FROM JACKSON AMPWORKS👇

The Jackson Ampworks Britain 4.0 is the smallest, most flexible and portable British style guitar amplifier ever made. With four distinct power settings and two blendable channels, the Britain 4.0 offers more tone and more value than any amp ever made.

If you are looking for one amp that will cover all the classic British guitar tones of the last 50 years along with a host of new tones never before available then the Britain 4.0 is your amp.

SMALL SIZE, HUGE TONE, TREMENDOUS VALUE

Jackson Ampworks, the creator of “The Britain” amplifier, has just released The Britain 4.0.

With careful consideration of the feedback from users of the original Britain and the Britain 2.0, Jackson Ampworks has totally redesigned the amp to become the most pristine, versatile, and compact boutique amp on the market today. The new Britain 4.0 is 18 pounds lighter than its original predecessor, 8” more narrow and 3 times more powerful! In addition to these changes they added a second channel to the amplifier, a unique footswitch-able boost circuit for the Britain’s now legendary EF86 channel, series effects loops for each channel, and selectable 15/25/30W Class A or 50W Class A/B operation that features 2 different sets of output tubes for unmatched versatility.

TWO CHANNELS - INFINITE TONES

The Britain 4.0 features two totally separate channels, each with its own set of dedicated tone controls. While two channel amps have been available for any years, the magic of the Britain lies in its ability to blend those two channels together to create an infinite number of tonal options.

Channel 1 is the exact same EF86 based preamp that was featured in the original Britain but has been updated with Jackson Ampworks own footswitch-able boost circuit that true bypasses the Treble and Bass controls resulting in a substantial boost in volume, gain and tonal purity. Channel 1, being the higher gain of the two, is considered the dirty channel of the amp and offers a very broad frequency response that works to deliver your instruments true voice with minimal coloring or artifacts.

Channel 2 of the Britain 4.0 is a 12AX7 based “Top-Boost” preamp that balances perfectly against Channel 1 by providing pristine clean tones incredible headroom and articulation. This channel, which was designed to remain clean longer than Channel 1, embodies the very definition of clean British guitar tone but is enhanced with increased richness and depth.

Channels 1 and 2 are internally linked so that the use of the input labeled “1/2” sends the guitars signal to both channels equally. In this arrangement, each channel is active along with its associated tone controls and blending of the two channels is a simple as adjusting the Volume control for each channel. The true advantage of this type of arrangement lies in the ability to blend Channels 1 and 2 together while still allowing tonal shaping of each channel via their respective Treble and Bass controls.

Plugging into the input labeled “2” breaks the internal connection to Channels 1 and 2 thereby allowing them to function independently. This feature allows the musician to use a completely different signal chain (floor based effects etc.) for each channel if desired, and is fully expanded by the use of an ABY box to select channels 1, 2 or both.

With all of these tonal options available, the Britain 4.0 truly delivers Two Channels, Infinite Tones.
