We designed FRED to bump the mid-range of the PAF Pro EQ up a notch, but in the process something unusual happened. Harmonics that humbuckers usually don’t reproduce started popping out, particularly with overdriven amps and distortion units. FRED has about the same power as the PAF Pro, but the unusual overtones create a sound with more crank and growl. Joe Satriani was the first player to discover and exploit these qualities, and it’s been his main bridge pickup until the introduction of the Mo' Joe. FRED is really sensitive to changes in pick attack and control settings, and its distinctive tone makes a great recorded sound for both penetrating solos and tight rhythm tracks.
