Sometimes I wonder how much Sonor's pedal reputation has to do with price? They're definitely not bad pedals and the docking station is not without merit if you don't use lots of different bass drums (I don't, so I love it). If the double came in at a $400-$500 price range they would be more widely used and probably get better reviews. The high price point puts expectations through the roof imo.
And back to the OP. Does anyone have any more info on what exactly is new about the Axis pedals other than the 21 degree thing and footboards? Oh, and it has a cool new Dr.Evil "Laser" name now.
