As you plug this, you smile. I couldn't believe the difference between this and a "normal" dunlop crybaby. Astonishing difference in the quality of sound. Expecially if you're recording i nstudio, this is like having all the wah options in one box, which makes it really worth the money in a long run. Avoid having other wah until you try this one. The boost knob also colors the sound slightly, but it a way that really makes you smile, again! I also like the fact that I FINALLY have a led to know if the baby is on or off in live situations. Great pedal, worth ALL the money in my opinion, one of the best pedals available on the market today. I would only have put an even bigger led to signal if the pedal is on or off, as it might be confusing initially to discern if the on/off led or if the feasel yellow/red led is on. Apart from this really minor detail, if you're looking for a quality wah which is also a boos and gives you a wider palette of tones, buy it, you won't be disappointed.
