Q: How can I reduce hum/noise/feedback when playing?
-Single coils pickups used with higher gain settings will often cause noise. Try combining two pickups via the pick-up selector or trying a different guitar to see if the situation is the same. Make sure all the input and output jacks are tight. Check the instrument with different pickup settings to make sure it is not a bad pickup connection.
-Higher gain settings tend to be the cause of many noise and feedback issues, try to dial the gain back on your amp a bit. Remember that heavy-rock bands often triple track (or more) when recording to create a thicker sound.
-Turn your volume knob off when you are not playing (even during stops in a song when possible).
-Turn off other volume controls not being used (i.e. volume trim pots)
-Use the highest quality cables you can afford, and the shortest distance you can live with. RF can create many noises that can be eliminated with well shielded cables.
-Experiment with distance and position between your guitar and amplifier/recording rig.
- Avoid florescent lighting when possible.
- Make sure that your instrument/rig is plugged into the same power source as the rest of your gear/band/PA system (to avoid ground loops).
- User a power conditioner/regulator to filter RF and keep the voltage constant.
- Experiment with the noise gate feature on your Line 6 unit or use an external noise gate.
Q: I hear a "popping" sound when I turn my amp on, is this normal? How do I reduce the popping sound I hear when I turn my amp on?
A: The popping sound is normal as it is a ramp of up the switch mode power supply. You can lessen the effect by:
i) not having the input plugged in (disengaging the preamp section).
ii) having the master volume turned all the way down (lowering the power amp output).
