In order to offer so many color options without long lead times, we have partnered with Jackson Ampworks in a unique and exciting way.

In anticipation of your order Jackson has already built and bench tested chassis for each of their models and have them at their shop in Keller, Texas. They have constructed the cabinet enclosures, however have they don't cover the enclosures until your order is placed. The moment we receive an order from you we will pass along the details to Jackson Ampworks and they'll cover your amp in the color of your choice and ship directly to you! This normally takes about 2 days. We're excited about this partnership! Not only does this offer you the opportunity to choose color options, but it guarantees that you're receiving the most factory fresh amp possible!

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 our 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.

So Versatile It’s Like Having four amps in one!
The Britain 4.0 is the only amp anywhere that offers switch-able power output of either 50W Class A/B using EL34’s, 25W Class A using EL34’s or 15/30W Class A using EL84’s. This adjustable power feature allows the player to tailor the amps response and tone to any given musical setting. In high volume situations, select the 50W mode for maximum volume and clean headroom. When less volume is desired, select the 25W or 15/30W mode and enjoy the early breakup and harmonic richness that only comes from low power Class A operation. The inclusion of the 15/30W Class A power modes using EL84’s extends the tonal range of the Britain 4.0 by lowering the amount of headroom even further and allows for overdriven tones at a lower volume along with the characteristic chime and sparkle that is inherent in EL84’s. When in 25W and 15/30W Class A modes, the Britain 4.0 is cathode biased and features a proprietary circuit that exactly reproduces the natural compression and sustain of a 5U4G tube rectifier. These features give the Class A modes their own unique voice and a softer, more spongy attack. In 50W Class A/B EL34 mode, the Britain 4.0 switches to high voltage operation and is fixed biased. The combination of high voltage and fixed bias allows the Britain 4.0 to have a very quick and aggressive attack with increased headroom and volume.

Each of the 4 power modes have been developed to add versatility and character to the tone while giving the player the ability to carry one small amp that will work in any musical setting.
