stereo output > mono output

I've got a Yorkville acoustic guitar amp that has post fx outputs. One for R and one for L. I assume I can buy a Y cable that would take each separate output and combine them and run a cable that has a TS plug. The idea is to run this into a mono PA system as the main amplification and use the amp as a stage monitor. Is this commonly done? Will I lose any of the sound (other than the stereo image) just like you lose sound with phase problems?

Similarly, if I run the headphone output of a keyboard through the same cable described above, into a single channel to record with, will I lose any of the sound other than the stereo image?

I don't think you need to combine the L and R sides. Just use a regular TS cable for either R or L and you'll be fine.

won't that result in only the R or L signal going to the output? If the keyboard has stereo output, there must be different signals in each channel. Same thing with the chorus fx for a guitar amp.

1-You'll be losing the stereo effect anyway.

2-Combining both channels may not sound better than hearing only one channel.

Given the choice I'd take the single channel over a combination 90% of the time at least.


Edit: have you ever taken the time to actually listen to a single channel of a stereo KB? Don't knock it 'till you've tried it.

what about the chorus effect of a guitar? If I only use one channel, won't that effect disappear? But if I combine them, while I won't have the stereo image, I'll still hear chorus. And KB sometimes uses the stereo image for chorus fx, right?

The chorus effect is not inherently stereo. It is a short delay with modulation. Stereo chorus utilizes two channels to achieve a "wider" effect which is cool but irrelevant when played back through a mono source.

Really? I thought the signal was copied, delayed and then sent out to a second channel.

I guess I should just try and see what happens which I'll do later on tonight, hopefully.
