OWNER’S MANUAL  
We would like to take this opportunity to thank you for selecting a Crate product, and to tell you  
of our commitment to the design and manufacture of only the finest musical instrument amplifi-  
cation equipment; built for you, the musician.  
You have purchased one of the most innovative sound amplification devices available today.  
Your Crate amplifier gives you more performance features than ever before; features that you,  
the musician, have asked for.  
Your Crate amplifier is proudly Made in America. Only the finest available components and  
materials are used in the manufacture of each amplifier.  
All Crate amplifiers are subject to seven or more inspection and testing steps to assure you of  
a high quality product. The final test for each amp is conducted by a trained musician with the  
instrument the amp was designed for. Any unit that does not meet the standards of his discrim-  
inating ear will not be passed.  
Since all Crate products are designed, developed and manufactured through the cooperative  
efforts of engineers and professional musicians, the end result is a product that responds to the  
musician’s audio requirements, and a product that will serve your needs for years to come.

FRONT PANEL – INPUT  
SECTION  
CHANNEL A CONTROLS:  
7. VOLUME CONTROL: This control sets  
the overall listening level of Channel B.  
This control is independent of any set-  
ting made in Channel A.  
1. 0dB INPUT JACK: This input accepts a  
standard 1/4” phone plug and is suitable  
for any low to line level signal source  
such as an electric guitar.  
8. LOW CONTROL (Bass): The desired  
amount of “Bottom” or “Warmth” may be  
increased or decreased with this knob.  
2. -6dB INPUT JACK: This input jack also  
accepts a standard 1/4” jack but is  
padded 6 dB for hotter inputs such as  
tape decks or guitars with hot pickups. If  
both jacks are used, this input is not  
padded and will be equal to the 0 dB  
input jack.  
9. MID CONTROL (Mid): The tonal quali-  
ties of the midrange are very important  
to a good guitar sound. This knob can  
“thin-out” the sound when turned down,  
or “fatten-up the sound when larger  
amounts are used.  
CHANNEL A CONTROLS:  
3. GAIN CONTROL: This control sets the  
amount of gain for Channel A and is  
used to vary the amount of distortion.  
Minimal distortion is achieved with this  
control rotated counter-clockwise. A  
fully clockwise setting creates maximum  
distortion.  
10. HIGH CONTROL (Treble): This knob  
will affect the upper harmonic range of  
the guitar. Boosting it sharpens or adds  
crispness to the sound. For additional  
effect, use this control in conjunction  
with the Bright Switch (11).  
11. BRIGHT SWITCH: This switch affects  
the brilliance of the guitar’s sound by  
adding additional “bite” or sharpness.  
This switch affects both Channel A and  
B.  
4. LEVEL CONTROL: The overall volume  
of Channel A is controlled with this knob  
and should be used in conjunction with  
the Gain Control (3).  
5. SHAPE CONTROL: This is the overall  
tone control for Channel A. When  
turned to the left, a setting with heavy  
emphasis on mid range is achieved.  
When rotated to the right, the amp cre-  
ates a “fat” sound with extra boost on  
lows and highs.  
12. DEPTH CONTROL (REVERB): This  
control allows the player to alter the  
apparent acoustical qualities of a room.  
The sound can be altered from very  
“Flat” or “Dry” when the control is turned  
off, to that of a concert hall when used  
in larger amounts.  
6. CHANNEL SELECT SWITCH: This  
switch is used to select between  
Channel A and Channel B. When using  
the optional footswitch (23), this switch  
is inoperative.  
CHORUS SECTION  
13. CHORUS SWITCH: This switch turns  
on the stereo chorus when depressed.  
It must be in this position to enable the  
chorus footswitch (24).

19. ON/OFF SWITCH: This is a two-posi-  
tion switch; the down position will turn  
the unit on, while the up position will  
turn the unit off.

a line out (tip)/line in (ring) jack.
