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.

Perfect Summer Suit for Boys – Stylish and Comfortable!
Size: 5, Color: Light Green
I’m so impressed with this **boys' linen summer suit**! 👔🌞 It’s the perfect outfit for warmer weather while still looking sharp and stylish. The **linen fabric** is lightweight and breathable, making it ideal for those hot summer days. My son looked fantastic in it, and he was comfortable all day long, which is a big plus! The suit fits **true to size**, and the cut is modern yet classic. The **jacket** has a great, tailored look without being too stiff, and the **trousers** are just the right fit—not too baggy or too tight. It’s a very **polished** look for events like weddings, family gatherings, or holiday parties. I also love that the **color options** are vibrant and fresh, perfect for summer. The suit is **easy to care for**—I was worried about linen wrinkles, but it’s held up well after a few washes, and the fabric still looks crisp. Overall, this **boys' linen summer suit** is an excellent purchase for any special occasion or just to make your little one look extra sharp during the summer months. **Comfortable, stylish, and durable**—highly recommend! 🌟👔

Nice summer suit for my son
Size: 6, Color: Light Green, Size: 6, Color: Light Green
I got this linen suit for my 7 year old son and it looks really nice on him. The set comes with the blazer, vest, and pants, which makes it look very polished when worn together. The material is lightweight and breathable, which is great for warmer weather. It has that classic linen look but still feels comfortable enough for kids to move around in. My son wore it for a few hours and didn’t complain about it being uncomfortable. I also like the little details like the pockets, the adjustable back on the vest, and the adjustable waistband on the pants. Those features really help with getting a better fit. Another nice thing is that you can mix and match the pieces. He can wear the vest and pants for a slightly more casual look or the full suit for more formal occasions. Overall it’s a really nice suit for kids, especially for events like weddings, family gatherings, or school events. My son looked great in it and it worked perfectly for the occasion.

A good First Communion suit
Size: 6, Color: White, Size: 6, Color: White
This suit looks and feels really nice even though it’s not 100% linen. My son is an average size 7 year old, but I got a size 6 so that the fit would be nice and snug and not loose and baggy. It was the right choice. Comes with a bow tie which is nice, a tie (which is very cheap and poorly made) and a pocket square.

This little suit for boys is very stylish. I bought it for my grandson for a wedding occasion and it looked very nice. The fabric is not too thick so for the summer wedding it was great. I pick the blue color and it looked fantastic!
