Free The Tone Introduces the Red Jasper Overdrive

The Red Jasper is a low gain overdrive pedal that’s driven by the player’s emotions.
Smooth highs, punchy mids, full but tight lows, sensitive, responsive, natural and pleasing compression feel. Free The Tone’s first low gain overdrive pedal “Red Jasper” has been designed to obtain these magical attributes that only superb vintage tube amps can usually produce.

The Red Jasper amplifies the guitar’s original sound faithfully, adopting a passive type tone circuit to minimize phase errors in the guitar signal and obtain a natural tone. With first priority placed on sound, a slightly larger die-cast case is adopted.
