I've been looking at bridges to replace my current Compton bridge. I love how it sounds, but I'm not a massive fan of how it looks. Online, I came by this bridge with a slightly arched metal base. Please tell me more about this thing, I bet you people know more. Haven't seen one like it before. EDIT: it also appears it has no string slots. Is it something you do yourself or are these just 'slotless'?
