Fusing point to Fuzz box
ing, which is screwed into the furnace crown of a steam' boiler, and which melts when the level falls as low as that of the crown; this allows the escaping water and steam
to extinguish the fire. .

Fuzz Box. A special effects device, usually used with electric guitars, which creates a great amount of harmonic distortion. The "fuss" is the lack of clarity which results. Typically a fuzz box operates by overdriving a
preamplifier (toO much gain for the intended input signal) and then attenduating the preamplifier output so the signal level coming out of the fuzz box is not necessarily higher than the input level.
