The scene at my local Best Buy customer service counter, the day after Christmas:
What you don’t seen is the woman in line behind me, also with a set to return. I would suggest holding off on Guitar Hero World Tour. Alternatively, pick up a copy of Rock Band 2 like I did after returning mine! :-)
(mine’s the one on the far left)
UPDATE: There appears to be an issue with the placement of the sensors on the cymbals that you can fix with a combination of the RedOctane GHWT Drum Tuning Kit and perhaps a manual relocation of the sensor inside the pad. I’m pretty sure the price of the full kit just dropped from $189 to $159.
