Overview
  • 1Description

The 333 INFINIUM 120-Watt Tube Amplifier Head features a hand-made three-channel design that can produce up to 120 watts of power. The Clean, Crunch, and Lead Channels all have independent gain structures, as well as their own Volume, Bass, Mid, and Treble control knobs. The amp also includes a Master Volume control knob. The preamp section features four 12AX7 tubes, while the power section is driven by four 6L6 tubes (convertible to EL34s).

Additionally, the 333 INFINIUM is built with Bugera's INFINIUM Tube Life Multiplier Technology. It is designed to lengthen the life of your tubes, and optimize their output by dynamically balancing the drive between them to evenly distribute the load. When you do need to replace a tube, the system will indicate which one with its back-panel LED indicators.

The amp also comes with an effects loop that has adjustable Send and Return levels, as well as a boost feature, which provides added volume to any channel when engaged. It has built-in reverb and two 1/4" speaker outputs with selectable four-, eight-, or 16-ohms for driving external speakers. You can navigate the three channels with the included footswitch, which can also engage and disengage the effects loop and boost. A 1/4" rear-panel line output can be used for recording to your DAW.

Three Channels of Tone
The Clean Channel is designed to provide no break up for jazz, country, blues, as well as providing a base for using external distortion stomp boxes. The Crunch Channel is optimized for rock and blues, and can produce metal tones with the gain cranked. The Lead Channel is similar to the Crunch Channel, but with more available gain
Damping Switch
The Damping Switch adjusts the resonant frequencies of the speakers, providing different tonal options
