Overview

Rich tube tone in a size that works from the bedroom to the stage.

The Bugera G20 Infinium 20W Class-A tube head brings you the rich, warm tube tone and natural compression of a vintage amp in a modern, portable design. With 20W of all-tube power from two EL34 power tubes, the G20 delivers harmonically rich clean and overdriven tones perfect for everything from jazz to classic rock to modern metal. Its two preamp stages give you independent tone-shaping for pristine clean and saturated overdrive sounds, while the 3-band EQ with Morph control lets you sweep between classic British and American EQ curves. Topping it off is a lush built-in reverb that adds dimension to your tone.

Keep the Tubes Singing With Infinium Technology

Bugera's Infinium tube life multiplier technology lets your tubes sing for up to 20x longer than conventional amps. It actively monitors and balances the load across output tubes so they wear evenly. Infinium extends tube life by compensating for aging and automatically adjusting current levels when AC line voltage drops. You'll save money on expensive tube replacements, while Infinium preserves your tone by keeping tubes performing like new.

Class-A Design Delivers Vintage Tone

The G20 utilizes a classic Class-A design with two ECC83 preamp tubes and a push-pull EL34 tube power amp. This all-tube design provides the lush even-order harmonics and natural compression that make vintage amps so sought-after. From warm jazzy cleans to smooth overdrive with vocal-like qualities, the G20 nails those classic tones while weighing in at just 22 pounds.

Get the Best of Both Worlds With Morph Control and Reverb

The G20's 3-band EQ includes a patented Morph control that lets you continuously sweep between classic British and American EQ profiles. Sculpt tweed-era Fender cleans or Marshall-style overdrive at the touch of a knob. The Morph control makes it easy to dial in the perfect tonal balance for your guitar and playing style. The built-in reverb adds dimension and space to your sound, with a smooth decay that complements both dirty and clean tones.
