Jackson Audio Twin Twelve Silvertone 1484 Preamplifer

Jackson Audio Twin Twelve Silvertone 1484 Preamplifier

The Jackson Audio Twin Twelve recreates history. In 1963 Silvertone released the iconic Twin Twelve Amplifier.

Originally listed in the sears catalog as 1484, the Twin Twelve was offered from 1963 to 1967 and became the most coveted of all the Silvertone amplifiers.

The unique sound of this amplifier proudly powers the tones of many of today’s best rock icons. These are guitarists such as Jack White, Dave Grohl, Beck, Billie Joe Armstrong (Green Day), Dan Auerbach (The Black Keys), and many more.

Today Jackson Audio and Silvertone make history again with the introduction of the 1484 Twin Twelve Pedal.

An exact recreation of the legendary Twin Twelve amplifier, the 1484 Twin Twelve Pedal is a studio-grade preamp, booster, EQ or overdrive depending on how the controls are set.

Bring back the classic Silvertone clean and overdriven tones and own the tone of legends.

Relive history with the 1484 Twin Twelve Pedal.

Main Features:

• Preamp / Overdrive pedal
• Exact recreation preamp section of the 1960s Silvertone 1484 Twin Twelve amplifier
• Designed closely with Silvertone
• Accurately recreates the unique amp sound popularized by many of today’s rock icons
• Use as a preamp, booster, EQ or overdrive
• Authentic vintage looks paired with top-mounted jacks – for ease of pedalboard mounting
• Powered by (opt.) 9 V DC PSU (centre -, 2.1mm, ~ 35 mA current draw)

This is what Jackson Audio has to say:

“The 1484 Twin Twelve Pedal is a part-for-part recreation of the Silvertone Twin Twelve Amplifier.

Not inspired by, or modeled after the original, the 1484 Twin Twelve Pedal takes the exact schematic from the legendary amplifier. However, it replaces all of the vacuum tubes with JFETs. JFETs are a unique type of transistor that behave very much like vacuum tubes.

These features of JFETs are what give the 1484 Twin Twelve Pedal the same touch sensitivity and dynamic response as the original amplifier.

To gain every bit of performance and tone out of the JFETs, we built a robust power supply. This includes a voltage doubler, which internally converts 9V to 18V so the JFET’s have a much greater dynamic response. Also, it improves touch sensitivity when compared to pedals running at 9V.

The Twin Twelve is hand-built, using top-quality parts. It has a polished stainless steel enclosure just like the original amplifier chassis. Perhaps the most iconic visual element of the Silvertone 1484 Amplifier are the knobs. We custom-made them to recreate the classic look.

We looked at this in detail in bringing this legendary circuit back in its original form, but we didn’t stop there. To offer features that players need in this era, we included a soft-click true bypass foot switch. This means your bypassed tone remains intact and the loud pop of switching is a thing of the past.”

Controls

How Do the Volume and Gain Controls Interact on the Jackson Audio Twin Twelve Pedal?

The Twin Twelve Pedal offers a dynamic interplay between its volume and gain controls. This interaction makes it easy to shape your tone.

• Volume Control: Adjusting the volume control not only sets your overall output but also influences how your sound hits the amplifier. For a cleaner tone with subtle edge, keep the gain lower while pushing the volume up.
• Gain Control: Increasing the gain introduces that classic tube-like saturation and warmth. As the gain is turned up, the pedal produces richer, more vintage breakup.

The true magic happens when gain and volume interact. Tweak these controls together and get anything from a smooth, clean boost to a gritty, overdriven sound.

There are also treble and bass controls which are self explanatory!

Recreating the Iconic Sound of the Original 1484 Twin Twelve pedal

The Twin Twelve Pedal is more than just a nod to the past—it’s a faithful recreation that brings the legendary Silvertone amplifier tones back to life. But how exactly does this pedal achieve that classic sound?

Multi-functional Design

The 1484 functions as a preamp, booster, EQ, or overdrive giving you the flexibility to fine-tune your sound to closely match the original amplifier’s character. Whether you’re seeking the pristine cleans or the grittier overdriven tones, the Twin Twelve pedal delivers.

Precision Engineering

Recreating the vintage tones involves meticulous engineering. This pedal has been crafted to mirror the circuitry and tonal characteristics of the original amplifier. Such precision ensures that every nuance, from the subtle warmth of the clean settings to the raw edge of the overdrive, is captured and can be reproduced consistently.

Control Flexibility

The pedal’s design affords extensive control over its many features, enabling you to sculpt your desired tone with precision. Adjust the controls judiciously to experience the dynamic range of tones—truly reflective of the iconic sounds from bygone days.

A Journey Through Time

By embracing cutting-edge technology to replicate classic components, the 1484 Twin Twelve Pedal gives you a chance of owning a piece of the past – but smaller!
