Description

Edit description

After a year of development, testing every transistor obtainable and painstakingly listening to every component available for this pedal… the Third Stone was born. The key to the tone of the pedal is the natural mid-range, control over the bass, and the incredible feel. The mid-range will cut through better in a live performance. Inspired by the Fuzz tones of the 1960’s the Third Stone was designed to be the most organic and versatile fuzz made.

Doyle Bramhall II demonstrated the Berkos FX Third Stone fuzz pedal for John Bollinger in the January 10th, 2017 issue of Premier Guitar’s Rig Rundown.

In walking through his rig, Doyle takes the time to discuss the Third Stone, stating: “This is a Third Stone which is made by Berkos FX. And he usually takes a lot of the Germanium Parts and makes Dallas Arbiter fuzzes and this, which is more like the later Jimmy fuzz. Like Woodstock fuzz.”
