right increases the midrange output. The Mid control allows for 19dB of boost or cut at 900Hz.

9: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.

10: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.

11:CHORUS ON: To activate the Chorus effect, press this switch in. (This switch is disabled when a footswitch is plugged in – see #14)

12:DEPTH: Adjust the overall amount of chorus with this control: to the left for slow, smooth “phasing” sounds, to the right for faster “vibrato” sounds.

13:RATE: Adjust the speed of the chorus effect with this control: to the left for a little effect, to the right for a lot.

14:FOOTSWITCH: Plug a dual footswitch (such as the Crate CFP-2) here to control channel selection and chorus on/off. (Tip = channels, ring =

chorus, sleeve = ground.)

15:HEADPHONES: For private prac- tice sessions, plug a pair of stereo headphones into this jack. The inter- nal speaker is disconnected whenev- er headphones are being used.

16:EXTERNAL SPEAKER: You may connect the GX-40M 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!

17:ON LED: The word “ON” will glow when you turn on the GX-40M, show- ing you that the amplifier is activated and ready to play.

18:POWER: This heavy-duty rocker- type switch is used to turn the amplifi- er ON in the up position, off in the down position. The ON LED (#17) works with this switch as a visual indi- cator.

19: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!
