9. MID (G30R only) - This tone control allows you to adjust the mid-range frequency
tone of your amp. The G Series tone controls use electronic circuits based around
those of the best sounding classic amplifiers. The normal MID tone (that is, flat
response) is when the knob is at the 12 o’clock (“5”) position. As it is turned clockwise
from the “5” position, the frequency area is boosted; as it is turned counterclockwise
from the “5” position, the frequency area is attenuated.
10. TREBLE
- This tone control allows you to adjust the high frequency tone of your amp.
The G Series tone controls use electronic circuits based around those of the best
sounding classic amplifiers. The normal TREBLE tone (that is, flat response) is when the
knob is at the 12 o’clock (“5”) position. As it is turned clockwise from the “5” position,
the frequency area is boosted; as it is turned counterclockwise from the “5” position,
the frequency area is attenuated.
11. REVERB (G15R and G30R only) – The control knob used to set the level of the internal
Spring Reverb.
12. CD IN - Your G Series amplifier features a CD input which you can use with a portable CD
player, cassette, mini disk or MP3 player. You can use the CD input to jam with pre-recorded
tracks or to learn a riff from a favorite recording.
13. PHONES - Connect any stereo headphone (600 ohms or less) to this standard 1/4" stereo
jack. When a plug is inserted into the headphone jack, the speaker output is disconnected,
allowing you to use your G Series as a practice amplifier. The level of the signal sent to the
headphones is determined by the setting of the Volume knob—at the point where a con-
nected speaker would clip, the headphones will clip.
WARNING: Because even the smallest G Series amplifier is capable of generating extremely
high headphone signal levels, always start with the Volume knob at minimum and then
slowly turn it up. In particular, a clicking sound is an indication of distortion and possible
damage to the headphones (and/or your hearing!); don’t let things get to that point!
14. POWER switch
- Use this to power the G Series on or off. When powered on, an LED inside
this switch is lit.
