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?
By the way, phantom power is only needed for condenser microphones, which contain active circuitry. Electricity is fed through the mic to power the circuit. Since a Shure SM58 is a dynamic, you have absolutely nothing to worry about.
Thanks, all. I have one of those adapters--for some reason it works in my other amps but not this particular little odd-ball. A big part of my question had to do with... I just want to try it, you know, fun with solder!
