Turn Your Guitar Into 9 Vintage Synths

Continuing their line of effects pedals designed to render keyboardists obsolete (just kidding), the Electro-Harmonix Synth 9 Synthesizer Machine pedal allows you to coax classic synth tones from your guitar or bass. And it doesn't require a special pickup system either — just add it to your pedalboard like any other effects pedal. Nine presets give you access to some of the most iconic synth sounds from the '70s and '80s. And thanks to an extremely wide playable range, the Electro-Harmonix Synth 9 pedal delivers precise tracking with both guitar and bass.

Precision tracking across a wide playable range

Just like the Electro-Harmonix B9, C9, Key9 and Mel9 emulation pedals, the Synth 9 Synthesizer Machine boasts ultra-precise tracking for glitch-free performance. The playable range is huge — it'll track accurately on your guitar all the way up to the 23rd fret on your high E string. On bass, the Synth 9 tracks accurately all the way down to your open A string.

Electro-Harmonix Synth 9 Synthesizer Machine Pedal Features:

  • Synthesizer emulation pedal with 9 presets for electric guitar and bass
  • Precision tracking from the 23rd fret on a guitar's high E string, down to the open A string on bass
  • Separate Dry and Effect outputs allow for dual amp setups
  • CTRL1 and CTRL2 knobs offer preset-dependent controls like filter envelope depth, voice intervals, and more
  • 9-volt power supply included

Superb!!!

I ve had the Synth 9 for a while. It s fantastic!!! I own all of the EHX "9" pedals and this is my fav by far. I ve "nailed" the intro to "Mr. Crowley," all of Van Halen s "1984" and "Jump." The tracking, especially the "Solo Synth" setting, is excellent. I play Keyboards pretty well but how cool to have the Synth 9 for a gig that requires a Keyboard part

Excellent guitar synth pedal by EHX!

Without needing a special pickup or MIDI guitar, and using only your 1/4-inch guitar cable, this synth rocks. It's always great to have a guitar synth handy for those special songs. Some of the settings work find with hammer ons, pull-offs, and slides (from my experience), but others require meticulous playing of single notes as with a monophonic synth. The "Vibe Synth" is great with it's delayed vibrato and adjustable intensity. A great pedal that will come in very handy in certain situations. The adjustable and mixable dry and synth signals is also great so you can blend the synth sound with your dry then processed guitar signal--like having a synth doubling with your guitar licks (a great sound especially when separately panned left and right in a stereo field)!

Cool pedal

Very impressive sounds - you are still using your guitar to play a synth so it is not perfect, but it beats buying a synth and learning to play it and you don't need a midi guitar either. I would recommend to add to almost any pedalboard as it is a very fair price for what you get.

EXH Synth 9

This is the best synth pedal for a bassist. It claims to track to a low A but using my stingray it tracks all the way down to low E. Perfect Oberheim sound. For us old school players the obx sound is just like Mothers Finest funk keyboard without a keyboard player!

Great sounds from the Synth 9

I had always been skeptical regarding guitar synth effects, but after seeing the demo I couldn't wait for the release of it. Great sound! Very easy learning curve. Very intuitive functions. I use it to add fullness and subtle background effects over both rhythm as well as lead riffs. I am completely satisfied with it, as are all of my band mates! This opens up many possibilities to expand and explore your music.
