1. Input: Connect your instrument here by means of a shielded signal cable. 2. Gain: Use this control to adjust the input gain. With the control towards the counter clockwise position, the gain is low and very little distortion is present. As you rotate the control clockwise the gain increases, producing more overdrive distortion and a higher output volume level. 3. Boost: This switch, when depressed, increases the output of the frequencies below 500Hz, giving the bottom end more punch. 4. Treble: Use this control to adjust the output level of the high frequencies. This control provides 8dB of cut or boost at 10kHz.
5. Mid: Use this control to adjust the output level of the middle frequencies. This control provides 9dB of cut or boost at 700Hz. 6. Bass: Use this control to adjust the output level of the low frequencies. This control provides 12dB of cut or boost at 60Hz. 7. Level: Use this control to adjust the output level of Channel B. 8. Reverb: Use this control to adjust the amount of reverberation applied to the signal. With the control fully counter clockwise no reverb is applied. As you rotate the control clockwise the reverb increases. 9. Lamp: This lamp illuminates when the amplifier is turned on. 10. On/Off Switch: Use this switch to turn the amplifier on and off.
