The Bogner Ecstasy Blue Mini captures the legendary Blue Channel of the Ecstasy amplifier, renowned for its classic Plexi-style crunch. It utilizes cascaded gain stages without op-amps or diode clipping, mimicking the circuit design of a vacuum tube amplifier. The pedal features controls for Volume, Treble, Middle, Bass, and Gain, along with three toggle switches for fine-tuning the voicing. These switches control Variac voltage simulation, Pre-Eq for harmonic definition, and Gain structure modes.
