DIY PAM8403-based cheap guitar headphone/pre-amplifier (<10€):
![Guitar headphone/pre-amplifier](./portfolio/guitar_preamp.jpg)
- mini stereo "3W" amplifier circuit board (<1€)
- vol+sw knob (<1€)
- 2x guitar jacks (<2€)
- headphone jack (<1€)
- 2x AA battery holder (<1€)
- altoids or a match box
- the input ground is NOT the same as the output's - you MUST isolate jacks from chassis;
- put a load resistor at the outputs, never leave an output unconnected;
- you may want to place a resistor in series with the headphones jack as it gets loud very quickly!
