"There was a time when replaced transformers were [tonally] a red flag, but no more. We have replaced enough dead or incorrect replacement trannies pulled from Fender, Vox and Marshall amps with ToneClones from Mercury Magnetics to become convinced that you lose nothing, and may even improve the tone of your amp with a Mercury... our old '68 Pro Reverb sounded better with the Mercury -- stronger and more robust with a smoother and more responsive touch."

Players who know tone insist on Mercury transformers

Your quest for truly inspirational and superior tone has led you to the final link in the chain -- Mercury Magnetics. Premium guitar amplifier power transformers, output transformers and chokes.

Transformer sets are often misunderstood, yet vital musical components. They're integral to the nuances of your guitar amp's sound. Far more than tubes, speakers or other amp components, the transformers establish the platform for shaping your amp's unique sound.

Today's players are more informed and demanding than ever. They hear the differences and know that both transformer design and build-quality have a dramatic effect on their tone. Indeed, if your tube-based amp is suffering from bland and unexciting tone then it's probably related to low-end or poorly designed transformers. As amp designers, techs and manufacturers have discovered, the practice of dumping generic, low-bidder transformers into their amps doesn't cut it any more. And now you know why.

You'll be absolutely blown away by the dynamic improvement in tone only possible with Mercury upgrade transformers.

Who is Mercury Magnetics and why is our guitar amp project so important to you?

Did you know that tube-based guitar amp transformers are unusual and very different from industrial as well as audio transformers? And did you also know that it is impossible to engineer the "perfect" guitar amplifier transformer from strictly "by the book" specifications? Interestingly, almost all of the great-sounding amp transformers contain either flaws, "happy accidents," or have other issues in their construction that were not part of their original specifications.

Decades ago, when Mercury's engineers first discovered these curious phenomena, the music industry was already in the process of losing its references to tone. In the throws of converting to solid state, tube and transformer platforms were mistakenly being relegated to relics of the past. Those who knew the original technology were either retiring, dying off, or jumping ship for the "new improved" way of doing things. By the time we collectively began to realize what was happening to guitar tone, it was almost too late. "Old school" manufacturing had been all but shut down and as quality dwindled N.O.S. (new old stock) components became the last bastion of our tone.

It was during those Dark Ages that the transformer connection to tone was almost lost completely. However, Mercury was there as a hold out -- and even when it wasn't fashionable, never compromised. But as often happens, when an older era fades, the remnants of what made it great were readily available to study. And like archeologists, Mercury's engineers began sifting through the bones of the most coveted old amps in an attempt to discover what made them better, and often times so different than others.

The resulting products of those studies were the earliest ToneClone and Axiom designs. Mercury quite literally evolved a new science of guitar amp transformer design for tube-based guitar amps from there, and has continued to innovate and revolutionize it since. Perhaps few people realize the significance of these discoveries and the resultant developments. But without Mercury's catalog of transformer designs, guitar tone as we knew it would have been lost.
