This is one bad-a** EQ, Finished my build and tested, and I'm finally achieving those buzz words we all use too much, but finally, I get why!! Fat lows, thick mids, and silky high end. The real deal. Wasn't an easy build, but the interactive build guide was super well put together, follow it, and you'll be fine. Will definitely be getting a second one day. (Sat May 07 2022, 11:44 am )
