The Bogner Atma is a great-sounding, three-channel lunchbox amp with impressive versatility, with selectors for high/low gain options on every channel. Many players even refer to it as a “mini-Ecstasy,” which is fitting in more ways than one. The EZ81 tube rectifier is a nice touch, adding an extra bit of vintage response to the sound, and is also switchable with a SS diode type.
Like many lunchbox amps, it features selectable wattage—18/5/1W—making it suitable for everything from stage use to bedroom use. A standout feature is its aluminum construction for both the head and cabinet, giving it exceptional durability while keeping it surprisingly lightweight. Both pieces are in very good condition, showing only minor signs of previous wear.
