I made a small amplifier for the diddley bow, using a maplin amplifier kit [link], lunch box, speaker, switch, wire, soldering iron and solder. The kit from maplin arrives with good instructions, with a bit of time and after watching a few youtube videos on soldering all is complete and working.
Sounds pretty good and runs off a 9 volt battery.
Here is the improved electric diddly bow
It uses a baked bean can, piezo element (link), hot glue, 14” mono jack socket (link), guitar string, 2×4” CLS, bolt, tee nut x2 and a guitar string. Sounds great through a guitar amp.
This is a didley bow I made, this one is constructed with the following:
- scrap wood – approx 4×2”
- glass beer bottle
- scrap block of wood
- x2 screws
- copper wire or nylon fishing line
