OK guys, I'm looking for an envelope filter, octaver and distortion/overdrive and I have MAYBE $100-200 to cover everything. Obviously I'm going used. What are my best options in this price range?? I'm trying to copy the synth sound on the intro to Mr Crowley with the envelope filter and octaver and I just want a decent sounding distortion/overdrive to thicken things up when we dont have our second guitar player. The filter and octaver are the priorities-the distortion can wait a little while. Thanks in advance!
