TUBE DRIVER RACK MOUNT
USER MANUAL
Congratulations on your purchase of the new TUBE DRIVER RACK Model #913. This
rack is an up-dated and more cost-effective design from the originator of the TUBE
DRIVER concept, B.K. Butler. We are confident this unit will be a welcome addition to
your tube sound.
TAKE TIME TO KNOW THE "RACK"
The rack is a very versatile unit. Please take the necessary time to look over this man-
ual and become familiar with the basic layout of controls as well as the unique fea-
tures. Take time and let your ears guide you through the tonal possibilities. The EQ
section has been carefully optimized for current and classic playing styles and has an
extremely wide range of control. It is possible that you may be just a tweak away from
your desired sound, so be patient and jot down the settings that you prefer most. Also
be aware of the range of uses this product was designed for... Everything from use as
an effects rack to that of a stand-alone pre-amp.
APPLICATIONS OVERVIEW
The TUBE DRIVER RACK is more versatile than one might expect at first glance.
While the basic design is an "effects" rack, it has several other functions as well. For
example, it can be used as a stand-alone pre-amp for basic power amps of any power.
The authentic “Tube” sound is thus produced at a SPL (Sound Pressure Level) poten-
tially exceeding any combo or stage amp made today! Another use finding great ap-
peal is the use of the unit "direct to the board" in recording work. The tremendous gain
potential within the unit, in addition to the exceptional output headroom, insure com-
patibility in a wide range of recording applications. There are, of course, the usual ef-
fects loop uses as well.
