Hey Y'all,
I am planning to make a Dual pedal using the Gruntbox/Faultline and Yellow Shark and was looking for some tips to make the Yellow Shark work better for bass. I've heard rumors that the BJFE Blueberry Bass OD was just this pedal but with a few minor changes. Thanks for the help in advance.
I would try either increasing C12 from 4n7 to 47n or remove it altogether. That should let a lot more of the bass frequencies pass through to the output.
