Distortion & Gain – Electro-Harmonix

Lizard King

Electro Harmonix — Tue, 28 May 2024 16:06:10 +0000

POWER JACK

An optional 9VDC, center-negative power supply can be connected to the power jack to provide power without a battery. The Lizard King requires 8mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack.

VOLUME KNOB

Sets the output level of the Lizard King.

OCTAVE KNOB

Controls the intensity of the octave effect. Turn clockwise for more octave, or turn counterclockwise for a deeper sound.

SUN/SHADOW SWITCH

Enhances the octave fuzz and clean tones of the Lizard King. With this switch set to SUN, the octave fuzz is boosted with a more driving midrange, and the clean tone accessed by the BLEND knob has more treble and bass frequencies. When the switch is set to SHADOW, the clean tone is unchanged, and fuzz tone is tighter.

BLEND KNOB

Blends between the fuzz/octave and a clean signal with no fuzz. This is useful for maintaining the attack and low-end for bass instruments, and for allowing more harmonic detail for guitar or other chord instruments. When Blend is set fully counterclockwise, the output is a clean tone. As the knob is turned clockwise, more fuzz tone is mixed in. When Blend is set fully clockwise, the output is all octave fuzz effect.

TONE KNOB

Controls the high frequencies of the Lizard King. When the knob is fully clockwise the pedal is “wide open” – passing the full fuzz tone. As this knob is turned counterclockwise, high frequencies are rolled off.

INPUT JACK

Audio input to the Lizard King.

AMP JACK

Audio output from the Lizard King. In bypass mode, the AMP jack is directly connected to the INPUT jack.

FOOTSWITCH & STATUS LED

The footswitch engages or bypasses the effect. The status LED lights when the effect is engaged. The LED is off in bypass mode. The Lizard King employs True Bypass.

LPB-3

Electro Harmonix — Mon, 06 May 2024 20:15:03 +0000

POWER JACK

Insert the output plug of the supplied AC Adapter into the power jack. The LPB-3 requires 120mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack. The LPB-3 does not take batteries.

MAX SWITCH

Boosts the gain at the output stage, and sets the maximum gain of the LPB-3—from Input to Output—to either 33dB or 20dB. Set MAX to 20dB for greater dynamics; set MAX to 33dB to drive the signal harder and potentially send your amp into saturation along with higher BOOST knob settings.

Q SWITCH

Sets the resonance or bandwidth of the MID EQ. Q set to LOW mode yields an EQ that sounds broader or rounder and affects a larger range of frequencies. In HIGH mode, the EQ sounds sharper or peakier, affecting a narrow range of frequencies.

BOOST KNOB

Sets the output level of the LPB-3, basically working like a volume control.

MID LVL KNOB

Boosts or cuts the MID EQ. Turn the MID LVL knob clockwise from its noon position to boost the MID EQ frequency. Turn MID LVL counterclockwise to cut MID EQ. Set MID LVL to its center position for a flat MID EQ response.

TREBLE KNOB

Boosts or cuts frequencies above 3.25kHz. Turn the TREBLE knob clockwise from noon to boost the high end. Turn the knob counterclockwise to cut highs. Set TREBLE to its center position for a flat treble response.

PRE-GAIN KNOB

Adjusts input gain from 0dB (unity) to 20dB before the signal hits the EQ circuitry. Use PRE-GAIN in conjunction with BOOST and MAX to fine-tune the total volume and gain through the LPB-3. Pro tip: If the EQ knobs are set in the boost half of their range, signal clipping can be avoided by decreasing PRE-GAIN. If the EQ settings are set to cut, turn up PRE-GAIN for more volume.

MID FREQ KNOB

Adjusts the MID EQ center frequency, which is boosted or cut by the MID LVL knob. The frequency range of this knob is 240Hz to 3.3kHz. Pro tip: For a brighter sound, try cutting the low MIDs by setting MID FREQ to 10 o’clock and MID LVL to 11 o’clock.

BASS KNOB

Boosts or cuts frequencies below 240Hz. Turn BASS clockwise from the noon position to boost the low end. Turn the knob counterclockwise to cut. Leave BASS in its center position for a flat bass response.

INPUT JACK

Audio input jack. Input impedance 1MΩ; Max In: +20dBu

OUTPUT JACK

Audio output jack. Output impedance 660Ω; Max Out: +22dBu

FOOTSWITCH & STATUS LED

The footswitch engages or bypasses the effect. The status LED lights when the effect is engaged and is off while in bypass.

Sets the output level of the Spruce Goose.

GAIN KNOB

Adjusts the amount of gain and distortion. As you turn this knob clockwise, your signal gets louder and more saturated.

LIFT SWITCH

LIFT gooses the input signal before it hits the overdrive circuit. The mid position provides 9dB of gain, which helps get more drive from low output pickups. The high position provides 21dB of gain, adding even more saturation and distortion. The low position does not provide any additional gain.

BASS KNOB

Controls the low frequency EQ of your signal. The bass EQ is flat at noon. As you turn BASS clockwise from noon, the bass response increases. As you turn counterclockwise from noon, the bass response is cut.

TREBLE KNOB

Controls the high frequency EQ of your signal. The higher the setting, the brighter the output signal.

INPUT JACK

Audio input jack. Impedance: 680kΩ.

OUTPUT JACK

Audio output Jack. Impedance: 550Ω.

FOOTSWITCH & STATUS LED

The soft footswitch engages or bypasses the effect. The status LED lights when the effect is engaged. The LED is off in bypass. The Spruce Goose employs True Bypass with a mechanical relay.

Hell Melter

Electro Harmonix — Tue, 25 Apr 2023 20:48:35 +0000

OUTPUT JACK

Audio output from the Hell Melter.

INPUT JACK

Audio input to the Hell Melter.

NORM / BURN SWITCH

Switches between “Normal” and “Burn” Modes: Normal Mode: The famous vintage chainsaw distortion sound. Burn Mode: A custom, modernized distortion sound, utilizing higher voltage rails and alternative clipping options. This results in a less compressed and more open distortion sound with a more pronounced attack.

LEVL KNOB

Adjusts the overall output level of the Hell Melter. Turn clockwise for more output. More output is available than on the original ‘chainsaw’ circuit.

DISTORTION KNOB

Adjusts the amount of distortion and saturation, from a light grind to a roaring chainsaw. Turn clockwise for more distortion.

MID LVL KNOB

Provides active boost or cut to the mid frequency, with the frequency set by the MID FREQ knob. The middle position leaves mid frequencies flat.

HIGH KNOB

Provides active boost or cut to high frequencies. The middle position leaves high frequencies flat. Tip: the frequencies controlled by the HIGH Knob are slightly lower than a typical ‘treble’ control, allowing you to produce searing highs without a lot of treble harshness. To emphasize even higher ‘treble’ frequencies, turn the HIGH knob below the middle position, and increase the LEVEL knob to re-emphasize treble.

LOW KNOB

Provides active boost or cut to the bass frequency range. The middle position leaves bass frequencies flat.

MID FREQ KNOB

Adjusts the frequency boosted or cut by the MID LVL knob. Turn the knob clockwise to increase the frequency.

DRY LVL MINI KNOB

Adds clean, undistorted input signal to the output. As the knob is turned clockwise, the amount of dry signal increases. At the minimum position, no dry signal is mixed into the output. Tip: this is especially useful to maintain note clarity when stacking the Hell Melter with a dirty amp or another gain pedal.

GATE MINI KNOB

Removes unwanted hum by adjusting the noise floor threshold. The gate mutes the OUTPUT jack when the signal at the INPUT jack is below the threshold setting of the GATE knob. As GATE is turned clockwise, a louder guitar signal at the INPUT jack is required to unmute the OUTPUT jack. Set GATE fully counter-clockwise to disable.

EFFECT FOOTSWITCH & RED LED

This footswitch engages or bypasses the effect. The LED lights when the effect is active. The Hell Melter employs high quality buffered bypass.

BOOST FOOTSWITCH & YELLOW LED

This footswitch engages Boost Mode, adding extra gain at the input of the circuit, and adjustable volume boost.

BOOST LEVEL INTERNAL TRIMMER

This trimmer controls the additional volume added when Boost Mode is active. To access it, remove the 4 screws on the back plate of the Hell Melter, and locate the trimmer next to the BOOST Footswitch. Taking care not to touch the rest of the circuitry of the board, turn this trimmer clockwise using a small flat-head screwdriver to increase the volume boost. At the minimum position, Boost Mode provides no volume boost.

PANIC BUTTON

Press the PANIC button to reset the USB connection to the computer. This is useful if the BMπHP becomes unresponsive to its software plugin either by not processing audio or no longer responding to control movement or automation.

USB 2.0 TYPE B PORT

Standard USB port located on the rear panel. Connect the supplied USB cable, or any other standard USB cable, to this port to provide both power and a data connection the BMπHP. You must connect the USB cable to the BMπHP to use it as a Hardware Plugin. Power for the BMπHP may be obtained from the USB cable or from the supplied AC Adapter.

9V POWER JACK

Plug the output of the factory-supplied EHX9.6DC 200mA AC adapter into the 9V power jack. The BMπHP draws 120mA at 9VDC with a center negative plug. The BMπHP accepts Boss® and Ibanez® style AC Adaptors capable of delivering at least 150mA.

STEREO HEADPHONE OUTPUT JACK

1/4” stereo output jack located on the rear panel. Both the Left and Right Output jack signals are also routed to the Headphone output jack. Use the Headphone LVL knob to adjust the volume at the Headphone jack.

DIRECT MONITOR ILLUMINATED BUTTON

When enabled, DIRECT MONITOR sends the signal headed to the ADC to the stereo output jacks and to the Headphone output located on the rear panel. This is particularly useful when using the BMπHP as a USB audio interface for recording new audio tracks. Note: the DIRECT MONITOR switch is disabled when using the BMπHP as a standalone guitar pedal. In this case, the audio output is always sent to the stereo output jacks and Headphone output.

HEADPHONE LEVEL KNOB

Controls the volume level at the Headphone output jack on the rear panel.

USB STATUS LIGHT

Lights red when the BMπHP is locked onto your computer’s USB. The same LED lights green when a proper audio connection has been made between the software plugin and the Hardware Plugin.

USB GAIN KNOB

Controls the signal level of the audio sent to the computer before it hits BMπHP’s internal A/D converter (ADC). Rotate GAIN clockwise until you see one or both CLIP LEDs light. Then rotate it counter-clockwise a bit so that the CLIP LEDs remain off. This will ensure a large enough analog signal is converted to digital audio without exceeding the digital audio’s total range.

CLIP L & R LEDS

LEDs will light when the audio signal into the ADC is clipping. If the LEDs light up, the audio signal is too loud for the ADC and the digitized audio signal will be distorted on its loudest peaks. Use the GAIN knob to set the right amount of signal into the ADC

VOLUME KNOB

Output volume control for the Big Muff section.

SUSTAIN KNOB

Adjusts the amount of sustain and distortion.

TONE KNOB

Provides a range of sounds from high treble to deep bass. As you turn the TONE knob clockwise, treble increases and bass decreases.

TONE BYPASS ILLUMINATION BUTTON

When enabled, the BYPASS button completely bypasses the Big Muff’s TONE knob and analog EQ, essentially removing the TONE knob from the circuit. When the BYPASS button is disabled, the TONE knob is active and will allow users to sculpt their Big Muff sound. Press the BYPASS button to enable or disable Tone Bypass. If the button is lit, the TONE knob and its circuitry is bypassed.

TONE WICKER ILLUMINATION BUTTON

The Wicker effect opens up the Big Muff’s bandwidth allowing more high frequency signal to pass through for a bright and clear top end. Disable Wicker to obtain the classic Big Muff π sound. Press the WICKER button to enable or disable the Wicker effect. If the button is lit, the Wicker effect is enabled.

PRESET KNOB & DISPLAY

The single digit LED display indicates the current preset number selected using the preset knob. The PRESET is active if the LED above the PRESET footswitch is lit. If this LED is not lit then you are in LIVE mode, where the current knob positions indicate the actual Big Muff setting.

R INPUT

Instrument/Line level, 1/4” unbalanced input jack. Plug your instrument or output from another effects pedal into this jack. Use this jack with the MONO/L INPUT jack for stereo use. The input impedance presented at this jack is 2MΩ. The maximum allowable signal level is +9.0 dBu. The MONO/L input routes to the Right input if no plug is inserted into R INPUT jack.

MONO/L INPUT

Instrument/Line level, 1/4” unbalanced input jack. Plug your instrument or output from another effects pedal into this jack. If you use just one input, we recommend using the MONO/L input. The input impedance presented at this jack is 2MΩ. The maximum allowable signal level is +9.0 dBu.

R OUTPUT

1/4” unbalanced output jack. The Right output signal is sent through this jack. In Bypass, the dry signal present at the Right input jack is output to the R OUTPUT jack. If a plug is not inserted into the Right input jack then the Left signal is output on the R OUTPUT jack in both effect and bypass modes. The source impedance of the R OUTPUT is 400Ω.

MONO/L OUTPUT

1/4” unbalanced output jack. The Left output signal is sent through this jack. In Bypass, the dry signal at the Left input jack outputs to the MONO/L Output jack. The source impedance of the MONO/L OUTPUT is approximately 400Ω.
