Up for sale, a Jackson Ampworks Britain 30 tube amp head and matching 1x12 cabinet, loaded with a Celestion Gold speaker. Jackson Ampworks is a small boutique amplifier shop located just north of Fort Worth, TX, using only the highest quality parts and processes with their small-batch productions.
The Britain 30 is a two-channel design, and each channel has a distinctly voiced Vox-esque flavor. Channel 1 is centered around an EF86 tube and is the higher gain of the two channels, offering bright, harmonically-rich JMI-era drive and sonic complexity. A footswitchable boost bypasses this channel's EQ for additional gain and a substantial jump in overall volume. Channel 2 uses a 12AX7 in the preamp, delivering more overall headroom, while still yielding plenty of sizzling overdrive at higher volumes or when utilizing the amp's power scaling options. The global Power knob dictates the voltage the EL84 power tube quad sees, capable of a full 30 watts or as low as 1/8 of a watt. Much more effective than a Master Volume, the Power control retains the amp's gain characteristics at both stage and bedroom-friendly volumes.
Channels 1 and 2 are internally linked, and the input labeled "1/2" sends the instrument's signal to both channels equally. In this arrangement, both channels can be blended, and their Volumes and EQ controls are interactive. Plugging into input 2 breaks the internal connection between the channels, allowing them to operate independently. This input is designed for use with an ABY box if desired (not included), allowing the player to independently select each channel.
The ported 1x12 cabinet is loaded with a Celestion Gold alnico magnet speaker, delivering ample low end, pristine trebles, and a rich, resonant response.
The Jackson Ampworks Britain 30 features Mallory 150 capacitors, carbon film resistors, genuine carling switches, cathode bias, custom wound overspec power and output transformers, hand-wired construction, genuine neutrik jacks, an anodized aluminum chassis with laser engraved stainless steel panels, and a 13-ply dovetail-jointed Baltic Birch cabinet.
Cosmetically, this amp is near-mint, with red and cream two-tone tolex, silver piping, and silver sparkle grillcloth.
