Get multiple bass tones with the Electro-Harmonix BASS9, a pedal designed for electric guitars. Use this pedal to approximate the sound of a P Bass, a baritone-style guitar for Americana, the timbre of classic bass synthesizers, and more.

In addition to modeling classic tones, the BASS9 will allow you to drop your signal one or two octaves without glitchy artifacts. Polyphonic tracking means you can even play chords with this pedal.

Two outputs are provided so you can split your signal if you wish. Send dry, unprocessed signal to your regular amp, and send processed tone to a secondary amplifier. Independent volume knobs are provided for the dry and effected outputs.

Three other controls are on hand. A mode selector knob allows you to set the bass effect, while the function of the CTRL 1 and CTRL 2 knobs change depending on the effect type. The bypass circuitry is buffered to preserve your signal's tone across long cable runs. A power supply is included.

Modes at a Glance

  • PRECISION: An emulation of a popular type of electric bass. CTRL 1 controls the sub-octave, mixing between 1 octave down (counter-clockwise position) and 2 octaves down (clockwise position). CTRL 2 adjusts your tone, which is modeled after the original instrument’s tone control.
  • LONGHORN: Inspired by the Danelectro 6-string basses from the ‘50s, this patch is great for copping baritone style tones. CTRL 1 adjusts the pitch in half steps from -1 octave to unity. CTRL 2 controls a vintage tremolo effect which increases in depth and rate as the knob is turned up. Ring modulation effects are generated when the knob is turned past 2 o’clock. Also, use the Longhorn preset to detune your guitar for metal.
  • FRETLESS: Emulation of both electric and upright fretless basses. CTRL 1 controls the buzzy growl sound of a fretless instrument. CTRL 2 adds a Jaco-style chorus effect which intensifies as the knob is turned up. 
  • SYNTH: A bass synthesizer sound modeled after the Taurus synthesizer. Use CTRL 1 to adjust the synth’s note range between octaves and fifths. CTRL 2 adjusts the synthesizer’s envelope filter range. Higher settings of CTRL 2 makes for brighter and wider filter sweeps.
  • VIRTUAL: This patch that allows you to adjust your bass’s body density and neck length. CTRL 1 adjusts body density; higher settings produce longer, piano-like sustain. CTRL 2 adjusts neck length, where the length increases as the knob is turned clockwise.
  • BOWED: A classic bowed bass sound with adjustable attack. CTRL 1 controls sub-octave mixing between 1 octave down and 2 octaves down. CTRL 2 adjusts the bow’s attack speed. As you turn up the knob, the attack speed slows. The attack effect is fully polyphonic.
  • SPLIT BASS: This patch provides a sub-octave effect on all notes below F#3—the F# can be found at the fourth fret of the D-string on a standard guitar. It does not pitchshift notes above G3. This allows a guitar player to play bass lines with the lower two strings of a guitar and chords or melody with the highest three strings. CTRL 1 adjusts bass tone by adding upper harmonics as the knob is turned clockwise. CTRL 2 provides an envelope filter / auto-wah effect on all notes you play. As you turn CTRL 2 up, the wah effect intensifies. 
  • 3:03: This is a polyphonic emulation of one of the most sought-after vintage bass synthesizers. CTRL 1 adjusts the filter’s envelope sweep depth or total range while CTRL 2 sets the envelope speed. 
  • FLIP-FLOP: Inspired by the Electro-Harmonix Octave Multiplexer, this patch provides a ‘70s style logic driven sub-octave generator, minus the glitches of the original. CTRL 1 handles sub-octave, mixing between 1 octave down and 2 octaves down. CTRL 2 adjusts the frequency of a synth-like low-pass filter.

Quick read, entertaining & informative
Format: Hardcover
This book can be enjoyed on several levels. It could be tongue-in-cheek or satire, but is also backed by facts and conjecture by one of the world’s greatest scientific thinkers. I think Dr. Tyson had fun writing it, and i certainly had fun reading it. And I learned a lot.

Aliens: Know what to expect!
Format: Audiobook
This is a really fun review of Earth's obsession with alien life, what we have historically expected of aliens--and what they might expect of us. If you are a long-time listener of the author or a viewer of his YouTube show (Star Talk), you have probably heard much of what NDT has to say on this subject already--here and there as he picks his way thru the universe, but why not listen to him now again as he focuses his energies on just this alien subject? If you want an enjoyable read, it will be worth your time. If you're not a long-time listener of NDT... and you have any interest in aliens at all, then you DEFINITELY should give this book a go. It is full of thoughtful insights from a man who has devoted his life to the science and 'cultural impact' of the stars. I listened to the Audible version wherein NDT reads his own book aloud for you. His efforts really allow you to gain his insights... And his strong sense of humor--in equal doses. 5 Stars

My son is actually motivated to do a workbook
Format: Paperback
My Kindergartener finished homeschool online early and we have been doing a page a day and he loves it and loves to earn a sticker after each day and put it on his chart. I love how engaging the workbook is and how it introduces some 1st grade concepts. Would highly recommend.
