1:INPUT: Connect your guitar here using a shielded instrument cable.

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

2:GAIN: This control sets the amount of com- pression and distortion from the amplifier. With the control towards far left, the sound will have a thick compressed quality. As you turn the control to the right 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 cre- ate a wide variety of sounds.

3:LEVEL: This control sets the output volume level from the Overdrive channel: in the far-left position there will be no output; as you turn the control to the right the output increases. Use this control along with the Gain control (#2) to create a wide variety of sounds.

4:OVERDRIVE SELECT: When this pushbutton switch is pressed in the Overdrive channel is engaged. The clean channel is selected when this switch is out.

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

5:LEVEL: This control sets the output volume level from the Clean channel: in the far-left posi- tion there will be no output; as you turn the con- trol to the right the output level increases. The far right setting is maximum output - as you increase the level, roll back the Low control (#6).

EQUALIZATION

6:LOW: Adjust the low frequency output level with this control: turning the control to the left reduces the low frequency output; turning it to the right 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, you may want to “roll off” the bass at high volumes.

7:MID: Adjust the mid frequency output level with this control: the center position is “flat” (no boost or cut). Turning the control to the left reduces the midrange output; turning it to the right increases the midrange output. The Mid control allows for 19dB of boost or cut at 900Hz.

8:HIGH: Adjust the high frequency output level with this control: in the center position the high frequency output will be “flat” (no boost or cut). Turning the control to the left reduces the high frequency output; turning it to the right increases the high frequency output. The High control allows a total range of 23dB of boost or cut at 5kHz.

9:REVERB: Adjust the amount of Reverb effect with this control: in its full-left position the signal will be “dry” (without any reverb). As you turn the control to the right the amount of reverberation increases.

10:CHORUS: The GX-25M features a built-in, preset Chorus effect to enhance the sound of either the Overdrive or the Clean channel. Press the Chorus switch IN to activate the effect.

11:HEADPHONES: For private practice ses- sions, plug a pair of stereo headphones into this jack. The internal speaker is disconnected when- ever headphones are being used.

12:EXTERNAL SPEAKER: You may connect the GX-25M to an external speaker with a rated impedance of at least 4 ohms using this jack. The internal speaker is disconnected whenever an external speaker is used.

WARNING: DO NOT attempt to use head- phones in the Speaker jack! Permanent hearing damage could result!

13:ON LED: The word “ON” will glow when you turn on the GX-25M, showing you that the ampli- fier is activated and ready to play.

14:POWER: This heavy-duty rocker-type switch is used to turn the amplifier ON in the left position, off in the right position. The ON LED (#13) works with this switch as a visual indicator.

15:POWER CORD: (Rear panel, not shown: This heavy-duty, grounded, three-wire power cord is to be plugged into ONLY a safely-wired, grounded 120 volt, 60 cycle AC power outlet. DO NOT attempt to defeat the ground connection of this cable!
