advice would be go try as many wah pedals as possible b4 settling for one. especially if its your first.
Don't end up like me....trying my first wah, thinking its good and buying on impulse b4 trying another and coming to the realisation that the one i bought wasn't the sound i wanted.
First time buyer blues.....try a shop that has a huge range of wah pedals not just carrying one brand, but a few brands so you can compare them side by side. Ebenex music and TY music, mrmisse just to name a few, they carry quite a few brands of wahs with different models.
