I've owned a pair of Pearl double pedals for years and yet I haven't had a case/bag for them, I've always borrowed one from a friend or worse just carried them in a duffel bag.
Now that I have finally bought myself a pedal bag I have to admit that it is just amazing being able to carry them easily without a fuzz and comfortably too.
This bag is also a real space saver!
Despite being a load cheaper bag that its competitors this Millenium pedal bag for double pedals is really - I mean really well made.
My only complaint would be the carrying shoulder strap that it comes with - A little wider or more padded strap would be more comfortable for the end user, especially on longer carrying distances to gigs or practise.
But regardless it's not a big enough "fault" to drop a star off the rating since this bag really outperforms others with its value for money and the overall quality and "not feeling cheap".
In short, it fits your double pedals, its driveshaft, your beaters, a drumkey and an assortment of drum hardware related miscellanea such as bolts and washers.
