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.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch3\u003eTWO CHANNELS - INFINITE TONES\u003c\/h3\u003e\r\n\r\n\u003cp\u003eThe 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eChannel 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eChannel 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eChannels 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003ePlugging 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWith all of these tonal options available, the Britain 4.0 truly delivers Two Channels, Infinite Tones.\u003c\/p\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\r\n\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch3\u003eCONSTRUCTION FEATURES\u003c\/h3\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003ePrecision Cut and Welded Anodized Aluminum Chassis    Silver Plated Teflon Hookup Wire and Shielded Cable\u003c\/li\u003e\r\n\u003cli\u003eChassis Mount Ceramic Tube Sockets    4” High Flow Output Tube Cooling Fan\u003c\/li\u003e\r\n\u003cli\u003eProprietary Vented Cabinet Design Custom Designed Fan Isolation Mount\u003c\/li\u003e\r\n\u003cli\u003eLaser Engraved Stainless Steel Front and Back Face Plates Precision Cut and Drilled 1\/8” Fiberglass Turret Boards\u003c\/li\u003e\r\n\u003cli\u003eCustom Wound Output and Power Transformers    Heavy Duty Carling Switches\u003c\/li\u003e\r\n\u003cli\u003eF\u0026amp;T Filter Caps   1W 5% Carbon Comp and Carbon Film Resistors\u003c\/li\u003e\r\n\u003cli\u003eMallory 150 Coupling Capacitors   Tube Shields for all preamp tubes\u003c\/li\u003e\r\n\u003cli\u003eCentral Point Grounding with Star Ground  Genuine Neutrik Jacks for Input, FX Loop and Speaker Connections\u003c\/li\u003e\r\n\u003cli\u003eDistributed Power Supply  Die-cast Chrome Plated Emblem\u003c\/li\u003e\r\n\u003cli\u003eFully Regulated DC Heater Supply for All Preamp Tubes Internally Shielded Cabinet\u003c\/li\u003e\r\n\u003cli\u003eFully Isolated Input, FX Loop and Speaker Jacks   Threaded Metal Inserts used to attach back panel of cabinet\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch3\u003eSPECIFICATIONS\u003c\/h3\u003e\r\n\r\n\u003cp\u003eOutput Power\u003c\/p\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003e15W Class A – (2) – EL84  Cathode Bias    Low Voltage\u003c\/li\u003e\r\n\u003cli\u003e30W Class A – (4) – EL84  Cathode Bias    Low Voltage\u003c\/li\u003e\r\n\u003cli\u003e25W Class A – (2) – EL34  Cathode Bias    Low Voltage\u003c\/li\u003e\r\n\u003cli\u003e50W Class A\/B – (2) – EL34    Fixed Bias  High Voltage\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eTubes\u003c\/p\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003ePreamp    Channel 1   1x EF86\u003c\/li\u003e\r\n\u003cli\u003ePreamp    Channel 2   1x 12AX7\u003c\/li\u003e\r\n\u003cli\u003ePhase Inverter        1x 12AX7\u003c\/li\u003e\r\n\u003cli\u003eOutput        2x – EL34; 4x – EL84\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eRectifier: Solid State; 5U4G Simulated in 15\/30W and 25W Mode\u003c\/p\u003e\r\n\r\n\u003cp\u003eInput Impedance: 1MΩ\u003c\/p\u003e\r\n\r\n\u003cp\u003eFX Loop Impedance: 1MΩ\u003c\/p\u003e\r\n\r\n\u003cp\u003eFX Loop Wiring: Stereo Plug Tip Send\/Ring Return\u003c\/p\u003e\r\n\r\n\u003cp\u003eWeight: 31lbs (Boxed)\u003c\/p\u003e\r\n\r\n\u003cp\u003eSize\u003c\/p\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003eHead Size: 14″ x 8.5″ x 8.25″\u003c\/li\u003e\r\n\u003cli\u003eHead Size (Boxed): 18″ x 13″ x 12″\u003c\/li\u003e\r\n\u003cli\u003e1×12 Combo Size: 21.5″ x 18.5″ x 11.5″\u003c\/li\u003e\r\n\u003cli\u003eShipping Package Size:    20″ Wide  12″ Tall  12″ Deep\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003eLine Voltage: 120VAC or 240VAC; Switchable via Back Panel\u003c\/p\u003e","brand":"Jackson Ampworks","offers":[{"title":"Default Title","offer_id":44449728823399,"sku":"47484","price":2895.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/jackson_ampworks_britain_4_head_black_black_main_794917af-bb06-418d-868d-ac58cc734471.jpg?v=1787090163","url":"https:\/\/vintageking.mom\/products\/jackson-ampworks-britain-4-0-head-black-black","provider":"Vintage King","version":"1.0","type":"link"}
