1.Input: Connect your instrument here by means of a shielded signal cable.
2.Clean Volume: Use this control to adjust the output level of the Clean Channel.
3.Clean/Overdrive: This switch, when de- pressed, selects the Overdrive Channel. When this switch is in the out position, the Clean Channel is selected.
4.Overdrive Gain: Use this control to adjust the gain of the Overdrive Channel. With the control towards the counter clock- wise position, the gain is low and very little distortion is present. As you rotate the con- trol clockwise the gain increases, produc- ing more overdrive distortion and a higher output volume level.
5.Treble: Use this control to adjust the out- put level of the high frequencies. This con- trol provides 12dB of cut or boost at 6kHz.
6.Boost: This switch, when depressed, increases the output by 10dB at 900Hz, giving the middle frequencies more punch.
7.Mid: Use this control to adjust the output level of the middle frequencies. This control provides 10dB of cut or boost at 1kHz.
8.Bass: Use this control to adjust the out- put level of the low frequencies. This con- trol provides 8dB of cut or boost at 150Hz.
9.Presence: This switch, when depressed, increases the output level of the high frequencies by 8dB at 10kHz, giv- ing a more “glassy” sound to the amplifier. This helps the output of the amplifier cut through “acoustically dead” rooms.
10.Overdrive Level: Use this control to adjust the output level of the Overdrive Channel.
11.Reverb: Use this control to adjust the amount of reverberation applied to the sig- nal. With the control fully counter clockwise no reverb is applied. As you rotate the con- trol clockwise the amount of reverb increas- es.
12.Lamp: This lamp illuminates when the amplifier is turned on.
13.On/Standby: Use this switch to acti- vate the amplifier. The On/Off switch (#14) should be turned on first. Allow 20 seconds for the amplifier to warm up before turning the Standby switch on.
14.On/Off: Use this switch to turn the amplifier on and off. This switch should be turned on at least 20 seconds before turn- ing the Standby switch (#13) on.
