There’s 2 settings, Hi and Low … Master Vol and Gain. There was a lot of experimenting with the clipping stage, the result is warm and vintage but also high output with a lot of cut. High gain setting is dialed in to be huge… big lows, open and almost blown out. No overly compressed shrill high end, none of that all or nothing gain setting.
Run it through some loud clean vintage amps and get dynamic distortion, harmonics, and big round tone response….or hit your dirty amp tone for a giant solo boost that sings. A full sweep of different dirt to get what you want out of your rig.
Like everything else from Daredevil, these are hand wired right here in Chicago, true bypass, take either 9V battery or external DC jack.
