“The Visual Sound V2JH is basically two effects in one pedal, each with separate controls, and each with its own personality. They can be used separately or blended together. Jekyll accurately reproduces the sound of the original TS808 Tube Screamer, providing depth and smooth sustain.”
“The Hyde part is a heavier extremely versatile overdrive with more bottom. Use the Jekyll & Hyde pedal’s EQ to scoop out the midrange for a wide range of tones and a Sharp/Blunt switch to go from compressed to very bright. The sonic possibilities are endless.”
