So I'm about to lay down some cash on a new guitar. I've been eyeing this thing for a mad minute now. The thing is I'm a little concerned. I want to put some 11's on a C-1 Passive and change out the pickups to some Bare Knuckles. I'll probably go with Nailbomb in the bridge or the Cold sweat. Then maybe a duncan 59 in the neck or the neck version of the Nailbomb. I play in Drop C. The concerns I'm having are with the gauge and pickups as the title says. I'm worried the gap for the low E isn't going to be large enough for the 11's. Has anyone with a C-1 had an experience with this size string? Did you have to do any work on the nut? The next concern is the pickups. The c-1 has coil split. Is this going to be an issue? Also is the pickup slot large enough to fit the pickups without routing? I really would appreciate any and all help in the matter. I don't wanna throw down the cash and be stuck. I live in a small town and there isn't any decent guitar techs out here. So I'll have to do any work if needed.
