I have a cute little 25 watt amp that looks like it was designed in the early 70s ("all transistor!!"), nice aqua/silver speaker cloth over a 10" speaker. I want to set it up so that someone could plug an iPod in and sing along, or sing and play guitar.
The amp has 3- 1/4" phono input jacks, one off/on/volume and one tone control.
I would like to reconfigure it just slightly by changing one of the input jacks to a 1/8" mini phono, which I don't believe presents any problems, and by changing one of the other two to an XLR (microphone) input.
Will this work? Can I just swap it out? I don't know much about electronics. I have heard the term "phantom power" in re: microphones, but I don't really know what it means or how it works. Does a microphone like a Shure SM58 have enough output?
If changing a 1/4" phono input jack to an XLR input jack is NOT a simple one for one, then is there something else that could be done to make it work?
