Humbucker sized ‘P90’ single coil:
Though they are one of the oldest pickup designs around, P90s never seem to lose their appeal. However, it’s only in fairly recent years that the tone of a proper ‘90’ has been available in humbucker size.  
In the early days pickup winders fudged about using humbucker bobbins inside P90 style casings, or cut down P90 bobbins to fit ‘bucker’ sized covers.Unlike other companies we don't do fully nickel covered HB P90s, as our tests and research shows that a nickel cover is the only reason why a HB sized P90 could sound different to a traditional dog ear or soap bar P90. For us tone is everything.
 
Like the mighty ninety only more so! A 10k bridge, 8k neck powerhouse packing alnico 8 magnets. Harder rock tones and a powerful bass and midrange are the forte of the Critical Mass 90.
