I forgot. Does the GS100 have a mic socket?

It has a multi-purpose socket that will accept the supplied zoom controller/mic combo or just a standard 1/8" mini plug mic.

Thanks. That's what I thought but forgot. (Old age.)

Just a quick question, When you plug in the standard 1/8 mini mic plug into the mic input will that turn the external mic off?

will that turn the external mic off?

You mean the internal mic, right?

The answer is yes that once a mic is plugged in the the internal mic is disabled.

Yes, the internal mic. Thanks Tommy, That helps a lot!
