I have 2 guitars with P90s and am considering swopping out the P90s in one of them for some mini hums. Not at all sure about this yet, but I am interested in suggestions for some good mini hums. I don't want to route the guitar at all and would be looking for drop in replacements. I love both of the guitars, but I don't really need both of them. Both are P90s, trem, one with black limba and one is mahogany. So, I am considering changing one of them or selling one. Just looking for ideas. Thanks. Evan.
