What are some good pedals for me. I'm into Alternative rock and Grunge like Pearl Jam and Nirvana (Nirvana more then Pearl Jam). So far all I have is a Original Crybaby Wah-wah pedal (I love that thing :)) and a Little Big Muff pedal. I was thinking of getting a BOSS DS-1 Super Overdrive Pedal, BOSS DS-1 Tremelo Pedal, and a BOSS DS-1 Flanger. I forgot if all of those are DS-1's or DS-2's. Any suggestions for pedals besides those that would be good for me?
