This polyphonic synthesizer machine is designed to morph your instrument into nine meticulously tuned, vintage synthesizer sounds, ranging from sizzling lead synths to ethereal synth pads and deep, funky bass grooves.
The SYNTH9 is not only a powerhouse of sound but also incredibly user-friendly. It features DRY volume, SYNTH volume, CTRL1, and CTRL2 knobs, allowing you to have precise control over each preset's parameters. The DRY Vol knob manages the volume of the untreated instrument signal at the SYNTH OUTPUT jack, while the SYNTH Vol knob adjusts the overall volume of the selected preset at the same output.

The DRY OUTPUT jack outputs the signal present at the INPUT jack through a buffer circuit, and the SYNTH OUTPUT jack outputs the mix set by the DRY and SYNTH volume controls. The Input Jack is designed to accommodate your instrument or the output of another effects pedal into its 1/4" jack.
Finally, the SYNTH9 features a Bypass Footswitch, allowing you to easily toggle between buffered Bypass and Effect mode. The status LED lights up when in Effect mode, providing a clear visual cue. With the EHX SYNTH9 Synthesizer Machine, you can unlock a world of vintage synthesizer sounds, all from your electric guitar or bass.
