Hmm, i would say you should get a wah pedal if you play rock/metal for those solos, a distortion pedal for rock/metal or if you dont play rock/metal, go for an overdrive pedal, delay, reverb or chorus pedal. I recommend boss pedals, and if you're going for the wah pedal - go for a cry baby, i have a 53Q (the latest model) and it's awesome - very versatile. Enjoy!
