Recording a mono guitar on a stereo track does not automatically make it wide. It often places the same signal on one side or duplicates it.
True stereo needs meaningful differences between left and right. A standard guitar pickup sends one mono signal. Stereo appears when two genuinely different channels are created by effects, separate microphones, dual amps or independent signal paths.
Mono source
One channel. A direct guitar or single amplifier microphone is mono.
Stereo effect
Ping-pong delay, stereo chorus or dual-cab processing creates two related but different channels.
Two identical channels are dual mono, not stereo information
Copying one mono signal to left and right makes it play from both speakers but does not create width. Stereo width requires differences in timing, frequency, level or content between the channels.
Double tracking
Two separate performances panned left and right create natural width.
Phase
Multiple signals can partially cancel when combined, so stereo rigs should be checked in mono.
Record the source in its natural format
One guitar input should normally be recorded to a mono track. Stereo effects can then be inserted after it, preserving simple routing and avoiding a file with sound only on one side.
Stereo can create phase problems in mono
Two wide channels may partially cancel when combined. Check stereo guitar effects in mono if the music will be heard through phones, small speakers or sound systems where the channels may not remain separate.
Set up the signal path
- Choose a mono input for direct guitar.
- Use stereo tracks only for stereo processors.
- Record real double tracks for width.
- Check the mix in mono.
- Record the dry guitar to a mono track and keep it centred.
- Add a stereo chorus or delay and listen to what changes between left and right.
When you hear noise, delay or no signal
A mono guitar is audible only in the left ear
The application is probably treating input 1 as the left half of a stereo pair. Select the mono version of input 1 or convert the track to mono.
Copied tracks sound louder but not wider
They are identical. Record a new performance or use a true stereo effect.
