I think its also a sign that the guitar market here is maturing. Of all the people here in soft, u have to wonder about the percentage of home musicians, studio musicians, giging musicians (includes those who play at church or other religious organisations.)
With those who just play at home for fun, nowadays $200 can get u a reasonable practise amp with most of the effects you'll ever need.
For those who gig, or just play with friends in the studio, most will have got all they need after about 2-3 years of experimentation. Then most will realise, more often then not its not the pedal, its the amp. Many drives/distortions in the market sound similar anyway. Then u tend to think twice before u go out to replace an existing pedal from your board.
I also believe theres an increasing number of people using multi effects and this will take its toll on the pedal market. More so when churches are increasingly going towards the ampless route.
The bad economy at this time may contribute a bit as well.
Hmm maybe wait until early jan to sell your stuff after people get they're 13 month?
