The Headphone Amplifier is just that – an amplifier for using headphones while playing guitar. This version features a gain trimmer to dial in a good clean signal, and an output volume knob to keep your ears from bleeding. Check out the Testing Rig if you’d consider using one of these in conjunction with a tiny-tester to create a low volume device for testing, trouble shooting, and designing guitar effects PCBs.
