"Truly Epic"
Okay, first off. I don’t think I’ve ever received gear as fast as I did from zZounds. I have never used them before and I am now going to use them for anything they carry. Literally got it the next day, I was so glad. A few months back, I bought an Arrow unit, I brought it on a trip and I really love it, I wanted some more power though and the Apollo X4 is perfect.With the Arrow unit and the Twin you only have one headphone out. So I was splitting a headphone jack between two different types of headphones and it just wasn’t quite right. I knew I wanted to use a portable unit for collaborating, so this truly was perfect for me. It has plenty of inputs, two headphone jacks, and it’s so simple to use. I had an Apollo 8p and I got the X4 and I’m glad I did. I know I’ll eventually get an X8p in conjunction with the X4, but for now this is all I need and it’s perfect. I’ve had this unit for about a month now and I keep loving it more and more.
