Blast off to a whole new universe of sounds with the Electro-Harmonix HOG, a polyphonic guitar synthesizer with NO special pickup required. It gives you complete control of up to 10 interval pitches including fifth and third intervals, glistening filter sweeps, and insane pitch bends. Dedicated filtering and envelope control, with numerous setup options, make the HOG a must-have performance instrument.The HOG can simultaneously generate multiple octaves and harmonics from your input signal. Whether you play single notes, arpeggios or full chords, the HOG will track every note you play. In addition, the HOG has seven expression modes that enable you to modify your sounds using the included expression pedal, a MIDI controller, or the expression button on the HOG itself. There is also an amplitude envelope and a 2nd order low-pass filter with resonance. The optional EH footcontroller (Item #153342) allows you to store and load six presets.You have control over the HOG's basic audio circuitry with an input gain slider (with clip LED), a dry output slider, and a bypass switch. Audio I/O includes 1/4" Hi-Z input, 1/4" output, and a buffered direct output jack. The voice controls let you access the polyphonic synthesizer section. There are 10 voice sliders on the HOG, each with a white cap with a black line that controls the output volume for its voice. The ten sliders let you generate notes two octaves down, one octave down, the incoming signal, a fifth up, one octave up, an octave up plus a fifth, two octaves up, two octaves up plus a third, three octaves up, and four octaves up. The selectable envelope section controls the amplitude attack or decay of the voices, with separate sliders for the lower five voices and upper five voices.The Spectral Gate button activates circuitry that emphasizes the loudest frequency or harmonic and reduces the volumes of all other present frequencies and harmonics. The filter frequency slider controls the cutoff or peak frequency of the low pass filter, while the filter resonance slider controls the Q or peak of the filter.The HOG's seven different expression modes are selected consecutively by the expression mode switch: bend one octave, bend one step, volume, freeze plus gliss, freeze plus volume, wah-wah, and a filter. There is also an expression reverse mode and you can control the expression modes externally with an expression pedal or modulate any of the expression modes using MIDI pitch bend.. ...details  Electro-Harmonix Guitars > Guitar Amplifiers and Effects > Guitar Effects > Guitar Effects Pedals > Modulation, Chorus, Flanging, Phasing and Tremolo > Electro-Harmonix XO Stereo Clone Theory Analog Chorus / Vibrato Guitar Effects Pedal.

The Electro-Harmonix Germanium 4 Big Muff Pi overdrive and distortiuon pedal is a classic 1960's overdrive based around a hand-selected germanium transistor. To get the best results from the E-H Germanium 4, just set aside some time to practice in a quiet room—just you, your amp, and the Germaium OD. The interaction of each control will reward you with many different flavors of exceptional vintage overdrive.In addition to a Gain control, the Electro-Harmonix Germanium 4 overdrive lets you control Bias for attack and the circuit volts for that sweet spot found when a battery's voltage dips. The Gain control adjusts the amount of input signal that is fed to the Electro-Harmonix Germanium 4. The more the knob is rotated the harder the germanium transistor and drive components are hit. The Bias control adjusts the current gain that is sent to the Germanium transistor. It works together with the Voltage control to attain the over all tone. The bias control works specifically with the Germanium transistor. The Volts knob controls the amount of voltage that is applied to the Germanium OD. Set at full, 9V is applied. When set at minimum, 3V is applied. By limiting the voltage a number of interesting saturations can be set up for variations in tone. A footswitch turns true bypass on or off.The Electro-Harmonix Germanium 4 runs off of a 9V battery or you can connect a 9VDC adapter capable of delivering at least 100mA to the 9V power jack. The optional 9V power supply from Electro-Harmonix is 9.6DC-200BI (same as used by Boss and Ibanez) 9.6 Volts DC 200mA. The AC power adapter must have a barrel connector with center negative.

Some possible samples and settings you can create with the EHX Ring Thing: Vibe-A-Tone: a control setting that produces a chorus/tremolo/vibrato effect Baritone guitar: thanks to pristine polyphonic pitch shifting, you can transform a standard tuned guitar into a baritone guitar or a 6-string bass Drop tuning with distortion: dropping a regularly tuned guitar down to B with the EHX Ring Thing and adding a distortion pedal afterwards produces a huge sound Tremolo bar effects: adding an expression foot pedal to the Electro-Harmonix Ring Thing produces classic dive-bomb effects using any electric guitar The Ring Thing guitar pedal set for two octaves above with an expression foot pedal produces contemporary pitch pedal effects Tunable moving harmony: pressing the tune switch while holding a not automatically tunes the Ring Thing to your guitar Ring modulator you can play musically: all parameters including the tuning can be stored in presets. ...details  Electro-Harmonix Guitars > Guitar Amplifiers and Effects > Guitar Effects > Guitar Effects Pedals > Delay and Reverb > Electro-Harmonix Classics Holier Grail Reverb Guitar Effects Pedal ¹. The Holier Grail effects pedal expands on the capabilities of the Holy Grail pedal from Electro-Harmonix. It contains 8 different reverb presets: SPRING, HALL, ROOM, and FLERB each at a LONG and SHORT reverb length. In addition to reverb, there is a GATE that ends the reverb tail early for an unnatural yet often pleasing reverb sound.Holier Grail Controls: TYPE Switch—Selects the type of reverb sound that the Holier Grail will produce: SPRING, HALL, FLERB or ROOM. LENGTH Switch—Selects between a LONG or SHORT reverb length. A LONG reverb length is attributed to making a bigger sound, such as a large hall, room, or reverb tank. A SHORT reverb length will yield a smaller sound, such as a small room, hall, or reverb tank. BLEND Knob—Is a Wet/Dry control for the reverb signal. As you turn the BLEND knob clockwise you will hear more reverb and less of your instrument. The Holier Grail is designed so that as you turn the BLEND knob from its minimum position to the 12 o'clock position you will hear a subtle amount of reverb added to the output. As you turn the BLEND knob from 12 o'clock to its maximum position the amount of reverb you hear will increase dramatically. It is designed this way so musicians can hone in on just the right amount of subtle reverb. GATE Switch—The GATE switch determines how the gate circuit will affect the audio path. The 3 positions are OFF, REVERB ONLY, and REVERB + DIRECT. When the GATE switch is in the OFF position, the gate is completely bypassed and the gate has no effect on the audio path. In the REVERB ONLY position, the output of the reverb generator will be fed into the gate before it goes to the BLEND knob. The output of the gate will then go to the wet side of the BLEND knob to mix with the dry signal. In the REVERB + DIRECT position, the signal after the BLEND knob goes into the gate so that both the wet and dry signals are gated. The output of the gate is then sent to the MAIN OUTPUT of the Holier Grail. In this last position, it is possible to gate only the dry signal by turning the BLEND knob to its counter-clockwise (minimum) position. GATE THRESHOLD Knob—This knob determines when the gate should actually be opened or closed. When the GATE THRESHOLD knob is in the counter-clockwise (minimum) position, the threshold is set to high; it will take a very loud signal to open the gate. When the GATE THRESHOLD knob is in the clockwise (maximum) position, the threshold is set to low; the gate will only need a small signal to open up. GATE REVERSE Switch—This slide switch enables you to reverse the normal operation of the gate. When the GATE REVERSE switch is off (left position), the gate will act normally; the gate is open when the signal is above the gate threshold and the gate is closed when the signal is below the threshold. When the GATE REVERSE switch is on (right position), the gate will act opposite to how it normally works; the gate is closed when the signal is above. ...details  Electro-Harmonix Guitars > Guitar Amplifiers and Effects > Guitar Effects > Guitar Effects Pedals > Harmonizer, Pitch Shifter, Octave and Ring Modulator > Electro-Harmonix Frequency Analyzer XO Guitar Effects Pedal.

The effect pedal's feedback control increases the number of delay repeats or multiple echoes. At high settings the unit will begin to self-oscillate. Fairly high feedback with short delay settings produces a reverb type of effect. The Mod switch will enable a slow modulation on the delay time similar to the chorus modulation of the Deluxe Memory Man. The Status LED shows that the Electro-Harmonix Memory Toy is in effect mode. When the LED is off, the Memory Toy is in true bypass mode.

Flip on the bright switch to add some bite and definition.The volume knob controls the volume or loudness of the amplifier. As you turn the Volume knob clockwise, the 22 Caliber's output gets louder. At a certain point in the knob's travel, the output will start to overdrive. At this point, you are beginning to exceed 22 Watts on your loudest notes. Turning the volume knob further clockwise will produce a more overdriven sound from pure power amp saturation. When engaged, the power amp's bright switch adds a subtle high-end boost presence to your output signal. When in the normal position it is defeated yielding a signal that passes from input to output uncolored. Plug the output of your guitar, effects pedals, or any other instrument into the input jack using a standard 1/4" instrument cable. Connect the 22 Caliber's output jack directly into almost any speaker cabinet. Use a speaker cable between the Electro-Harmonix 22 Caliber and speaker cabinet as you would with any power amplifier, though you can get away with using an instrument cable if absolutely necessary.

The pedal features the exact same warm analog circuit, with premium, vintage, integrated circuits, all housed in a more pedalboard-friendly enclosure.The Blend control allows you to vary the mix of direct and delayed signals, and the center-position setting equals out both levels. Feedback provides delay repeats, or multiple echoes. Fairly high feedback with short delay settings produces a reverb effect. The Delay control determines the time between direct and delayed signals, and between the repeats when feedback is used. Strange, eerie, and unusual pitch-shift effects can be produced by changing the delay, while playing—especially while using feedback. The Chorus/Vibrato control introduces a modulation in the delay time: slow for chorus, faster for vibrato. This produces a "Doppler" pitch shifting in the delayed signal. A rich, vibrant chorus effect is produced with the switch set to chorus, delay fairly short, blend at the center, chorus set high, and feedback fairly high.. ...details  Electro-Harmonix Guitars > Guitar Amplifiers and Effects > Guitar Effects > Guitar Effects Pedals > Harmonizer, Pitch Shifter, Octave and Ring Modulator > Electro-Harmonix POG2 Polyphonic Octave Generator Guitar Effects Pedal.
