Huge upgrade.

The Pearl P-932, also known as the Demonators, is definetely the best set of double bass pedals I've owned so far. I have tried multiple others, from DW to Tama. The demonators feature the same board as the more advanced Pearl pedals (Demon Drive). These do not wobble, they are sturdy and feel natural. Of course, everything is adjustable (springs, beater angle etc) and it can easily be turned to a single pedal. I must add that the drive shaft is made out of aluminum, allowing for durability and giving zero chance for any awkwardness in your playing on the long run.
