REAL TUBE
Congratulations on your purchase of the best TUBE
floor- mounted overdrive/preamp on the market. While
virtually all other overdrive and simulated tube effects
today rely upon cheap solid-state components for their
bogus, imitated tube sound, REAL TUBE delivers what
the name implies - real tube sound from the classic
12AX7A twin triode tube! All the warmth and tonality
that have made tube amps the #1 choice of profes-
sional musicians the world over is yours with the REAL
TUBE.
APPLICATIONS-REAL TUBE adds a second TUBE
channel to any amp. Even small, inexpensive practice
amps really sound great with REAL TUBE. A Marshall
or other all tube amp sound unbelievable when hot-
rodded with a REAL TUBE.
USING REAL TUBE-The E.Q. Section has been care-
fully tuned for today's playing styles. Full, rich overdrive
distortion, yet clean enough to still hear chords some-
how ... REAL TUBE has it all. Start with the E.Q. Con-
trols on “5” and the Drive and Output set to 2 or 3.
Then use your ears to set the quality of sound you're
looking for, from current to classic: warm to scorching.
THE TUBE-The 12AX7A tube in your REAL TUBE has
been carefully tested with human ears for correct tonal-
ity and absence of microphonics, noise, etc. It is NOT
advisable to change this tube with available up-graded
tubes as the normal life expectancy is 2-4 4 years. If
replacement is necessary, contact our service outlet
(listed on the last page of this brochure) for informa-
tion.
