Peavey Rage 158 Operating Guide

To set up your Peavey Rage 158, connect your guitar to the input jack using a standard 1/4-inch instrument cable. Plug the power cord into an electrical outlet and switch the amp on. Adjust the volume and tone controls to your preference.
First, check the power cable and ensure it's securely connected. Verify that the power outlet is functional. If the problem persists, inspect the fuse located next to the power cord on the amplifier's back panel. Replace the fuse if it’s blown.
Ensure all connections are secure and try different cables to rule out a faulty one. Keep the amplifier away from devices that emit electromagnetic interference. Adjust the equalizer settings and make use of the amp’s noise gate feature, if available.
Regularly check and clean the input and output jacks with contact cleaner to prevent corrosion. Keep the exterior dust-free and periodically inspect the power cable for damage. Store the amp in a dry environment to avoid moisture-related issues.
Yes, you can use effects pedals with your Peavey Rage 158. Connect your guitar to the input of the first pedal, then connect the output of the last pedal in the chain to the amplifier's input. This setup allows you to utilize external effects efficiently.
Turn off and unplug the amplifier before cleaning. Use a soft, damp cloth to gently wipe the control knobs. Avoid using harsh chemicals. If necessary, remove the knobs to clean underneath, but ensure they are reattached securely.
Set the amp to the clean channel. Adjust the volume to your preferred level. Set the bass and mid controls around the 12 o’clock position and the treble slightly higher for clarity. Fine-tune these settings as needed to suit your instrument and playing style.
Check if the distortion is due to high gain settings; try reducing the gain or switching to the clean channel. Inspect the guitar cable for wear and replace if necessary. Ensure that pickups and guitar output are functioning correctly.
The Peavey Rage 158 is designed primarily as a combo amp with an internal speaker. To connect external speakers, you would need a modification, which is not recommended. Consult a professional for advice on modifications.
Check all cable connections for secure attachment. Inspect the input jack for wear or damage. If using effects pedals, ensure their connections are also secure. If the issue persists, there may be an internal problem requiring professional repair.
