Pocket Sized Amplifier For Your Guitar.
Here is a guitar amplifier you can carry around in your pocket, yet whip out whenever you need it and put it right to work.
The amplifier is actually a miniature radio transmitter. The microphone on your guitar picks up the vibrations of the strings as you pluck out a tune, feeds it to the transmitter, which in turn sends the signal to any nearby AM radio which amplifies the signal just as it would any broadcast signal.
Three pages ( 2 sheets -front on first, front and back on second sheet ) B & W photos, illustrations, expanded views, materials/parts list and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
