Proper bass sound - without hassle

It's usually pretty difficult to get your standard electric guitar sounding like a bass. Getting that natural, deep tone often necessitates modifying your guitar, fitting specialised pickups, or using MIDI. But all of that hassle and fuss is eliminated by the Bass9. EHX have developed a new algorithm that takes the signal of your guitar, transposes it down by one or two octaves (depending on how low you want to go), and delivers a stunning bass tone that sounds natural and authentic.

A huge range of sounds to play with

You'll never be limited in the bass tones you can use in your music. The Bass9 comes loaded with nine different voices to choose from. So there's a gigantic offering of different sounds available. With voices inspired by some of the most iconic basses in history, as well as synth modes, and even a setting that lets you turn your instrument into a hybrid between bass and guitar, you have the ultimate in versatility.

Masterful FX innovation from EHX

Electro Harmonix have been doing what they do best for over 50 years now: making guitar pedals at the very top of their game. The Bass9 is yet another top-class offering. And EHX's pedigree means they know a thing or two about making a pedal usable. They've made sure to give the Bass9 a straightforward, easy-to-use interface that makes it quick and easy to find the right bass tone for you. Perfect for quickly adjusting your sound on-stage - this has been designed with the musician in mind.
