If your on a limited budget and don't use this too often, it will make a decent headphone amp. Sometimes I get a lot of hum in the background and sometimes not at all. Not sure yet what is the problem. I have this at my parent house so I can rock out without disturbing anyone. And for this purpose it fits neatly. Sound quality seems fine, and the choice of guitar really matters here. Simple little neat device. If you plan to use it more, I advice to spend a little bit more.
