I just picked up drumming again after a long break. I was working on my double bass speed and control, but I noticed that after 140-150 bpm my old pedal (Pearl p932) had some significant lag, especially in the slave pedal. So I decided I should "go big or go home" and bought this monster of a double bass pedal. I did not realise that you could have the level of precision and control that this pedal offers. I've only had it a few weeks and already my technique has improved two-fold.
The only downside is that the beaters aren't centered so you have to fiddle a bit with fixing it to your bass drum pad. I don't have an acoustic bass drum so I don't know if there are any issues there.
