4. Controls and Functions
Familiarize yourself with the front panel controls of your Peavey Backstage amplifier:

This image displays the front panel of the Peavey Backstage Guitar Combo Amp. Visible elements include the input jack, 'LEAD' channel controls (Overdrive, Volume), 'EQ' controls (High, Low), 'TAPE/CD' input, 'HEADPHONES' output, and the 'POWER' switch. The speaker grille covers the lower portion of the amplifier.
- INPUT: Connect your guitar here using a standard 1/4-inch instrument cable.
- LEAD Channel:
- OVERDRIVE: Controls the amount of gain and distortion in the Lead channel. Turn clockwise for more distortion.
- OFF/ON Switch: Toggles between the Clean and Lead (overdrive) channels.
- VOLUME: Adjusts the overall output level of the amplifier when the Lead channel is active.
- EQ (Equalization):
- HIGH: Adjusts the treble frequencies for brightness.
- LOW: Adjusts the bass frequencies for depth.
- TAPE/CD: A stereo input jack (3.5mm) for connecting external audio sources like an MP3 player or CD player, allowing you to play along with backing tracks.
- HEADPHONES: A stereo output jack (3.5mm) for connecting headphones. Plugging in headphones will mute the amplifier's speaker, enabling silent practice.
- POWER Switch: Turns the amplifier on or off. The red indicator light illuminates when the amplifier is powered on.
5. Setup
- Placement: Position the amplifier on a stable, flat surface. Ensure adequate ventilation around the unit.
- Power Connection: Ensure the POWER switch is in the OFF position. Connect the amplifier's power cord to a grounded electrical outlet.
- Guitar Connection: Connect your electric guitar to the INPUT jack using a high-quality 1/4-inch instrument cable.
- External Audio (Optional): If desired, connect an MP3 player or other audio source to the TAPE/CD input using a 3.5mm stereo cable.
- Headphones (Optional): For silent practice, connect headphones to the HEADPHONES output.
6. Operating Instructions
- Power On: Turn the POWER switch to the ON position. The red indicator light will illuminate.
- Initial Settings: Start with the VOLUME and OVERDRIVE controls set to their minimum positions (fully counter-clockwise). Set the HIGH and LOW EQ controls to the middle (5) position.
- Clean Channel: Ensure the OFF/ON switch for the LEAD channel is in the OFF position. Slowly increase the VOLUME control to your desired listening level. Adjust the HIGH and LOW EQ controls to shape your clean tone.
- Lead (Overdrive) Channel: To engage the overdrive, flip the OFF/ON switch to the ON position. Slowly increase the OVERDRIVE control to achieve the desired amount of distortion. Adjust the VOLUME control for the overall output level of the Lead channel. Use the HIGH and LOW EQ controls to fine-tune the overdriven tone.
- Playing with External Audio: If an external audio source is connected to the TAPE/CD input, its volume will be controlled by the external device itself. The amplifier's volume controls will only affect your guitar signal.
- Silent Practice: When headphones are plugged into the HEADPHONES jack, the main speaker will be muted, allowing for private practice.
- Power Off: When finished, turn the POWER switch to the OFF position.
