OK, so far I have a wah-wah and a big muff. I know, I know, Tom Morrello will be afraid of me with my vast amount of effects available!!! Anyway, both are good pedals and I've sort of mastered them - but what should I get next? I want to go for a sort of funk/rock sound, but I do a wide range of styles. Compressor? Octave? Chorus? Envelope filter? Phaser? Anything else? All comments greatly appreciated.
