My wife's trying to pick me a gift for xmas. And as much as I would like to put a guitar on the list...well, I don't need another and in the end, I'm paying for it. So a nice little stocking stuffer would be a fun pedal. But I have no idea what I need. Can you guys help me? I have a wah, an overdrive, a fuzz, a delay and looper. I don't really know what I am missing but would love something I've never had but MUST have. Reverb is on the amps, so what are your top 3 that I need that I don't already have? What is a game changer? Chorus, flanger, phase, compressor, something more exotic? I play rock n' roll mostly.
