Harmonix - Micro Q-Tron Envelope Filter Pedal MQTRON - Silver

Electro-Harmonix Nano Q-Tron Envelope Controlled Filter. A compact version of the classic Micro Q-Tron Envelope Controlled Filter known for its organic, analog sound and expressivity. Envelope controlled filter is an effect type that ventures beyond the mainstream yet is equally at home in a wide range of genres and equally effective on guitar, bass, keys, horns and more. Electro-Harmonix is a pioneer in this effect category and has been making envelope controlled filter pedals since the 1970s! The Nano Q-Tron springboards off that deep heritage. Here’s how it works: The Nano Q-Tron responds to the user’s playing style and dynamics. The volume of the input signal it receives (also called the envelope) controls the cutoff or center frequency of a swept filter. This allows the Nano Q-Tron to create tone-altering effects ranging from subtle to dynamic, auto-wah to ultra-funky. It’s all about how you play and it’s super interactive. Product Highlights: Vol (Volume) knob which controls the pedal’s output volume. Drive Control adjusts its filter sweep sensitivity and how the pedal responds to the user’s playing dynamics. Q Control sets the peak bandwidth of the filter and determines how subtle or dramatic the effect will be. LP BP HP Mode Switch controls what frequency range the filter will pass. LP (low pass) emphasizes the lows, BP (band pass) the midrange and HP (high pass) the highs. Pedalboard friendly, compact, rugged enclosure. True Bypass switching. Comes equipped with a 9Volt battery and can also be powered by an optional 9Volt power supply. Product Features: 9V Power Jack: An optional 9VDC, center-negative power supply can be connected to the power jack to provide power without a battery. The Nano Q-Tron requires 10mA at 9VDC on a center-negative plug. Do not exceed 12VDC at the power jack. Volume Knob: Adjusts the overall volume at the OUTPUT jack. As VOL is turned clockwise, the output level increases. Use VOL to match the effect volume to your bypass volume or give the effect a volume boost. Drive Knob: Sets the envelope sensitivity gain, which in turn controls how wide the filter sweeps. The higher the DRIVE setting, the more the filter reacts to your playing and the higher in frequency the filter will jump when you play a note. Turn DRIVE clockwise for a wider filter sweep or counterclockwise to reduce the sweep range. If you turn DRIVE up too far, the filter sweep will max out at its highest frequency (approximately 3.5kHz) and remain at the highest frequency until the note has fully decayed. Louder instruments will typically use lower DRIVE settings while quieter instruments require higher settings. When learning the Nano Q-Tron, start with DRIVE at 12 o'clock. Q Knob: Sets the bandwidth of the filter. As Q is turned clockwise, the filter sounds more resonant or peakier, making the envelope effect more dramatic. Low settings of Q yield a less intense filter curve. Start with Q set to about 2 o'clock for a middle-of-the-road filter intensity. Mode Rotary Switch (LP/BP/HP): Determines the frequency range that the filter allows to pass through, LP (Lowpass) mode emphasizes low frequencies, BP (Bandpass) middle frequencies, and HP (Highpass) high frequencies. Amp Jack: Audio output from the Nano Q-Tron. In bypass mode, the AMP jack is directly connected to the INPUT jack. Input Jack: Audio input to the Nano Q-Tron. Footswitch and 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 Nano Q-Tron employs True Bypass. Product Specifications: Circuit: Analog. Bypass: True Bypass. Audio: Mono. Power Supply: 9V battery included (optional 9.6VDC-200mA power adapter not included). Dimensions (in): 4.5 x 2.75 x 2.1. Current Draw: 10mA. Year Released: 2021. UPC: 683274012384.

One of Electro-Harmonix’s most popular effects, there are many reasons to love the POG2. One major reason being its unique attack filter, applying attack envelopes to each individual note played whether in single notes or in a chord. This creates a very musical, multi-voice effect that’s extremely adaptive to any musical style. This polyphonic attack filter is the core of the PICO Swello generating polyphonic and reverse sounds with the addition of a modulated low-pass filter for even more expressive tones. Implemented subtly, the Swello adjusts your guitar’s attack to sound smooth and flowing even while playing fast lines and arpeggios. Laying on the effect more heavily creates dramatic swells perfect for shaping gently shifting ambient soundscapes and synth style pads. The simple 4-knob control layout is easy to drive starting with the heart of the pedal, the ATTACK knob. Turn up ATTACK to go from a quick, gentle attack time to slow, long swells. VOL controls the overall output and is useful for making up for the perceived low volume of long attack effects. The rest of the controls apply to the Low-Pass Filter. The Filter Button engages the LPF with adjustable low and high resonance settings. The FREQ control adjusts the cutoff frequency of the LPF. The MOD knob controls the depth and direction of the LPF envelope for upward or downward filter sweeps over a narrow or wide range of frequencies limited by the cutoff frequency. The LPF’s modulation timing is tied directly to the ATTACK knob setting. Combining the LPF with the Attack Envelope brings added musicality and expressiveness to fan-favorite effect, now in its very own pedal.

Electro-Harmonix Op Amp Big Muff Pi Fuzz / Distortion / Sustainer Pedal. Faithful re-creation of the original late-70s Op-Amp Big Muff Pi! With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new EHX Op-Amp Big Muff Pi —sometimes also referred to as the IC or V4 Big Muff— has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching. “The Op-Amp Big Muff was popularized by the brilliant Billy Corgan who first used it on the Smashing Pumpkins’ epic 1993 album Siamese Dream. After he was videotaped playing and talking about the reissue, Billy stated: ‘The magic’s still in the box, I can still get what I’m looking for!’” – Mike Matthews. The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It’s a sound that’s been described by noted Big Muff collector and historian, Kit Rae, as: “a huge, crushing Big Muff sound with more crunch… great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads.” Product Highlights: A faithful reissue of the original classic circa 1978. Iconic sound and vibe that’s coveted by guitarists. Controls for Tone, Sustain and Volume, plus a Tone Bypass switch. True bypass switching for maximum signal integrity in bypass mode. Rugged, compact, die-cast package... pedalboard friendly. 9V battery included. Product Features: Volume Control: Sets the output level. Sustain Control: Adjusts the amount of sustain and distortion. Tone Control: Provides a range of sounds from high treble to deep bass. Tone Switch: Removes the TONE control from the circuit. Amp Jack: This is the audio output. Input Jack: This is the audio input. Footswitch and Status LED: Toggle between effect bypass modes. When the LED is lit, the effect is active. Product Specifications: Circuit: Analog. Bypass: True Bypass. Audio: Mono. Power Supply: 9V battery included (optional 9.6VDC-200mA power adapter not included). Dimensions (in): 4.5 x 2.75 x 2.1. Current Draw: 5mA. Year Released: 2017.
