GENERAL NOTES
Although the REAL TUBE 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 REAL TUBE.
This was intentional on the part of the designer. 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. REAL TUBE has been de-
signed for prolonged periods of continuous use without
overheating or damage. It has been observed that the
REAL TUBE sound is actually enhanced with use as the
tube ages.
