I have been mentioning to the guy at BYOC to look into a PQ-4 clone. I don't know if there are any plans for a kit, but if I hear anything, I will be sure to let everyone know...
I remember them when they came out,but i also remember the guy in one of the music shops telling me i was better off sticking with my GE-7 for acoustic stuff....
a lot of boss pedals are up right now about $100 more than they were a month or two ago.
2 months ago i picked up a DM-3 locally for ~$160 and DM-2 and DM-3 were going on ebay in the $150-180 range w/ BIN's ending with 0 bids @$185.
now i see they're in the $230-280 range, so i'm guessing that the PQ-4 going for way high isn't all that unique.
a lot of it probably has to do with people getting their income tax returns back and looking to buy stuff... whereas if you're like me and owe taxes then you have to sell stuff :P
