Ok so I bought used PDP 402 double bass pedals from Guitar Center (probably should have bought new ones) and no matter what I do with the tension the left pedal has to be hit harder and the left beater is further away from the bass drum, the beaters aren't lined up, I don't really know how to explain it and the left pedal squeaks, should I go return it? Ask me questions so I can get help, I want both beaters lined up with the same tension.
