The Valeton Rushead is a fantastic headphone amp. It's not as sophisticated as the Fender Mustang Micro or its clones, but it's also not as dull as many of those "single genre" two-button amps. In fact, I would say it is the perfect travel amp because, paired with good studio headphones, you can achieve most of the tones you would need to rehearse. On most presets, the sound is clear and the rubberized buttons are easy to maneuver. As negative points, I would say the lack of a rotating jack is an immediate issue and the fact that on some high gain modes, the amp does get a bit "hissy". However, for this price, I wouldn't count them against the amp.
