Using a stereo plug in a Mono amp

Hi all I bought an 1/8 inch stereo female to 1/4 inch stereo male adapter in order to plug my audio (computer and ipod) into a guitar amp via a 3ft 1/8 inch cable. What I'm wondering is: Since the amp is a mono jack, and I bought a stereo connecter, am I going to lose a channel of audio? ie. am I only going to hear stereo left playing through my amp? Or will the amp draw both channels though the top ring on the plug and play them in mono?? or do i need a stereo to mono connector for that? The guy at radio shack said I wouldn't lose a channel but I want to know what people think. Thanks.

Yes, correct ... you wont have any right channel, only left. You can buy an adapter plug that sums L and R internally. Rat Shack sells them, or atleast they used to. You may have to get creative with another adapter afterwards because I dont know if there is a 3.5mm stereo to mono plug/adapter that would also offer the female 1/4" jack, all in one. But then again, someone probably makes one.

  Many devices will not work properly if you parallel the two channels. This is what a two input one output adapter will do. With the two output devices in parallel they are trying to drive each other so they each need their own load. This is very easily accomplished by using a 100k ohm stereo volume control on the input of the amp. Each output device sees a load of 100k ohms and the two channels are summed from the wipers of the pot. RS sells a nice Alps 100k volume pot for a few bucks.
