Pros:
- massive construction, good quality knobs and switches
- classic sound, can be clean or distorted
- cheaper than AMS Neve
Cons:
- no signal led (you have to check your interface to see whats going on)
- the TRS input can only be a Hi-Z input, it can't be Line
- the Trim pot is from -5 to +5. If you want to drive it, you need an external attenuator (AMS Neve is from -20dB)
- there is no specification written on IGS's homepage, the manual is just a brief figure (that shows a non-existent signal led!!!)
Overall: It's not much cheaper than AMS Neve, it has the classic sound, but as I've mentioned, there are some annoying deficiencies
