The Vox V845 is a wah pedal, currently in production, that Vox describes as delivering "the unmistakable VOX sweep in a rugged, all-black chassis designed to handle years of rehearsals, gigs." Vox positions it as the workhorse of its wah range: "the same legendary Wah-Wah tone in a new sturdy but very affordable design"1. It runs on a single 9V battery, with an AC power connector fitted so an optional adapter can save on batteries1.
The Vox sweep
A wah pedal rocks the filter's frequency up and down under the player's foot, and the V845's selling point is that character: Vox calls it "the unmistakable VOX sweep"1. The circuit is not a new design idea. Vox states the V845 is "Based on the specifications of the original pedal developed by VOX in the '60s," and the circuit analysis published at GuitarPCB quotes the same description for the V8452. For a player, that means the V845 is the modern, affordable expression of the sound that started the whole wah pedal family.
Power and running costs
The V845 ships with battery power as standard: one 9V DC battery, which Vox rates at approximately 100 hours of life, with the caveat that this will vary depending on conditions1. An AC power connector is fitted to save on batteries, but the AC adapter is optional and sold separately, so nothing extra is needed to start playing1.
The AC adapter is not included in the box. If you plan to run the V845 from a power supply rather than a battery, budget for the adapter separately1.
Size and weight
Vox lists the V845 at 942 g, or 2.08 lbs, with dimensions of 102 x 252 x 75 mm, which is 4.02 x 9.92 x 2.95 inches in width, depth and height1. The all-black outer case is described by Vox as a tough coating on a rugged chassis built to handle years of rehearsals and gigs1.
Where the V845 sits in the Vox wah range
The V845 is the affordable workhorse, but Vox's wah line stretches well beyond it, and most of those pedals share the same 1960s ancestry1:
- The V847A is the closely related sibling; Vox publishes a single owner's manual, dated 11/14/2014, covering both the V845 and V847 wah pedals1.
MusicRadar reported the V845's announcement in September 2009 at a price of £57.003.

Questions
Does the Vox V845 take a battery?
Yes. Vox specifies one 9V DC battery for the V845. The pedal also has an AC power connector fitted, and Vox says this is there to save on batteries, but the AC adapter itself is optional and sold separately, so the pedal can run on a battery out of the box.
How long does a battery last in the Vox V845?
Vox rates battery life at approximately 100 hours, and notes that this will vary depending on conditions. Because an AC power connector is fitted, an optional adapter can take over from the battery for long stretches of use.
Does the Vox V845 come with an AC adapter?
No. Vox states that the AC adapter is optional and sold separately. The pedal does have the AC power connector fitted, so a compatible adapter can be added later without any modification.
What is the difference between the Vox V845 and V847?
Both are Vox wah pedals built on the specifications of the original 1960s Vox wah, and Vox publishes a shared owner's manual covering the V845 and V847. The V845 is positioned as the workhorse of the range, described by Vox as a sturdy but very affordable design in a rugged all-black chassis.
Is the Vox V845 based on the original 1960s Vox wah?
Yes. Vox states the V845 is based on the specifications of the original pedal developed by VOX in the 1960s, and the technical analysis at GuitarPCB quotes the same description.
