Thank you for choosing the Imperial MK II guitar amplifier. The Imperial was the very
first production model built by Tone King. It was introduced in 1993, and has been a
favorite of guitarists for over 20 years now. The MK II update incorporates all that I’ve
learned as an amp designer over these past 20 years, without changing the essential
character of the amp. If anything, the MK II digs deeper for an even more authentically
vintage sound and feel.
I designed the Imperial back in 1990-1993. At the
time, I was inspired by listening to vintage amps such
as the Fender Deluxe Reverb and the Fender Tweed
Deluxe. It was clear that the authentic vintage amps
had a certain mojo that was missing in modern amps.
They had a certain feel that made you want to play
them – a compliant, broken-in feel. They also had a
certain transparency to their tone, a harmonic
complexity, and an expressive quality that I couldn’t
find in new amps at the time. My goal was to build a
new amp that could capture that that vintage magic.
Being an Electrical Engineer, I was able to absorb a lot
of the electronic necessities of such as design fairly readily, but I hit a stopping point
when it came to the cabinet design. After prototyping electronic designs using a fine
sounding vintage speaker cabinet, I became quite aware of the important role the
cabinet can play once I built my first speaker cabinet, to disappointing results. After
years of building test cabinets, experimenting with wood types, construction methods,
and many other factors, I began to develop a sense for how to control the voicing of a
cabinet to achieve the sound and feel I was after. The Imperial was the first of my
designs to benefit from these efforts in cabinet design, and I like to think that this is
why it is such a special amp that has been so successful for all these years.
Still, being primarily an experimenter, I never
stopped trying to learn new ways to improve my
designs. This new MK II design incorporates
development work I’ve done over the past 20
years and represents the best of what I can do at
this time.
To be specific, the MK II is built using a layout
scheme I’m calling “handwired board”, which I
believe to be an ideal construction method to extract the best tone from any circuit
design. It has great advantages in terms of component placement, wiring length, and
wire routing, and has a real, tangible effect on the sound and feel of an amp.
In addition, the MK II includes the new Ironman/II attenuator, which I feel is a great
advance in that it provides fletcher-munson volume compensation to correct for the
way the ear perceives sound at low volume, as well a circuitry that compensates for the
way the speaker operates at low volume, to preserve the experience of playing a
cranked amp at low volume better than had been done before.
I thank you for your purchase of this special version of the Imperial, and I hope you
enjoy playing it as much as I do.
