Electro Harmonix Bass MicroSynth w/ Power Supply Analog Bass Guitar Synth Pedal

Description

The Bass Micro Synthesizer has the same feature set as the Micro  Synthesizer, but includes a trigger and filter sweep range especially  tailored for bass guitar. The same fat analog synth textures give your  bass a whole new range of possibilities: from percussive stabs to  backwards-sounding bowed sounds.

Start, stop filter frequency sliders with adjustable rate for full control over the filter's sweep direction and speed
Adjustable filter resonance control
Adjustable attack time control for fading-in notes
Tough and compact die-cast chassis
96DC-200BI power supply included

The XO BASS MICRO SYNTH can create many of the most popular analog  lead synthesizer textures at a fraction of the normal cost for such  capabilities.  Its four voices: GUITAR, OCTAVE, SUB-OCTAVE, and SQUARE  WAVE are completely independent and fully mixable.  The BASS MICRO SYNTH  can modify these signals with envelope control for a variety of “bowed”  and “blown” sounds.  In addition, a sophisticated swept filter control  allows highly variable frequency adjustments to be made to the signal.   When combined, these controls offer the user a creative capability that  is virtually limitless.
PREAMP GAIN ADJUSTMENT
The preamp gain in the Bass Micro Synth has  been set at the factory for use with a bass equipped with single-coil  passive pickups. If you will be using another instrument with higher or  lower output, it may be necessary to readjust this setting. A  screwdriver or alignment tool with a tip width of no more than 1/16” is  required. To access the preamp gain adjustment, remove the bottom plate  from the Bass Micro Synth. Look for the small trim pot in the lower left  corner of the circuit board, it is labeled TRIM1 GAIN TRIM. Turning the  trim pot clockwise will increase the preamp gain. Turning it  counter-clockwise will decrease preamp gain. Please do not touch any  other components when the bottom plate is removed or you risk damaging  the circuit board or the components.
OPERATION
The Bass Micro Synth’s controls operate as described below.   In all cases, high-numbered control settings increase the level of the  given effect.
FOOTSWITCH
and Status LED — The Footswitch selects either effect mode  or True Bypass. When the Status LED is lit, the Bass Micro Synthesizer  is in effect mode. When the Status LED is off, the Bass Micro Synth is  in True Bypass mode.
TRIGGER
— Determines the input volume at which the filter circuits  will “turn on.”  It does not affect any other circuitry.  If the TRIGGER  is set too high, the filter may “stutter” due to multiple triggering.   This is especially true if chords are played.  It is best to set the  TRIGGER at exactly the sensitivity needed for your playing.
The next four controls of the BASS MICRO SYNTH comprise the VOICE  MIXING section: GUITAR, SUB-OCTAVE (one octave below), OCTAVE (one  octave above), and SQUARE WAVE. Each voice is completely independent and  can be mixed with the others in any degree.  Please not the following  voice characteristics:
GUITAR
- Controls the output volume of the input signal through the filter.
SUB OCTAVE
— Controls the output volume of the Sub-Octave. The Sub-Octave
effect only tracks single notes.
OCTAVE
— Controls the output volume of the Octave. The Octave only  tracks single notes. This voice contains a small amount of harmonic  distortion for added richness of tone.
SQUARE WAVE
— Controls the output volume of the Square wave. Intensity  of this voice is also determined by instrument attack or volume. In all  other respects it operates in a similar fashion to a standard distortion  device.
ATTACK DELAY
— Determines the time required for the voice signals to  reach full volume.  Higher-numbered settings can completely remove the  initial attack of the instrument.  Different delay times contribute  greatly to the characteristic sounds of various instruments.  It is  recommended that you synchronize your playing to the speed setting of  the ATTACK DELAY.
The final four controls comprise the FILTER SWEEP section.
RESONANCE
— Affects the degree of sharpness, or “Q” of the filter.   Higher settings will produce a more emphasized filter sound and also add  a slight boost to the signal.
START FREQUENCY
- Determines the frequency at which the filter sweep begins.
STOP FREQUENCY
— Determines the frequency at which the filter sweep  ends.  This is also the “resting frequency” of the filter, and if the  START and STOP controls are set at the same level no sweep will occur,  though the filter will provide emphasis of that particular frequency  band.  In addition to lead synthesizer sounds, START and STOP controls  can be used to simulate attack, decay, and harmonic content of acoustic  instruments.
RATE
- Determines the speed at which the filter sweeps from START  FREQUENCY to STOP FREQUENCY.  It is recommended that RATE be  synchronized with your playing speed.
SOUND TEMPLATES
- The sample settings include with these instructions  will help you get familiar with your BASS MICRO SYNTH and its controls.   Once you’ve tried all the sample settings, feel free to experiment to  develop your own unique palette of sounds.  You can record your new  settings in the blank templates provided.
-Power-
9V Power Jack — Connect the output plug of the supplied AC Adaptor  into the 9V power jack at the top of the Bass Micro Synth. The Bass  Micro Synth’s maximum current requirement is 55mA at 9VDC. The polarity  of the power jack is center negative. The maximum allowable power supply  voltage is 12VDC.
