JHS Effect Pedals - Twin Twelve
This JHS Twin Twelve Channel Drive Pedal brings the classic Silvertone 1484 amp's preamp and overdrive sounds to life in an all analog stompbox - very cool! It's also much more affordable than the famous "Twin Twelve" amps favored by everyone from Death Cab for Cutie to Jack White to Vampire Weekend.
The heart of the JHS Pedals Twin Twelve are the discrete transistor stages that take the place of the original tubes found in the amplifier. Each transistor stage of each pedal is meticulously hand tuned and adjusted for the perfect voltage that achieves a striking similarity to the real valve sound of the original amplifier. 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, a better dynamic range, and overall one of the best amp-like feels of any pedal JHS has made to date.
You've got four controls -Volume, Drive, Bass, and Treble. The original amp only had Volume, Bass, and Treble. The Volume acts as the master volume that the amplifier never had. By design, if the Volume control of the pedal is maxed out, the pedal is acting like a non-master volume amplifier. The Drive knob of the pedal is essentially the Volume control of the amplifier. As you turn up the Drive knob of the pedal you get more overdrive and tube-like saturation just like you would by cranking up the Volume knob on the amplifier.
The biggest difference between the Twin Twelve pedal and the original 1484 amp is that you can now crank the Drive knob of the pedal and turn the overall volume down with the pedal's Volume knob. The 1484 amplifier did not have this feature and made it, at times, tough to achieve the best cranked-up amp tones when playing small clubs. The Bass and Treble are almost exact replications of the 1484's baxandall tone circuit with only minor improvements that make them work more effectively in a guitar pedal format. If you have ever played a real 1484 amp you probably found yourself cranking up the amp's Bass control due to the fact that the first 40% of the sweep was pretty useless and completely non-audible in change. On this pedal, JHS adjusted the values within the Bass control network, giving you a more audible and useful control range. With the pedal's Bass and Treble set to noon, you have the very classic and true 1484 amp tone with plenty of room to expand and tweak. The Bass and Treble controls of the pedal are active and allow you to cut or add either frequency.
The Twin Twelve pedal can be used as an "always-on" preamp, an enhancer for your current rig, or as a powerful solo booster. The Twin Twelve also does great job at amp-like overdrive tones, treble boosting, edge of fuzz overdrive, and more.
