From the vendor
Stone Grey Distortion is a responsive and modern high-gain distortion designed for guitarists who really need a lot of gain.
Many guitarists are looking for the same evil distortion in which you can twist all the knobs to the right and at the same time get a readable sound, not a mess! Masters from Mad Professor managed to achieve this effect. The pedal is perfect for all metalists of the "new school" with 7-8 strings. You can be sure that each string will sound clearly and will not be lost in the mix!
Turn the knobs as you like and get a good sound. Now you can not be afraid of experiments. And if you want to play rock in the spirit of Deep Purple, Led Zeppelin, then put the handle up to 12 hours, and a pleasant crunchy overdrive / crunch is provided to you.
The pedal has a lot of potential, and it will never get lost in the pedalboard of both the blues-rock guitarist and real thrash metalists.
