"The ToneRite is used between playing sessions; simply plug it into a wall outlet. It fits between the strings of a steel-string, archtop, classical or acoustic bass guitar (up to 2-5/32" / 55mm string spread) and rests against the bridge. The special Elastone™ feet are designed to safely and quietly maximize energy transfer to the instrument. The intensity of vibration can be controlled by a convenient dial on the power cord. The manufacturer recommends an initial usage of 72 hours, with subsequent usages to maintain and further "open up" the response of the instrument.
110 volts AC, 60Hz.
Also available with international 220 volt 50 Hz. power adapter."
