I have the EBS Stanley Clarke. I definitely prefer it to the 105q. Word of warning, though, I've had this thing for a little over a year and have had to fix it frequently. The pot pulled out of the wah after about two rehearsals, the paint started chipping off pretty early on, and recently I ended up trading out the crappy little plastic retainer that they provide to hold the gears together for a more substantial one I salvaged out of an old Bass Crybaby because my gears kept slipping. I'm pretty easy on my equipment, definitely not cranking on anything.
If you want the best SOUNDING wah I would point you towards the EBS, but I'd warn against the shoddy construction. For the money you could buy two different wahs that would probably satisfy you nearly as much.
They're kinda pricey too aren't they? I think EBS makes some great stuff. But I too have had issues with the couple things I've owned from them. Shoddy is the word. The patch cables they make now are the best thing I've ever used from them. Just sayin. For $250 brand new, I'd expect it to last quite a while before I had issues like that with it.
