The 333 INFINIUM is a cutting-edge, modern-style tube guitar amp designed for use in any situation or genre – the harder the better. The name says it all 3 – 3 – 3; three fully independent channels for three fully independent gain structures and tone stacks. Our revolutionary INFINIUM Tube Life Multiplier technology watches your tubes like a hawk, ensuring you get all the tone, all the time – and your tubes live a long and healthy life! Add to this an assignable, high-class Reverb; remote-controllable FX Loop; and switchable power amp damping, and you’ve got one awesome tone machine – the 333 INFINIUM!
The 333 INFINIUM features true Class-A/B technology with a 4 x 12AX7 front-end and 4 x 6L6 tube power stage. A masterful hand-crafted, all-tube amplifier, the 333 INFINIUM provides excellent heavy-rock tone with natural tube compression, yielding the sweet distortion and break-up you’ve come to love from the guitar icons who made rock ‘n’ roll history!
Technology years in the making, our INFINIUM Tube Life Multiplier Technology can extend the usable lifespan of your amplifier’s expensive power tubes by up to 20 times, saving you huge money and ensuring the integrity of your tone. How? This revolutionary circuit automatically and continuously monitors the performance of each output tube, and dynamically drives it towards the target operating point, for an evenly distributed load. INFINIUM also compensates for the effects of aging, automatically adjusting current levels to keep your tubes sounding as good as new – even when AC line voltages drop below nominal levels. Similar technology has been used for decades in all-wheel drive cars, where systems modulate the power going to each wheel to improve traction. Just consider the 333 INFINIUM as “4-wheel drive” for your guitar.
The 333 INFINIUM takes all the guesswork out of tube replacement by illuminating an LED next to a tube that is reaching the end of its usable lifespan. And thanks to INFINIUM’s Auto-Bias design, you simply replace the indicated tube – without a trip to the repair shop, saving you even more money.
