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
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-biddertransformers 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 totone. 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
The resulting products of those studies were the earliest ToneClone and Axiom designs. Mercury quite literally evolved a new
science of guitar amptransformer 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

explains Mercury's brands and
We build transformers exclusively for guitar
amplifiers. And we're unique in a number of related ways:
100% American made -- no hidden imports -- we really do make 'em
from scratch, right here in California!
100% handmade and hand-tuned using only handwound
components. We never compromise or play bean-counter games by
short-cutting, attrition or using cheaper materials. Each and every transformer is consistent. If you ever need
to replace one of our transformers, your amp won't lose its tone-- your replacement will
sound exactly the same as the
American-made steel -- we're the only transformer manufacturer who custom orders,
from an American steel mill, the unique alloys used in our transformers. These
alloys are not only made here in the USA to military specifications,
they are not available anywhere else in the
world. They're the same alloys used in the all-time best-sounding transformers during the "sweet spot" era
(pre-1965) of guitar amplification history.
Things are never stagnant around here. Mercury maintains active and ongoing R&D (research &
development). All kinds of new and exciting-sounding transformerdesigns
(Axiom series), as well
as our ongoing cloning of outstanding transformers mined from the great old amps
(ToneClone series). For vintage British amp freaks, check out our Radiospares, Hiwatt and Partridge series. And many
modern amps can be upgraded with our APS series -- our
newest line of guitar amp-specific transformers.
For any popular amp design we're likely to have not just one but several transformers for different purposes and
characteristics. It's always a smart idea to discuss
replacement, restoration or upgrading with your Mercury rep. -- you'll find his input
Our transformers are found in the amps of
virtually every major player in the world. Many specify Mercury and won't play an amp without
Mercury transformers are standard components or
factory upgrades available in virtually all high-end boutique amps,
boutique and custom shop lines.
Mercury transformers are so highly rated that they
typically increase the value of any amplifier they're installed
