1:INPUT: Connect your guitar here by means of a shielded instrument cable.

OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive.

2:GAIN: Use this control to adjust the amount of com- pression and distortion from the amplifier. With the con- trol fully counter clockwise, the sound will have a thick compressed quality. As you rotate the control clockwise the amount of distortion increases. Crate’s exclusive “Flex-Wave” circuitry uses sequential cascading gains to deliver distortion which is rich in harmonics and “touch sensitive.” Use this control along with the Level (#3) to create a wide variety of sounds.

3:LEVEL: Use this control to adjust the output volume level from the Overdrive channel: With the control fully counter clockwise there will be no output. As you rotate the control clockwise the output increases. Use this control along with the Gain control (#2) to create a wide variety of sounds.

4: OVERDRIVE SELECT: This switch, when depressed, activates the Overdrive channel. With this switch in the out position the Clean channel is activated.

CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds to medium distortion.

5:LEVEL: Use this control to asjust the output volume level from the Clean channel: with this control fully counter clockwise there will be no output. As you rotate this control clockwise the output level increases. For the best results, reduce the Low control (#6) when this con- trol is near the fully clockwise position.

EQUALIZATION

6:LOW: Use this control to adjust the low frequency output level. Rotating this control counter clockwise reduces the low frequency output, rotating it clockwise increases the low frequency output. The Low control allows a total range of 25dB of boost or cut at 80Hz. Due to the massive amount of low end available, this control should be reduced when playing at high volume levels.

7:MID: Use this control to adjust the mid frequency out- put level. Rotating this control counter clockwise reduces the mid frequency output, rotating it clockwise increases the mid frequency output. The Mid control allows for 19dB of boost or cut at 900Hz.

8:HIGH: Use this control to adjust the high frequency output level. Rotating this control counter clockwise reduces the high frequency output, rotating it clockwise increases the high frequency output. The High control allows a total range of 23dB of boost or cut at 5kHz.

9:DSP MODE: Use this control to select the digital effect. Each category and its central location is called out (delay, flange, etc.) by the markings around the control, with variations, as follows:

•Bypass (DSP off)

•Slapback delay

•Long delay w/regeneration

•Flange

•Slow Chorus

•Fast Chorus

•Chorus w/small room reverb

•Small room reverb

•Large room reverb

10:HEADPHONES: For private practice sessions, plug a pair of stereo headphones into this jack. The internal speaker is disconnected whenever headphones are being used.

11:EXTERNAL SPEAKER: Use this jack to connect the GFX-15 to an external speaker with a rated imped- ance of at least 4 ohms. The internal speaker is discon- nected whenever an external speaker is used.

WARNING: Do not use headphones in the Speaker jack. Serious hearing damage could occur!

12:ON LED: The on LED illuminates when the amplifi- er is on.

13:POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed).

14:POWER CORD (rear panel, not shown): This grounded power cord is to be plugged into a ground- ed power outlet, wired to current electric codes and compatible with voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection.
