The polyphonic Electro-Harmonix SYNTH9 Synthesizer Machine transforms your guitar or bass with 9 presets that were precisely tuned to emulate the most sought-after, vintage synthesizer sounds ever. From searing lead synths to spacey synth pads and deep, funky, synth bass grooves, it’s all accessible. The SYNTH9 is also super easy to use with DRY volume, SYNTH volume, CTRL1, and CTRL2 knobs that provide precise control over each preset’s parameters. The SYNTH9’s usable tracking range extends up to about the 23rd fret on the high-E string of a standard guitar and down to the open A-string on a bass guitar. Use the SYNTH9 with a B9 or C9 Organ Machine as well as the KEY9 Electric Piano Machine and MEL9 Tape Replay Machine to create your mega-keyboard setup. Press the BYPASS footswitch to toggle the SYNTH9 between buffered Bypass and Effect mode. The status LED lights up when in Effect mode. The 1/4-inch input jack lets you plug your instrument or the output of another effects pedal. The SYNTH OUTPUT jack outputs the mix set by the DRY and SYNTH volume controls. The DRY OUTPUT jack outputs the signal present at the INPUT jack through a buffer circuit. If you dig the kind of classic synth sounds made famous on recordings by groups like ELP, EVH, Kraftwerk, Joy Division, P-Funk, Peter Gabriel, and more, EHX thinks you’ll love the SYNTH9.
