In 1963, Silvertone* introduced the 60 Watt Model 1484 guitar amplifier. Originally a student model amplifier, the 1484 has since become legendary, hard to find, and coveted by some of the biggest names in music. From the time of its debut in the Sears Catalogue until its discontinuation only four years later in 1967, the model 1484 "Twin Twelve" amplifier is considered a Van Gogh of sorts, as it developed a great appreciation and worth years after being discontinued.

Artists such as Beck, Death Cab for Cutie, The White Stripes/Jack White, and, more recently, Vampire Weekend and Coldplay have brought this rare amp to the forefront of popular music. The JHS Pedals "Twin Twelve" channel drive is the first ever all-analogue stomp box that replicates the classic preamp/overdrive tones only found in the Silvertone 1484 "Twin Twelve" amplifier.

This pedal requires standard 9V DC Negative power, consumes less than 100mA, and measures 2.2"x4.3"x1.5

The heart of the JHS Pedals Twin Twelve is the discrete transistor stages that replace the original tubes found in the amplifier. Each transistor stage of each pedal is meticulously hand-tuned and adjusted for the perfect voltage that is strikingly similar to the original amplifier's real valve sound.

To help achieve the weight and power of the original valve design, the circuit is designed around a charge pump that internally converts your standard 9V DC Negative power up to a powerful 18 volts. This conversion gives you more punch, better dynamic range, and overall,l one of the best amp-like feels of any pedal we have ever offered.
