From the post
I know there have been veros around for a while but I wanted to add this project to the main page.
It's basically a Rams Head Muff with an added Baxandall tone control.
You can find original FSB thread and schematic here.
It should easily fit it in 1590B size box.
Crank both treble and bass and you get a classic scooped midrange. Back both off, while turning up the volume knob and your midrange content increases. Park the treble and roll back the bass and the midrange scoop frequency shifts downward so you have complete control over which frequencies you are cutting. Roll the bass below noon and you start to add a bump to your midrange, which is great for running into a hot amp. This tone control style is capable of numerous sounds, making the Manx Loaghtan one of the most versatile pedals of this style.” - See more at:
