From the vendor

Project overview

Deluxe drive/distortion pedal. This board inspired by Cornish SS-2 is excellent for those searching for a unique tonal color palette. Pretty much an amp in a box!

Introduction

The Sour Sweet Corn is totally different from any overdrive/distortion effect out there, with many great features that make it one of the sweetest boards on the field. Let’s see them:

It is remarkably perceptive to changes in both Guitar volume and picking articulation. It has an outstanding “bottom end retention,” while the mid-range is sweet and very clean. It preserves all the tonal subtleties of your guitar and is nuanced yet capable of tremendous power and sustain. When using it with a clean amp, it is possible to shift from subtle overdriven amp sounds, through rhythmic crunch, up to a blues’ lead. None less important, all its tonal properties and dynamics of the guitar are preserved even when using this pedal at its maximum gain.

When being fed into a clean, total frequency response amplifier is when this pedal shines the most.

To acquire full knowledge of how the controls, interact, both with themselves and the guitar/amp controls, it is helpful to first connect it up without anything else in line. You can then add the rest of your effects and have that feast of tonal color palette that the Sour Sweet Corn adds to your playing!
