The gain structure and tonal character of the 6262/6262-212 are built on the same fundamentals as the 6260 - but more midrange, making them perfect for 80's rock and metal. You also get fully independent control of EQ, Presence and Reverb on both channels. Ultimate Tone Mastery. A lot of amp manufacturers call their Treble/Mid/Bass knobs "tone" controls. We call ours EQ because we spent a lot of time making sure that they each have a unique character. Treble really screams; Mid puts you about six rows into the audience; Low can add more growl than an angry Kodiak bear. The Presence control is tailored to smooth out your tone or add enough bite to cut through any cymbal. It can bring new life to darker sounding instruments. Infinium Valve Life Multiplier Technology Our revolutionary Infinium Valve Life Multiplier technology is like having your very own technician inside your amp constantly monitoring and tweaking valve 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 valves sounding as good as the day they were installed. If and when a valve does reach the end of its life, the system even tells you which one to replace. All you need do is replace the faulty valve and let Infinium take care of the rest for you. This all adds up to more consistent sound quality and longer life for your valves. Maintenance for valve amps has never been this easy!
