1990 INFINIUM
You asked... We listened... Then we listened some more. Then we gave the 1990 INFINIUM an even cooler look – with flawless performance and better sound than ever! The INFINIUM version of our highly-popular 1990 amp head allow you to switch between full-throttle pentode, or more harmonic triode (60-Watt) operating modes.

We gave the Clean and Lead channels individual Master volume and Reverb controls. We even added a dual-control footswitch that our competitors often charge extra for. Then we used our powerful economies of scale and advanced manufacturing practices, to produce a superb value that puts Biting British Tone within the reach of anyone who has ever lusted for it!

Classic All-Tube Design
The 1990 INFINIUM features true Class-A technology with a 3 x ECC83 front-end and a 4 x 5881 tube power stage. A masterfully crafted all-tube amplifier, the 1990 INFINIUM provides excellent ‘90s-style rock tone and natural tube compression, resulting in the outrageous distortion and break-up that launched America’s grunge revolution.

The hand-selected ECC83 preamp tubes in 1990 INFINIUM’s ‘90s-era preamp provide a raucous metal tone, for everything from sweetly-purring blues to mind-blowing crunch. The mighty 5881 power tube is typically used in high-end guitar amplifiers because of its greater distortion characteristic at lower output levels than other power tubes – and the 1990 INFINIUM harnesses every last drop of that power to awesome effect.

INFINIUM Tube Life Multiplier Technology
Our revolutionary INFINIUM Tube Life Multiplier technology is like having your very own technician inside your amp constantly monitoring and tweaking tube performance for the ultimate in tonal integrity and reliability. This revolutionary circuit not only optimizes the performance of each output tube, it dynamically balances the drive between them to more evenly distribute the load. With INFINIUM, your tubes last up to 20 times longer, saving you substantial money over the lifespan of your amplifier. INFINIUM also compensates for the effects of aging, automatically adjusting current levels to keep your tubes sounding as good as the day they were installed.

If and when a tube does reach the end of its life, the system even tells you which one to replace. All you need do is replace the faulty tube and let INFINIUM take care of the rest for you. This all adds up to more consistent sound quality and longer life for your tubes. Maintenance for tube amps has never been this easy!
