Ok I need a head phone amp or I guess not need one but would like to get one to use for practice late at night. I think it would be easier than trying to use a little 15w peavey practice amp I have since my big amp doesn't have a headphone jack on it. and having cords running to and from and fighting to keep them outta my way plus needing a extension on my already long head phones cord. has anyone tried one or have one that they use?? what are your thought pros and cons?
