Description

The Bugera G20 Infinium Head is a powerhouse of tonal versatility for guitarists seeking dynamic range and durability. This 20-watt Class-A tube amplifier head comes equipped with Bugera's innovative Infinium technology, a game-changer that extends the lifespan of your tubes up to 20 times while ensuring optimal performance. Whether you're crafting smooth jazz, gritty blues, or hard-hitting rock, the G20 delivers with its rich harmonic content and natural compression.

At the heart of the G20 is the Morph control, a feature that allows you to effortlessly blend between classic American and British EQ curves. With this, you can seamlessly shift from warm, full-bodied tones to bright, chimey sounds, making it a versatile choice for any style or setting. The built-in reverb adds lush depth to your sound, enhancing both clean and overdriven tones with a touch of ambiance.

Designed for flexibility, the G20 includes an effects loop with a level switch for integration with your pedalboard or line-level effects, and a speaker-emulated output for silent practice or direct recording. A two-channel design with independent controls ensures you can easily switch between pristine cleans and saturated overdrives, making it as adaptable on stage as it is in the studio.

Key Features:

  • 20-watt Class-A tube amplifier head
  • Infinium Tube Life Multiplier for extended tube lifespan
  • Morph control for blending American and British EQ tones
  • Two channels with independent tone-shaping
  • Built-in reverb for added dimension
  • Effects loop with level switch
  • Speaker-emulated output with 1x12 and 4x12 voicing options
  • Impedance selector switch: 4, 8, 16 ohms
  • Includes footswitch for channel and reverb control
