Turn Your Guitar Into a Bass

If you’ve performed as a solo act, you know the pain of having to switch instruments to lay down a bass line. The Bass9 Bass Machine pedal from Electro-Harmonix has solved that issue. This guitar effects pedal allows you to turn your guitar into a bass to record a quick bass loop before jumping back into the lead line. You can choose between 9 awesome presets that cover the legendary bass sounds from Precision to Longhorn, or Bowed to Synth. At Sweetwater, we especially liked the 3:03 setting that captures the genre-defining squelch of the ’80s. If you’re using a looper, this pedal will be perfect for you. Kiss your unwanted instrument changes goodbye and say hello to the Bass9.

Room for customization

With the Electro-Harmonix Bass9 Bass Machine, you can dial in your perfect sound quickly and easily. You start with 9 basic bass sounds and can use the Dry and Effect knobs to dial in your perfect dry/wet balance. Then you can use the Control 1 and Control 2 knobs to shape the sound using key parameters for each bass type. The Bass9 has two outputs — Dry and Effect — to let you route your sound through different amps for even more customization. With the wide variety of tonal options available to play with, you won’t get tired of using Electro-Harmonix Bass9 Bass Machine.

9 Bass Types to Experiment With

  • Precision
  • Longhorn
  • Fretless
  • Synth

  • Bowed
  • Split Bass
  • 3:03
  • Flip-Flop

Electro-Harmonix Bass Machine Effects Pedal Features:

  • Converts your electric guitar into a fat bass

  • 9 great presets covering all genres
  • Separate Dry and Effect outputs for running into different amps

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Well This Pedal is Legit. Lives Up To The Hype

I don't know why anyone couldn't dial in a satisfying bass tone with this pedal. Just tweak it a bit and you'll find a sound you'll like. I do like to use the Precision Bass settings utilizing the neck pickup on a Strat. Sounds really great for looping. I've included a demo of me doing a jam through a Fender GTX100.

Keeper

I buy them and I get rid of them till I found this one.. this is a good age to be alive.. this pedal does exactly what I need it for.. click it and your guitar is a bass and it's that simple.. I don't even own a bass anymore though I miss all of them.. I only have two single pedals now this one and the canyon one.. I went this route for space but if you want a pedal that transforms your signal to bass, then you really don't need to look anywhere else.. you won't be disappointed.. in fact, you'll wish you'd have done it sooner.. good heavy duty materials.. lots of settings to find your pocket for which to get your groove on and fast or slow?; this baby will keep up with you as it tracks you like a jealous girlfriend.. comes with quality power supply but then this company EH?; they only do quality stuff so you can't go wrong and it's virtually a noise free unit which is another reason I use Electro-Harmonix .. also, there's no learning curve if any as you just turn it on play around till you find your sound and leave it there.. if this ever wears out, I will just get another one.. this unit is a keeper.. just do it and Sweetwater has your back all the way from the order to you using it so even don't worry bout it..

Unbelievable

I rely heavily on pitch shifting effects. I already have the pitchfork from EHX, and it's an incredible shifter. With an expression pedal it blows the whammy pedal from digitech out of the water. Its only shortcoming is latency when the effect is fully engaged. The latency when shifting a full octave down with no dry signal mixed in is unworkable. Enter the Bass 9. While this pedal is advertised as a bass modeler, it's really just a fancy octaver.

The entire design is about shifting down an octave with zero latency, and it does this flawlessly. This is exactly what I needed and this pedal does that and much more. The 9 different models are all cool, although the P-bass model really shines. I put this pedal first in my signal chain, and it plays really nicely with my analogman mini compROSSor and my Keeley Neutrino envelop filter.

With a comp and a filter in the chain, you can get all the classic bass sounds with this. Of course if you turn up the dry mix you get unparalleled octaver sounds that sound way better than, say, the POG. Combined with the pitchfork and Mission EP-1, I now have total control over pitch shifting. I love modern technology that has made things like the whammy bar obsolete. Pardon the messy pedalboard. I'm not using any velcro or zip ties until I'm 100% settled on the signal chain, and more adjustments will probably be made.

Great pedal

The bass 9 has many different bass effects that I can apply to a variety of songs. It performs well through a combo amp, but not so much through a bass amp. The overall volume and performance quality loses in the bass amp but not on a combo Otherwise the variety of effects are impressive. The fretless muting the strings actually is one of my favorites. Also the ability to chord with it is a plus.

THE SOLUTION

Iam an old rocker, melodic hard rock/ metal with arthritis. it's painful to play bass guitar on my recordings. so this works great running guitar through it. the P bass sounds very real, and the Taurus pedal sound is a lot like my old non working Taurus pedals. the other bass sounds, like the bowed cello is nice too. so the 27 songs that need bass right now will be much easer to finish. if you need bass guitar sounds as well as other bass instrument sounds, this is a great way to go. and it is a much cheaper solution to an expensive bass guitar. BTW the EH Canyon pedal is real nice on guitar as well. ROCK ON.
