described the pedals as "housed in Morley's instantly recognisable rolled steel housing"1, the steel construction Morley's pedals have long been known for. All the new M2 pedals carried a two-year warranty at launch1.
Because the pedal is passive, there is no circuit to power: no battery, no power supply, no current draw to plan around on a pedalboard1.

The M2 Passive Stereo Volume sits alongside the mono Morley M2 Passive Volume and the Morley M2 Wah Volume, which adds "a choice between Wah or Volume mode" along with "wah level control, True Tone buffer and LED indication"1. Morley's wider volume range also includes the Morley Volume Plus, the Morley Mini Volume and the Morley Little Alligator Volume.

Questions
Does the Morley M2 Passive Stereo Volume need power?
No. Because the pedal is passive, it does not need a battery or a power supply to work. There is no active circuit in the signal path, so it can sit on a pedalboard or in a keyboard rig without adding anything to the power budget.
What instruments is the M2 Passive Stereo Volume suited to?
Morley describes the pedal's smooth linear taper as usable for guitar, bass or keyboards. Its stereo routing also lets a single input feed two outputs at the same time, which suits players running two amps or a stereo rig.
