The Bogner Ecstasy guitar amp head was designed to breathe like sweet old amplifiers-all living in one box. The standard features allow the "DNA" of the 3 distinctly voiced channels to be radically morphed into sounds of the past, present, and future. The Ecstasy tube head comes with EL34 power tubes and by using the footswitch, you can access 6 tuned variations of these channels instantly. Imagine going from Bogner's notorious barking Plexi mode to the greasiest, harmonically chewy overdrive . . . then washing it all down with the most decadent clean tone. The Bogner Ecstasy amp head comes standard with an amazing array of controls: 1/2 power switch, Old/New style switch, 3-way Excursion switches to control speaker cabinet dampening, 2 presence controls (one assignable), gain boost, Plexi mode, Structure, 3 Pre-EQ switches, tube buffered series/parallel FX loop.
