    phase cancellation means that when two sounds of the same frequency and opposite phase (meaning that when one sound wave is at a peak, the other is at a "valley" or low point) are mixed together, they cancel each other out, and you hear nothing.

    this is an oversimplified explanation - in the real world only certain frequencies would cancel, others would actually be amplified louder, since every note you play is a combination of distinct frequencies. often times this happens when multiple mics are recording the same sound source, the lower frequencies will cancel somewhat and it will cause the tone to get thinner.

    i don't see why a bbe sonic max would do anything for phase issues, but i don't know.

    Phase cancellations is usually fixed on some sort of mixing console, be it live or in a recording studio. The BBE is not quite what you are looking for.

    Why do you ask? If you can describe a problem you're having maybe we can help out a little bit more.

    ok, i know what you mean. this might not be it, but on my bass the 3rd fret of E string is very low in volume compared to a harmonic-rich note like the 7th of E string. Its not wear down of the frets, and I pluck it with the same strength, it just seems not to be sounding right. Maybe its the guitar, or amp? whats going on?
