Pedal description

This mini guitar amplifier delivers ½ Watt at 9V, being perfect as a home practice amp. It has gain and volume control, offering a very dynamic sound on any speaker.

This amplifier is based on the circuit of the Ruby Amp (runoffgroove.com), a reference DIY project with a lot of documentation in multiple DIY forums. You can also modify the components and use the PCB to design your own amp circuit.

The PCB allows to install a led (with its resistor) and a switch for extra gain. The potentiometers can be directly mounted on the PCB.
