Tube Amplifier Mio Amply

Architecture and Power:

• Circuit: Entirely tube-based, hand-wired (Point-to-Point) on a polycarbonate structural board, operating in pure Class A Single-Ended configuration.
• Maximum Power: 5W (purposely optimized for maximum tone shaping and saturation, not for pure acoustic power).
• Power Attenuator: Integrated switch to toggle the power tube from Pentode mode (5W) for an incisive and articulate sound, to Triode mode (2W) for an increase in low frequencies and a softer, more harmonious saturation.

Preamplification and Control Stages:

• Preamp Tubes: 4 preamplification stages equipped with two 12AX7 (interchangeable with 12AY7 or 12AU7 to modify gain and frequency response). The fourth stage works as a unity-gain impedance adapter for the equalizer.
• Tone Shaping Matrix: Configurable switches that modify the behavior of internal components in real time:
  • Cathode bypass capacitors: High values for linear gain and extended distortion, reduced values for distortion focused on mid frequencies.
  • Anode output capacitors: Act as filters on low frequencies (high values to give body, low values to tighten the response).
• Gain Cut Switch: Dedicated selector to exclude the second half of the first tube, transforming the circuit into a crystal-clear, high-dynamic Clean channel.
• Custom Equalizer: Inspired by the historic Marshall response, fully customizable in frequency tuning via proprietary software.

Power Section and Unchanged Bias:

• Power Tube: Supplied standard with a compatible pentode, replaceable without the need to adjust the bias (Autobias) with any power tube on the market (such as 6L6, EL34 and compatible models) to customize the dynamic response.

The Innovation: Integrated “Mio Pedal” System:

• High Voltage Tube Booster: Housing for booster module powered directly by the head at high voltage (260V DC) to ensure real and uncompromising dynamics. Available in two interchangeable variants:
  • Pedal Circuit 1: Common cathode configuration with strong filtering of low frequencies and second stage in Buffer mode. Transforms a crunch channel into a surgical and defined high-gain.
  • Pedal Circuit 2: Two active tube stages in cascade for progressive gain, natural compression, and a monumental harmonic saturation.

Modular Configurations and Digital Integration:

• Head + Cabinet Version: Boutique cabinet equipped with two distinct speakers (Celestion Greenback and Jensen Alnico), instantly selectable on the fly via a dedicated switch without rewiring.
• Sound Shaper Version: Configuration without cabinet with integrated Load Box (dummy load) for direct recording in high-resolution DAW.
• Proprietary IRs and NAM Profiling: Inclusion of stereo Impulse Responses sampled from GB Liuteria boutique cabinets and the digital library generated via Neural Amp Modeler (divided into Clean, Crunch, Overdrive, and High Gain categories).
• Custom Aesthetics: Design completely customizable on request with Vintage/Boutique finishes, or in aluminum and selected leather.
