X-cabinet

Hmm. They say:

Capable of producing tones never before heard by mere mortals, this patented design will articulate every subtlety of your playing with exceptional speed, accuracy, and presence.   No more having notes bouncing around inside a box just to get trampled on by the next string attack.  This cabinet breathes them in and thrusts them out.  The efficiency of the X to convert amplifier signal into sound pressure is unmatched, and is one of the reasons we also call it the decapitator.

I say: Hmm.
