Haven't used pedals other than tuner & muff before and I could use the benefit of some collective TB experience. I'm just gonna list the pedals I'm assembling onto a board powered by a One Spot, and you tell me the order in which they belong: Boss tuner - obviously 1st Big Muff Deluxe Diamond Bass Comp Jr. Donner Octaver MXR M81 preamp Broughton HPF (on it's way from Canada) Are there different sequences for different purposes, or is it a hard & fast order? I've searched (cursorily) and found conflicting answers. I expect to get a few conflicting answers here but at least they'll be from guys who have real-world experience doing what I do. Thanks! I'll post pics when I get it sorted out.
