Electro-Harmonix

Notes: Produces volume and reverse swells, backward tape sounds, artificially short staccato notes and bowed instrument effects!

The circa-1980 Electro-Harmonix Attack Decay is a sought after prize among vintage pedal aficionados. Originally called a Tape Reverse Simulator, it's known for producing volume and reverse swells, backward tape sounds, artificially short staccato notes and bowed instrument effects. The freshly designed EHX Attack Decay reinterprets the classic and keeps its cool factor, but adds some modern features for convenience and enhanced functionality.

It can produce a single volume envelope like the original, or, with Poly engaged, put separate volume envelopes on each note you play. The built-in Harmonix fuzz is now a fully controllable distortion with gain, tone and volume controls. The effects loop allows the musician or sound designer to place the volume envelope onto whatever signal is present at the Return jack. Expression pedal/CV input and three user presets give the user total control over their Attack Decay!

Volume envelope manipulation with adjustable Attack and Decay times
Mono mode: one volume envelope at a time, the envelope resets when you play a new note
Poly mode: gives each note you play its own envelope
Built-in, fully adjustable, Harmonix fuzz enhances the volume envelope effect and produces bowed instrument sounds
Built-in effects loop allows for your own pedals to be inserted onto the volume envelope
Expression pedal or CV control over every knob on the Attack Decay
Save and recall up to three presets
Power adapter included

Notes: Buzz. Beep and bloop. Get high on the lo-fi sounds of "old-school" games, toys and terminals!

The Mainframe provides sample rate reduction ranging from 48kHz to 110Hz. A little background... the sample rate is the number of times per second that a sample or snapshot of an analogue signal is taken. For example, CDs (remember them?) had a sample rate of 44.1kHz which means that the original analogue signal is sampled 44,100 times per second.

The sample rate defines the frequency range that can be reproduced while maintaining good fidelity. When the sample rate is reduced the quality of the audio is degraded and aliasing occurs. Aliasing means audible artifacts created when higher frequencies are sampled at an inadequate rate and the result is distortion. The Mainframe's sample rate range is wide enough to take you from sounds that are quite pristine to sounds that are unrecognizable when compared to the input signal.

It also provides bit crushing ranging from 24-bit to 1-bit. What does that mean? Bit crushing is bit depth reduction. Back to the CD example... CDs used a 16-bit bit depth meaning that each of its samples was represented by 16-bits of information. Higher bit depths can accurately represent a greater dynamic range while bit crushing increases the number of sampling errors and creatively degrades the sound to bring us back to those nasty "old school" sounds we love.

The Mainframe's selectable High/Low/Band-Pass filter lets the user shape the artifacts of the bit crushing and sample rate. Another very cool feature is its Sample Rate Tuning Mode where the pedal analyses your input signal in real-time and sets the sample rate to match the pitch of your signal, or a set interval above your signal. This allows you to set the sample rate to match the key of a song, or it will continually adjust the sample rate based on what you play!"

Notes: The polyphonic STRING9 String Ensemble transforms a guitar into nine different string ensembles and string synthesizers while requiring zero modifications, special pickups, or MIDI implementation. It relies on the same technology powering all EHX 9 Series pedals. In a 9 Series first, the STRING9 includes the signature EHX Freeze effect on 3 of the presets to sample and hold notes and chords with infinite sustain.

A rotary switch on the STRING9 allows the player to select the sound of their choice, as follows:

SYMPHONIC: Re-creates the sound of a large symphony orchestra and features an octave down effect on the lower range of the guitar for a full sound
JUNE-O: Emulates the Junor analogue string synthesizer sound
PCM: Sound of a small string section sampled by a vintage PCM keyboard producing a warm vintage string sound
FLOPPY: Emulates the sound of an Orchestronr optical disc playback sampler, warble included
AARP: Emulates the classic ARP Solinar string synthesizer
CREWMAN: Emulates the Crumar Performerr analogue string and brass synthesizer; Floyd in a box
ORCH FREEZE: Orchestral sound with EHX Freeze effect
SYNTH FREEZE: String synthesizer sound with EHX Freeze effect
VOX FREEZE: Mellotronr choir and strings sound from the EHX MEL9 with EHX Freeze effect
The pedal is equipped with independent Effect and Dry volume controls so players can precisely tune their mix at the Effects output jack, plus a Dry output jack that always outputs the input signal at unity gain.

Controls 1 and 2 have been designed to adjust specific parameters for each of the nine programs adding usability and flexibility to each sound.

Notes: Raise the bar when it comes to creating synth effects, sound layers, glissandos, infinite sustain and more!

Building on the synthesis platform of the award-winning Superego, the EHX Superego+ Synth Engine raises the bar when it comes to creating synth effects, sound layers, glissandos, infinite sustain and more. Plus, we've added a complete effects section featuring 11 effects types, an EXP input for effect parameter control/preset recall and an EXT jack for a 3-button controller.

The Superego+ is equipped with the following effects:
DETUNE: pitch detune, EXP pedal controls pitch
DELAY: warm, analog sounding delay, feedback is preset, EXP controls delay time up to 2 seconds
ECHO: pristine digital delay, feedback is preset, EXP pedal controls delay time up to 2 seconds
FLANGE: Electric Mistress style w/filter matrix, rate and feedback. EXP pedal controls rate
PHASE: Small Stone style phase shifting with rate and depth control. EXP controls rate
MOD: pitch-based vibrato or chorus. EXP controls rate
ROTARY: rotary speaker style sound. Depth controls tweeter/horn balance. EXP pedal controls rate
TREM 1: sine wave tremolo. EXP controls rate
TREM 2: square wave tremolo. EXP controls rate
PITCH: pitch shifting effect over a +/- one octave range. EXP controls whammy
FILTER: resonant low-pass filter. EXP pedal controls frequency

The pedal provides enough sound shaping control to please the most sonically adventurous player and is equipped with Dry, Effect, Attack, Decay, Threshold, Layer and Gliss knobs, plus Rate and Depth knobs for the Effects Section. Four foot-switchable Freeze modes: Moment, Sustain, Auto and Latch, plus a Live Effects mode where the dry signal is routed thru the built-in effects and the internal synth engine is disabled, are included.

The polyphonic Superego+ works with guitar as well as other instruments including bass, keyboards, vocals, drums, etc. and comes equipped with an EHX 9.6DC-200 AC Adaptor.
