I just picked this guy up today and I am very impressed. I went in expecting to get the Picture Wah but ended up with the WOF. The fattest, smoothest sounding wah I have ever heard. Not the best for the wikka wikka stuff but I don't do that very often and it does it well enough for me. The tweakabilty may come in handy too because I am likely to get bored with any piece of gear I own. Props to Mr. Teese! Now maybe there's a chance I could be content with my gear for a while once my Sunface comes in...right... Anybody else using this?
