Little Gem Guitar Amp Questions Answered
I recently went to build the Little Gem guitar amp from runoffgroove.com. Its a great little amp from what i have read. I made the basic heart of it so far. I have the four caps, resistor, IC socket, and its all connected. I think basically all thats on the breadboard for the PCB layout here: http://runoffgroove.com/littlegem.html(scroll down).
I'm confused on where to put the two pots and connect power and all that. I don't have the gain pot yet, but i do have the 25 ohm rheostat. The rheostat has three prongs, would i use the middle leg for the "out" part and the other two for the other part? I can't seem to get it.
Also, is there a common ground between the input from the guitar, the 9v battery, volume pot, and output?
I found a layout on Flickr that explains it, i think. See the third picture.
