This is a new standard for bass preamplifiers equipped with vacuum tubes. Equipped with a 3-band EQ, the boost / cut frequency is <Bass: 65Hz | Midd: 500Hz | Treble: 4kHz>. Beyond’s unique frequency bands for various scenes.
Vacuum tube gain balance
Based on the 1: 1 clean tone at 12 o’clock volume, the optimum balance has been achieved up to the distorted sound pressure feeling at maximum volume. The even-numbered harmonics of the vacuum tube give the sound a glossy and three-dimensional effect.
Equipped with Electro-Harmonix vacuum tube (12AU7 EH).
Compact size while equipped with a vacuum tube.
Equipped with 3-band EQ <treble | middle | base>.
Acoustic capacitors | We use carefully selected parts such as metal film resistors.
True bypass switching method. When turned on, the LED under the vacuum tube lights up.
