Bogner Mephisto Tube Set
The Bogner Mephisto Tube Set consists of 4 x 12AX7 preamp tubes, 2 x 6L6 power tubes and 2 x EL84 power tubes.
Two vintage voiced Class-A amplifiers are at the heart of the Mephisto. One is a 50’s American 6V6 and the other is styled after a pentode preamp based British EL84 and offers a total of 20 watts. You can easily switch between each amp or, and this is where the Mephisto’s shaping comes in, mix and blend them together for a huge range of unheard tones. And in combination with the switchable power attenuator you have a total of 5 sounds on tap via the foot controller.
Your guitar input is shared and then splits into the two independent amplifiers with their own individual pre amp, phase inverter and power amp. The two amplifiers then merge, after their power tubes, into one output transformer and speaker output.
