GENERAL NOTES
Although the Rock is very ruggedly housed in heavy gauge steel,
care should be given to the unit as tubes are made from glass.
Avoid physical abuse. A soft touch to the footswitch is all that is
needed to switch the unit. You will notice the absence of a power
switch on the Rock. This was intentional on the part of the de-
signer. There is no possibility of unwanted power loss during a
performance, and power switches are just one more area of
eventual wear- out that has to be avoided. The Rock has been
designed for prolonged periods of continuous use without over-
heating or damage. It has been observed that the REAL TUBE
sound is actually enhanced with use as the tube ages.
