Once you've had a go on the allen and heath filters everything else seems rubbish! They can cut out as much as you want so its like all the eq knobs in one and I reckon it sounds better too. So with each filter if you have it all the way down it does nothing, if you turn it up a bit and it starts to cut out the bass, turn it more and you cut out the mid, turn it more and you can pretty much cut out everything. Nowadays I barely ever use the eq except when I want to reduce the mids and highs on a tune to give the other one playing more room, but other then that its purely the filters.
Trust me get a xone 62 or 92, they're a lot of money but they are more than worth it
