This is so easy to use. Plug the left side into your cab and the right side into your guitar or chain some pedals together. Without a doubt a super great sounding amp at $100! EHX is by the far the best when it comes to crazy new ideas that actually work. I’m using a Holy Stain for reverb and fuzz through the 22 Caliber. Done. You can look up some demos on Youtube from the Namm show. It’s really loud and has a very tube like tone. I’m also playing though a 1X12 cab and the sound is so tight and punchy. What else could you possibly want?
