The first time I played on a cry baby, I wanted it. Then I realized I wanted a wah with more versatility. I saw this, and I thought "that's the wah I want". You turn the Q dial fully clockwise and it sounds fatter and is good for distortion. I use an Ibanez SM7 so I'm amazed this wah keeps up with it. Then you turn the Q dial fully counter-clockwise, and you get a thinner sound with heaps of freq, and the other 4 selections in between offer every other sound. This wah is fully amazing, it brings a new meaning to the word 'wah'. The only two things that can annoy me are how it has no LED, but then again it isn't so important, and when you turn the wah off, if you leave the foot pedal pushed all the way down you won't be able to turn it back on until you've lifted the foot pedal up then back down. This allows the hard wire button to lift. So after I turn it off, I lift the wah all the way up, so that problem is out of the way. Aside from those two minor problems, Jim Dunlop and his team have created one of the best wah's ever.

Ordered in April, didn't receive until 29th July because it was not in stock, but it was well worth it. This really is the ultimate wah, from which you can create any wah sound you can think of, from any artist you can think of. The q-dial thing is the best modification ever, where in one turn you can go from a broad, volume-like wah to a narrow sharp wah, and all points in between.Absolutely recommended and extremely good value for money.

This wah truly kicks. The boost is VERY useful. the Q-dial gives it great versatility! it is a very good wah. I recommend it over any other wah.

Anyone who wants real wah, this is a great choice.

I play all different types of music, but mostly metal. This is one of the sickest wah's I have seen. I've tried them all, including the VOX V848 and this one takes them all. Although the V848 is good competition the 535Q is just too much wah to even make it close. When you look at all the different devices it uses and how extremely versatile it is, then there's nothing to even compare with these two. The boost Q-knob, volume control and distortion barrier controls let you use endless amounts of sounds, all of which are used by some of the greatest guitarists in the game, like Jimi Page, Hendrix, Eric Clapton, and more. Also a big problem I had with the Vox is that it didn't sit very well with most of my distortions that I have. At the bottom end of the wah, the volume got lost. The crybaby pounds out the wah under every type of effect I put it under.
