Why You Should Play Music in Stereo

Running in stereo gives your guitar a much bigger and 'wider' sound.
It makes it sound like your guitar is coming from everywhere and fills up the room.
Virtually all recorded guitar sounds are in stereo to give it a full "presence" and a bigger sound.
You can hear this effect when you listen to music on your headphones.
To run your guitar stereo in live situation you can do it a number of ways.
First, use a stereo amplifier such fender Princeton chorus or any digital modeling amp where "line 6" that is designated stereo.
Secondly, use a modern digital guitar processor.
Use any modern digital guitar processor.
These units generally have two outputs (left/right).
Then run two leads to two channels of a mixing desk or mixer/amp unit as long as the PA system is running in stereo.
This is very important.
Then you 'hard pan" each channel to each of the left and right outputs.
Some mixing boards have right and left stereo channels where you can put both outputs of your processor into one channel.
If you wish to hear your guitar separately from the other instruments, you will still need to "monitor" your sound through some type of amp that is not part of the PA system.
However, many bands these days choose to run everything into the PA system and have no stage amps at all.
Moreover, you can use two amplifiers and use one of the effect processors mentioned above or any effect unit such as chorus or delay unit that has two outputs.
One lead goes to one amp the other lead to the second amp.
This way you produce a stereo sound without using the PA system.
The down side of this is the set up is more time consuming, requires double rigging and twice as much actual equipment.
It is a lot of work, however, the result is remarkably different from playing through a single mono amplifier.
The sound quality is amazing and you get a stereo sound.
Most "intelligent" harmony machines or pitch shifters will only sound good in a stereo configuration when set up to do complex harmonies.
It's important that if you are going to use one of these instruments you set up a stereo speaker system to ensure quality sound control.
Do not be under the false impression that running two speaker cabinets out of two outputs of one amp is stereo, this is not stereo.
It is just adding another speaker to give extra spread of sound.
It does not add any actual power or create a stereo signal.
Stereo sound systems make your guitar sound better and fill the room.
It gives the listening a more complete music experience and should be used all the time.
