MODEL 301

 

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, the 

Rock 

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 
professional musicians the world over is yours with the 

Rock.

 

 

 

APPLICATIONS 

 

The Rock 

adds a second TUBE channel to any amp. Even small, inex-

pensive practice amps really sound great with the 

Rock. 

A Marshall ™ 

or other all tube amp sound unbelievable when hot-rodded with the 

Rock. 
 

Using the Rock — The E.Q. Section has been carefully tuned for to-
day's playing styles.  Full, rich overdrive distortion, yet clean enough to 
still hear chords somehow ... the 

Rock 

has it all. Start with the E.Q. 

Controls on "5" and the Slam and Scream set to 2 or 3. Then use your 
ears to set the quality of sound you're looking for, from current to clas-
sic: warm to scorching.  
 

The Tube — The 12AX7A tube in your 

Rock 

has been carefully tested with hu-

man ears for correct tonality 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 years. If replacement is necessary, contact our service outlet 
for information.
