Wonderful! I really can not find anything wrong! I used it on my violin with piezo pick up in a recording studio. It gave me the natural, warm and sweet sound I was looking for, but it has the ability to make another hue. I was very satisfied with the eq and the filters helped me a lot in shaping the tone of my violin! Having a second channel is very helpful as you can combine the microphone sound at the same time. I have not tried it but I believe that the result will be even better. Also, xlr in helps with this. Excellent sound quality. It also provides a fairly strong signal. Strong DI. Very positive that you can handle each channel separately. You can also choose whether to use one or two channels! For me, it is a great quality tool. I do not think anyone has anything to fear from this! Perfect!
