The 333XL-212 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. The 333XL INFINIUM takes it up a notch – 4 notches to be exact, with the addition of an overall active Presence control; a very-effective analog Noise Gate on the Lead channel; EL34 power tubes for a more compressed midrange (also compatible with a variety of output tubes); and an XL switch on the Crunch and Lead channels that adds serious bottom-end to your tone. 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 two world-class BUGERA 12″ speakers; an assignable, high-class Reverb; remote-controllable FX Loop; and switchable power amp damping, and you’ve got one awesome tone machine – the 333-212 INFINIUM!
The 333XL-212 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 333XL-212 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 333XL-212 INFINIUM as “4-wheel drive” for your guitar.
The 333XL-212 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.
