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. 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 Jack - 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 tremondous amounts of distortion to the signal for a harder edged "crunch" tone.

4. Channel 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 65 Hz. This will effect the low frequency signals. Turning it full clockwise, the signal is left alone. Turning it counterclockwise, the lows will be rolled off.

8. Preamp Switch - this switch selects which preamp style you are using. It will switch between the classic USA warm sound or Brighter sound famous in the UK.

9. Mid - this control is the midrange control. It is passive and set to shelve frequencies at 1KHz. This will effect the middle frequency signals. Turning it counterclockwise, your signal will "hollow out" the mids which is popular in today's music.

10. High - this control is the midrange control. It is passive and set to shelve frequencies at 5KHz. 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.

11. Digital Effects On/Off - this switch engages the digital effects section.

12. Effects Level - this control adds the digital effects section and mixes it into the main signal bus. Several different effects are available.

13. Program Select - this switch will select an of eight different effects. 2-Reverbs, 2- Delays, Chorus/Reverb, Flange/Reverb, and Tremolo.

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

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