Himmelstrutz Gramps

Modded slightly so the Treble/Presence pot is external (like the Gramps+), but you can always use an internal trimmer like the original if you prefer.  Sw1 in the layout is the "Temperament" switch in their info, the gain and sag switches are both internal jumpers in the original.  I'm not entirely sure how much difference the Sag switch will really make because all that does is put a 150R resistor in series with the supply.

Info about the original:

Jump on Gramps to daze and confuse. Which of course will make your band and audience gratefully amazed. Or use it on all guitar tracks on all your recordings for that not so shimmering, bowl movement provoking, beautiful sound.

Like the rest of the Himmelstrutz pedals Gramps will sound great at any volume. Just more crazy. And fuzzy. Of course it's also capable of generating lovely, magic distortion sounds which will transform your sleepy life into a creamy happy mess.
