From the vendor
Project overview:
Julio comes with a myriad of controls that allows you to dial in all types of classic and unique chorus/vibrato sounds that can blend together in unusual ways; get mild smooth chorus, seasick vibrato, and everywhere in between.
Introduction
We all know that the market for boutique wobble boxes is highly saturated; but, from time to time, there is a chance of finding unique pedals that can push musicality as hard as sound quality. Julio is one of those gems, a genuinely innovative circuit created with a think-outside-the-box type of mentality.
With controls like Depth, Rate, Blend, and a Shape switch, you can dial in all types of classic and unique chorus/vibrato waves. Some settings give a familiar feel while others go directly into unknown territory.
A special feature of the Julio is the Lag control. The Lag knob lets you set the center delay time that the LFO effect modulates from. This knob adds a new dimension to the traditional Chorus/Vibrato landscape, from smooth and tight modulation at lower settings to warbling detune at maximum.
If you crave shimmering textures and sensuous motion in your clean tones, Julio is the pedal that will grant you all.
