Electro-Harmonix STRING9 String Ensemble (EHX Pedal Demo by Bill Ruppert)

Electro-Harmonix

collapse expand iconDescription

The Electro-Harmonix STRING9 effects pedal transforms your guitar tone into nine different string ensemble and string synthesizers sounds without special pickups, MIDI or instrument modifications. It relies on the same technology powering all EHX 9 Series pedals, and includes the signature EHX Freeze effect on three of the presets to sample or hold notes and chords with infinite sustain. The STRING9 is equipped with independent Effect and Dry volume controls, so players can precisely tune their mix at the Effects output jack, plus a Dry output jack that always outputs the input signal at unity gain. Controls 1 and 2 have been designed to adjust specific parameters for each of the nine programs, adding usability and flexibility to each sound.

A rotary switch on the STRING9 allows the player to select the sound of their choice from the following options:

  • SYMPHONIC: Recreates the sound of a large symphony orchestra and features an octave-down effect on the lower range of the guitar
  • JUNE-O: Emulates the Juno analog string synthesizer sound
  • PCM: Sound of a small string section sampled by a vintage PCM keyboard, producing a warm vintage string sound
  • FLOPPY: Emulates the sound of an Orchestron optical disc playback sampler, warble included
  • AARP: Emulates the classic ARP Solina string synthesizer
  • CREWMAN: Emulates the Crumar Performer analog string and brass synthesizer
  • ORCH FREEZE: Orchestral sound with EHX Freeze effect
  • SYNTH FREEZE: String synthesizer sound with EHX Freeze effect
  • VOX FREEZE: Mellotron choir and strings sound from the EHX MEL9 with EHX Freeze effect

    I mostly play my bass in stereo. This will used on the bridge PU only. My first impression is that it tracks very well even the low notes. It seems to work pretty good below the low A too. Like most effects, it could be overused… I did get a manual with it and the power supply.

  • Excellent sounds but no manual, no instructions...

    The Electro-Harmonix STRING9 String Ensemble and String Synthesizer effects pedal does track polyphonic strumming, not just single-note lead or melody playing. It’s designed to transform your guitar's signal into various string ensemble and synth-style textures—similar to orchestral strings, Mellotron-type voices, and other layered string sounds. Unlike monophonic synth pedals, the STRING9 can handle chords and strummed guitar parts, making it suitable for rhythm as well as lead playing. That said, for best results: Clean, precise playing helps—excessive fret buzz, string noise, or complex voicings with lots of overlapping notes might cause muddier tracking. Using the neck pickup and rolling off some tone (as per EHX recommendations) often improves tracking and tone. It tracks better with standard tuning and regular guitar strings (not too heavy gauge).

    This type of pedal doesn't work well with a bass.

    Should I assume this only works with magnetic pickups? ( no piezo sound with this pedal )?

    Sure it will . A pedal doesn't "understand" the source. It will process any signal it receives.
