Mint Used Walrus Audio Fundamental Chorus Pedal - Black / Purple w/ Box
Description from Walrus Audio:
The Fundamental Chorus is a digital emulation of a classic analog chorus, recreating bucket brigade modulation. With three types of chorus algorithms to select from, you can get sounds ranging from gentle modulation all the way to 80's tri-chorus.
Rate: Controls the rate of the modulated LFO. A higher rate will produce a faster and more pronounced pitch modulation, while a lower rate will produce a slower and more subtle effect.
Depth: Controls the depth of the modulated LFO. This affects the amount of pitch modulation applied to the affected signal. 
Mix:  Controls the mix of the affected signal and the original clean signal. All the way to the left outputs a fully clean signal, and all the way to the right outputs only the modulated signal. 
Slide Switch – The slide switch allows you to change between three different flavors of the pedal. 
Light – Emulates a traditional analog chorus with warm, lush, and organic tones.Medium – Adds multiple taps to further modulate a classic chorus.Heavy – Emulates a classic Eighties effect, the LCR tri-chorus, which is known for its rich and complex modulated sound.
Comes with box - the box is actually from a Walrus Audio Fundamental Delay pedal but it still fits the same.
