I've had this a long time now so am in a good position to review it.
As mentioned in some of my other reviews, I record in a very small, weirdly shaped room that generates many short reflections that colour the upper middle quite nastily. Acoustic tiles calmed that down.
But a standing wave also created problems, especially when mixing. That wave is on the note A - bad for us guitar players.
I didn't expect the Basstrap to do much but needed something badly.
I was surprised at how much of that standing wave was soaked up by this device. It is really quite effective.
Not all of the problem has gone but enough to make mixing viable - and that is worth the money alone.
While it is aesthetically 'interesting', it is also big and heavy. It doesn't dissolve into the background of a small room.
That said, it is good for parking lyric sheets, watches, phones etc.. while getting on with recording.
