Audio Amplifier Gitar


Audio Ampifier Khusus Untuk Gitar

This is a circuit of an audio amplifier for the guitar. This circuit can reproduce a Combo amplifier of the type very common in the 'Sixties and the' Seventies of the past century. It is well suited as a guitar amplifier but it will do a good job with any kind of electronic musical instrument or microphone.
5W power output was a common feature of these widespread devices due to the general adoption of a class A single-tube output stage (see the Vox AC-4 model). Furthermore, nowadays we can do without the old-fashioned streetcars VIB-feature frequently included in those designs.
