So I was looking for an alternative to the Waves API 560 (mainly because I hate paying the update prices) and this thing fits the bill perfectly. I've also used the IK Multimedia 560 and it's not bad but the scale of the EQ bands seem a bit heavy handed for me. The other features I enjoy about this guy are the mid/side functionality and the fact that there are two different analog harmonic distortion modes to choose from. Also you can disarm this completely. I've always enjoyed using the 560 on toms and this one does not disappoint. I highly recommend it.
