The JHS Pedals Emperor is features true analog chorus and pitch vibrato with tap tempo, waveform selection, rotary speaker simulation, true stereo output and more!

There are a lot of penguins out there but only one Emperor. Starting with the coveted vintage Arion SCH-1 chorus topology, the JHS Emperor's design and engineering expands further into new heights of what real bucket brigade tones (via a 3207 chipset) can offer. The end result allows you to have a host of vintage modulation tones at your disposal with the amenities and modern flair that only JHS Pedals can offer. From vintage Boss VB-2, CE-2, CE-1, as well as the legendary and rare SCH-1, the Emperor lets you explore true analog modulation at it's best.

Here are for Knob controls on the Emperor:  Volume, Tone, Speed, Depth.  The Volume control allows you to adjust the input by cutting or boosting the signal. This gives you the flexibility to have your tones sit back in the mix or stand out as needed. The Tone control is a variation of the original SCH-1 tone stack with several adjustments that give it a better sweep, focus and range. The Speed control allows you to adjust the time/speed of the modulation. The Tap Tempo footswitch works in conjunction with the Speed control to allow you adjust your Speed on-the-fly and in real-time.  The Depth control allows you to adjust how deep or wet the modulation is perceived.

There are two toggle switches found in the center of the unit.  The Chorus/Vibrato toggle lets you switch between Chorus mode or Vibrato mode. The Waveform selection toggle gives you three waveform options: Sine, Square, Triangle. The three waveforms provide three unique options of Chorus and also three options of Vibrato, making a total of six different modulation settings... all which can be dialed in with tap-tempo. As a starting point, both switches down is true VB-2 style pitch vibrato, both switches up is true SCH-1 chorus.

There are three 1/4" jacks on the Emperor. The Input jack receives your instrument's signal. The Output jack sends the signal out of the pedal to an amplifier or your pedal chain. You can use an optional TRS splitter cable from the Output jack and send output signal to two amps for true stereo modulation. The Tap/Expression jack allows you to connect a TRS Expression pedal or a external Tap Tempo to control the unit.   Choose which option you want to use by using an internal switch labeled "Tap/Exp."  In Expression mode, connect any TRS Expression pedal to control the pedal's speed and you will have a very natural rotary simulation effect when in Chorus mode.  The Speed parameters are perfectly preset for a very realistic rotary speaker sound with real time control at your feet.  When in Tap mode you can set the Speed of the Emperor using an external tap tempo pedal.

The Emperor can utilize true-bypass on/off switching OR buffered bypass switching.  The footswitch on the bottom left of the pedal turns the effect on/off.  Internally you will find a small dip-switch that lets you select true bypass or buffered bypass.  If you want you use the Emperor with a TRS Splitter for stereo use, you will have to use the Buffered bypass setting.  Stereo output will not function when the pedal is in true-bypass mode.  The Emperor will ship set to buffered bypass.  The buffer is a high quality buffer designed to keep the integrity and tone of your original signal in place while driving your signal so that no degradation occurs in your rig.

The Emperor runs on standard negative center 9v 100ma power.

Emperor Analog Chorus/Vibrato with Tap Tempo Guitar Effects Pedal

JHS pedals carry an unconditional "TWO YEAR" full warranty for ANY problem related to the function or operation of that pedal due to faulty parts and/or other internal problem. Simply send a copy of the receipt of purchase and JHS Pedals will honor it up to two years. JHS Pedals does not cover things such as broken knobs, pots and jacks due to abuse. JHS Pedals build them to last but not to be thrown out of an airplane. However, JHS Pedals will repair problems that are out from under their warranty like the above at a very reasonable price. Several JHS Pedals have internal trim pots which are set and sealed very carefully for the function of the circuit and it should be noted that tampering with the trim pots will void the warranty.
