Benefitting from Joe Satriani's years of experience and built to his specifications, the VOX Big Bad Wah is a dual-mode pedal with switchable access to two wah modes and unique features for a wide range of wah sounds. Satriani contributed numerous ideas that were unheard of in existing wah pedals, endowing the Big Bad Wah with an unparalleled range of sounds from vintage to modern, as well as controls so users can create their own unique sounds.

Wah One faithfully replicates classic VOX wah sound, albeit hot-rodded to Joe's specs. Wah Two delivers all the wah-pedal know-how that Satriani has accumulated over many years, as well as the ability to customize your own wah sound. The Drive knob mimics the Wah 1 gain at its lowest setting; at its highest, it delivers a 10dB boost for aggressive, growling overtones. The Voice switch instantly takes you from traditional wah voicing to a dark, resonant tone reminiscent of a vintage talk box.

The Big Bad Wah also allows you to select between a vintage, U.K.-style inductor, and the more modern USA style. Also features a custom pot designed specifically to Joe Satriani's specifications to deliver a smooth, musical tone throughout the entire sweep of the pedal.


  • Dual-mode design offers 2 distinct wah sounds in a single pedal
  • Wah One is classic VOX
  • Wah Two provides Joe Satriani's original drive and voice controls for a wide range of sound-creation possibilities
  • 2 selectable inductors (USA and U.K. styles)
  • Controls: Pedal Controller, Drive Knob, Voice Switch, Inductor Select Switch, Wah 1 / Wah 2 Switch
  • In/Out: 1/4" Input, 1/4" Output
  • Power: One 9V manganese battery (6F22, included) or AC adapter (not included)
Pro Coverage
One year parts and labor warranty.

JS Vox Wah

By Alex Garcia

from Selma, CA

I had a feeling about this wah from the first time I saw it and I was right!! This thing is great!! Best affect I've ever bought. Channel one is a pretty standard Vox sound with a little more bite, channel 2 is great, two different voices for lots of sound. The sweep on any setting is very smooth, no bogging out. Satch knows his effects.

I hate to say this is the BEST WAH ever....

By darkhorse

from N Dallas TX

but seriously, seriously, THIS IS THE BEST WAH, EVER!!! Some things you should know, maybe not made clear in the info on this pedal. This not a hardwired bypass pedal BUT that is just fine in fact IT'S BETTER! Any experienced, player or tech knows, or should know, that although hard wired bypass is essential for your board and signal chain, you simply need a good buffer circuit which deloads your line and shifts it to low impedence stopping signal loss and keeping the tone as it should be. A fine point of this wah that apparently Vox is shy on stating because most players are no so bright to understand buffer circuits are as essential as bypass wiring, it is the combination that is the best! Put this 1st in your chain or board like Joe does and it improves your tone before you kick it on. On to the WAH: 1.) Two Wahs in this pedal foot switch, selectable even playing live 2.) Mode 1 is a great Vox tuned Wah and mode 2 is a mod Wah w high performance options. 3.) Both UK and USA switchable Inductors on either wah 4.) Mode 2 wah adjustable gain up to 10bd boost. 5.) Switchable voice on either wah bright std or darker Basically you can set a std Vox Wah w either inductor and then stomp over to a boosted wah with a different voice or boost, really, really amazing. This wah is the best most musical wah I have ever owned, the pot is tuned perfectly, the travel is short but a good sweep in tonal range. Smooth, responsive, tonal, musically useful in all modes and options. I have all the Vox Satriani pedals for a good reason they are the best tone boxes I have ever had. I was stuck on the optical circuit no pot wahs for years and this is my return to the pot wahs and this is soooo much better tone!

Best Wah Out There

By Luke Hudson

from Kennesaw, GA

This was my very first pedal. I saw it online and noted that this was one of the few where you could customize your own sound. The ability to customize is the highlight of this product. Wah 1 is reserved more for quiet or soft sounds while Wah 2 is for louder or more distorted sounds. Each then can be adjusted by the drive knob, which can make it sound somewhat muffled, the inductor, which makes the sound more vibrant, and then the toggle switch, which allows for "growling wahs" or "merry wahs". Whether you've never owned one of these types of pedals before pedal before or if you've gone through several, always pick this one as your wah of choice.

update on options

By paul

from McKinney TX

Should be clear that only the inductor choice option works on both modes and this is a blanket change, it effects both wahs, one or the other inductor. The Voice option does not alter the mode 1 wah. Both inductors and the voice option sound great and have their uses. This feature makes this wah worth having, like the MXR CAE wah with two inductors. The issue you can set a std Vox Wah with either inductor as mode 1 then footswitch to a mode 2 wah (during performace) having a different voice or boosted as much as 10db is over the top tone for solos or a real dynamic bridge passage. The pot is first rate, smooth, responsive, you can tell Joe voiced this wah as no matter what mode or option you try it all sounds extremely musical and quality tone. I have this (like Joe) 1st in chain, into my Whammy (used for harmonizer effects not the weeeoooo thing), this into the ICE 9, then into the Satchurator. The TimeMachine is in the loop before the Lexicon reverbs on the Hardwire RV-7, really brings on the tones. Occasionally I add a more intense gain box after the Satchurator for severe metal meltdown. But in general the Satchurator and the ICE 9 do it all using different levels of tube gain. Great pedal, you cannot go wrong with all the Vox Satriani boxes nothing in recent times has gotten me excited about playing again. I hope to buy another entire set of them and save them in the boxes.

Darn mechanical squeaks

By Ron S

from San Diego, CA

I wanted the best wah wah pedal and money was no object. As this was one of the most expensive I thought I was getting the best. Trouble is this pedal has such an annoying mechanical squeak that unless you play with headphones (or very very loud) it will be annoying beyond belief. I tried various lubricants and silicon grease and it did not eliminate the squeak. The squeak is so annoying that I am buying another pedal. Apparently this is not an isolated incident -- there are some videos on You Tube from other people having this problem.
