The BiValve-30 is a Single-Ended Class-A amplifier head that allows for versatile tonal experimentation by switching between various octal-based power tubes, such as 6L6, EL-34, and KT-66, without the need for re-biasing. You can mix and match any combination of output and preamp tubes (12AX7, 12AT7, etc.) to achieve different sounds.
This amp delivers a range of tones from smooth and clear to aggressive overdrive, with a powerful output transformer for thick lows. It can drive a 4x12" cabinet while remaining compact and lightweight. The built-in Hot Plate® Power Attenuator enables full output distortion at any volume. Its touch-sensitive input circuit and reactive tone control section offer a highly responsive and dynamic playing experience.
