That’s what it’s there for. To make it sound right with other pedals. You added a big buffer circuit with the Canyon, that’s why it sounds fine now that you’ve turned the SF buffer off. That’s why some people run their tuner in-line with other pedals, espescially if most of them are true-bypass, because it adds a buffer circuit. Or you’ll see guys who run a wah before their fuzz face put a tubescreamer or super over drive between the wah and fuzz. It adds a buffer circuit and keeps the fuzz from going into melt-down with the wah (which sounds awesome btw).
This is not a rhetorical question.
What about the ever-elusive battery door for the big box pedals like the Big Muff and Small Stone?
Where can I find those?
