I know that this is a broad question with not a lot of info but any thoughts will be appreciated. A friend and prospective bandmate has asked me to learn some 70s funk songs (Rubber Band Man and Disco Inferno) for a set he's putting together. I think these are pretty much effect free but that some other pieces of the era were playing with some effects. If it really does get serious which effects should I consider adding to my board? I should add that the covers will not be note for note. My current board has a tuner, Big Muff (black Russian or reissue, I have both), MXR Bass Distortion, octave and Markbass Compressore along with a few less used pedals like phaser. This leads to the question: Which effects do you consider essential to covering the 70s fingerstyle funk bass sound? I'm considering an envelope filter but really have no idea what else I should consider. Yes, I've searched but not found much useful info...could just be my search skills suck tonight. Thanks for your time.
