Someone said M is Tremonti with a different magnet. I don't believe it personally, as IMO they are two completely different things sonically. M feels less gainy to Tremonti, it's WAY more articulated, and it sounds great, clean and overdriven. After I changed Tremonti Bridge / 59/09 Neck in my standard to square-bobbin Ms, the guitar woke up. I had it for sale, but now it's in frequent rotation. Give it a go, brotherI was actually watching a video of a guy comparing several different pickups. I was surprised at how good the \m/ sounded in comparison to the 57/08. I watched that particular section quite a few times. I had always thought the \m/ would be an aggressive, hot and just heavy pickup. Some what similar to the Tremonti that I am looking at replacing but it was actually way more versatile than I had initially thought. I do think the name and marketing on that one tends to make folks, like myself overlook it. Still looking forward to the 57/08, in the video I liked the way it sounded with big open chords a little bit more....time will tell.
