Millenium PD-669 Stage Double Bass Pedal

Such badly produced staff should not be given away even for free. No tilt adjustment of beaters. Hand grinding the central roller is a joke. Especially the left one.
No balance adjustment of beaters.
The left beater is clearly slower and nothing can be done about it.
The shape of the attachment to the drum does not fit large sizes 20 "and larger.
Dent in the drum frame. Too light beaters prevent playing at full range of rates and forces.
Inertia is very specific and you won't play blues on this pedal.

After a hard and long setup time with the thing constantly falling apart, I finally got it to work. While playing, the pedal would always come loose at some point.

It got to a point where the hinge mechanism that is supposed to keep the pedal on the base totally broke off.

I think this was a refurbrished piece, I won't be ordering Millenium pedals anytime soon...
