Thing is, a wah is a pedal... just like any other pedal, its got to be connected the "right" way.
You got 2 things that don't change - Guitar & Amp.
Guitar ------------ Amp
Whatever is inbetween, it is up to you, in whichever order you prefer OR whichever order works best.
So a wah... usually, wah's come first in the chain. So after the guitar, let's put the wah there. Then you stack on everything else... dirt, modulation, delay, etc etc and what do you end with? The Amp.
So experiment. I can assure you, it is not rocket science... and I'm not doubting your ability - everyone has a first time. Just take your time, plonk the wah in different places, till you think you got something nice.
Now, on to the wah itself. How does it work? You seem to know, rock it back and forth. Correct? Use it on clean... the extremes seem to cut off a lot of treble/add vol/other un-necessary, un-likeable stuff. The 535Q is an immensely tweakable wah - go tweak. Read manuals. Search reviews online... yadda yadda.
You'll find some things:
1) Some settings work on cleans, but seem a little weak on dirt
2) Some settings don't work on cleans, but work nice on dirt
3) There are yet some settings that seem to capture the best of both worlds but... its just not "IT" in either case.
Again, this isn't rocket science. Don't worry, don't be afraid to tweak - in fact, spend the time to tweak. An hour. 2 hours. Just sit there and play.
*Hint* Stick to either clean or drive, then tweak the wah till you find some nice settings.
Remember, the wah is an EXPRESSIVE thing - recall that Sweet Child solo. What does the wah remind you of? A human... singing. That's the thing. You need to be able to control the wah so it is able to express itself, like how we sing, like how we word things. Except its with a guitar this time.
So, since it is expressive, you can't sit there, turn the wah on, then leave it in one position right?
As you toe down on it, you get a "wahhhhh" and it gets more trebly, more pronounced at the end of the sweep. Lean back and you get a more "ooooahh" kind of bassy thing... so work that wah as you tweak.
If you don't know how to wah, then simple, do it like kirk hammet first. Just rock the wah back and forth in a fixed rhythm.
Thereafter, when you get better, its time to explore making vocal expressions out of your guitar...
