If the PAF Pro needed more harmonics and the Fred just didn't sound big enough for you then the Mo'Joe may be right up your alley! Named after the man who commissioned its design, Joe Satriani wanted a pickup in the voice of the Fred but run hotter and let's just say that for a middle class pickup the Mo'Joe runs HOT! It can easily drive pretty much any tube amplifier I played it through excluding my 70s Super Reverb and based on fundamental knowledge of Joe Satriani it was designed with rhythm playing in mind. Generally Satch while performing live will play the rhythm parts and the melody/refrain on the bridge pickup while switching to his neck pickup for fancier things so this pickup was just born to be muscled around. The notes you play are exposed entirely as what they are with little smoothness about the distortion in a lot of cases which to me has phenomenal places.. Think a modern version of Dean DeLeo's later distorted guitar tones. I've seen this pickup described as "growly" compared to the "searing" tone of the Freed. This pup doesnt growl, it snarls. Liken it to the vocal stylings of Megedeth's Dave Mustaine: loud, rude and probably never learned the meaning of the word Subtle. If you handle this quality wrong it becomes nasal and sometimes damn near unusable and this can be softened by using it in Basswood like Joe does. Personally I found it to be utterly pummeling in the bridge of a Mahogany Les Paul with harmonics for days and mids to cut through mixes easily. To repeat: I would not recommend this pickup for shred style leads or in situations where finesse and sustain are needed. It's much more of a muscle the hell out of it for tight, ballsy playing pickup.

In the first clip I am playing all the guitars on there with the Mo'Joe in the bridge and in the video any given dirty riff is being played with the Mo'Joe... I'm in front of the camera so it makes things a bit easier to tell.
For examples of this in Basswood I would cite Super Colossal, Professor Satchafunkilus and the Chickenfoot CD as it is still Joe's current Bridge Pup
