Introducing the Electro-Harmonix Micro Synth XO, a versatile tool for any guitarist looking to explore the realm of synthesizer effects. It's more than just a pedal - it's a creative powerhouse designed to unlock a universe of sonic possibilities.
This compact, all-analog synth pedal is capable of generating a broad spectrum of sounds, from the classic vintage warmth of early Moog synthesizers to innovative custom creations that push the boundaries of music.

The Micro Synth XO boasts four mixable voices: Guitar, Octave, Sub-Octave, and Square Wave, each offering a different character to enrich your sound.

This pedal has enormous range of sounds in it. When you play with some of the sliders, they change all the characteristics of the sound this pedal produces. Sure, i bought it for 1100 TL means 350 USD and i am sure that i can always use it when i need a strange, 70's, fuzzy, ..... kinda synth sounds. Plus i can use it with deep house music too, so check it out if you see one.
