11 BASS - This control provides approximately 15 db of cut or boost at 100 Hz, with a peak
(bell) curve. When the knob is at the 12 o'clock ("5") position, there is no boost or attenu-
ation (that is, flat response). 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.
12 MID - This control provides approximately 15 db of cut or boost at 2.5 kHz, with a peak
(bell) curve. When the knob is at the 12 o'clock ("5") position, there is no boost or attenu-
ation (that is, flat response). 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.
13 TREBLE - This peaking control provides approximately 15 db of cut or boost at 5 kHz. When
the knob is at the 12 o'clock ("5") position, there is no boost or attenuation (that is, flat
response). 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.
14 REVERB – The control knob used to set the level of the internal Spring Reverb.
15. CD IN - Your GT 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.
16. 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 GT60 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 GT 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!
POWER switch - Use this to power the GT Series on or off. When powered on, an LED
