Question about the PDP BOA pedal

Hello,
I'm new to this forum. Anyway, I just ordered the single BOA pedal and was wondering if anyone knew whether or not there is a slave drive addon or whatever it's called to upgrade to a double bass pedal. It's not extremely important that I upgrade, but it would be nice to know for future considerations.
Thanks

To my knowledge, no add on. You'd have to buy a BOA double-pedal, like here: http://cgi.ebay.com/NEW-DW-Pacific-...rum-Pedal_W0QQitemZ390027251297QQcmdZViewItem Welcome to Drummerworld.

Does anyone, beside this Ebay store, sell them? Cause i cant find them anywhere. Its a really nice pedal too.

The only store I've walked into and seen one is Pro Drum, here in Los Angeles.
