1. Versatile Sound: The 15W Tube Guitar Amplifier Head features two preamp stages controlled by GAIN/VOLUME knobs, delivering clear tones to OverDrive sounds. With 1W/15W switch and high/medium/low EQ controls, it offers a wide range of sound customization for different needs.
2. High-Quality Handcrafted Output Transformer: The output transformer is handcrafted with a paper insulation process, which reduces stray capacitance and increases resonant frequency, leading to better high-frequency response and transparent sound. The use of Grain-Oriented Silicon Steel (35Z155-0.35) increases inductance and improves low-frequency performance.
3. Single-Ended Output Stage: The Single Ended Output Stage provides a clean, stable, and moderately powered sound, which is perfect for each player's use.
4. Durable Aluminum Casing: The amplifier head is housed in a sturdy and stylish cast-aluminum casing, ensuring its durability and aesthetic appeal.
5. Convenient Controls: The amplifier head features easy-to-use controls including a single channel, 1 x 12AX7 (ECC83) preamp tube, 2 x EL84 power tube, along with knobs for volume, gain, high, middle, and low, and output jacks for 8Ω/16Ω.
