Query: A decent double bass drum pedal for the money

This is actually a pair of separate pedals, one with a fitting for an extra beater, and one which includes the extra beater and the link with 2 U-joints to connect the two. You could actually make 2 complete pedals out if it if you wanted. The whole thing seems to be very solidly constructed, and after a bit of adjustment, seems to work just fine. Now all I gotta do is actually learn how to play double pedals.
