Inspired by variations of the classic muff and the haunting and sustaining old growth Spruce forests of Norway, this fuzz is dynamic, heavy, and in your face. This silicon fuzz reacts to your guitar's tonal qualities and doesn't mask your base sound. Your Strat will sound like your Strat, and your Les Paul will sound like your Les Paul. Select "customized for bass" in the drop down if you want to use the Old Growth for bass. This option allows for more low-end response at higher Bark settings.
We always recommend isolated power supplies. If you daisy chain effects on one supply, you may inject noise, ripple, ground loop hum, etc. This effect requires 9v, center negative power. In other words, the industry standard power supply.
