1) CD/Tape Input - this 1/4" 3 conductor jack will allow you to plug in a CD player, tape or any other source to practice along with. It sums the left and right signals into a mono signal and passes it through to the amplifier section. To control the volume of the source, adjust the output volume of the device. We suggest you turn the volume all the way down then plug in and adjust the volume according to your taste.

2) Guitar Input - this is a 1/4" 2 conductor input jack for plugging in your instrument. It is intended for guitars but will accept other instruments as well.

3) Lead Gain - adjust this clockwise to increase the amount of distortion you add to the overdrive signal. Used in the lower ranges of the control, you get a less distorted sound, a "bluesy" tone. As you increase the gain, you add tremendous amounts of distortion to the signal for a harder edged "crunch" tone.

4) Channel Select Switch - this switch selects which preamp you are using. It will switch between the Rhythm and Lead channels.

5) Lead Volume - this control is the output volume control for the Lead Channel. It follows the same tone circuit as the other channel. It's gain structure is determined by the lead gain control but this serves as the overall master volume for this channel.

6) Rhythm Level - this is the volume control for the clean channel. It's gain structure is preset for maximum signal before distortion and determines the output level of the amp.

7) Bass - this control is the bass control. It is passive and set to shelve frequencies at 100 Hz. This will effect the low frequency signals. Turning it fully clockwise, the signal is left alone. Turning it counterclockwise, the lows will be rolled off.

8) Mid - this control is the midrange control. It is passive and set to shelve frequencies at 700 Hz. This will effect the middle frequency signals. Turning it counterclockwise, your signal will "hollow out" the mids which is popular in today's music.

9) High - this control is the high control. It is passive and set to shelve frequencies at 4KHz. This will effect the high frequency signals. Turning it fully clockwise, the signal is left alone. Turning it counterclockwise, the highs will be rolled off.

10) Headphone Jack - this is a 1/4" 3 conductor jack for plugging headphones. It will sum the signal and put the sound in both ears, thereby creating a pseudo-stereo sound. Volume will be
determined by the volume control on the channel you are on. It will disconnect the internal
speaker when plugged into. This will allow quiet practicing.

11) Jewel Light - this jewel light lets you know that the amplifier is on.

12) Power - this switch turns on and off the AC power to the amp.
