Control signal Automatic Fader by LF351

This be Control signal Automatic Fader circuit , help fine decorate or control sound signal tallly or low follow want. In model the automatic convenient for the system electricity guitar , side sound of music work. By this circuit uses FET , then have tall rapidity , there is the crazy low and use IC op-amp model FET , number LF351. Then have disturb lower. The S1 for fine the pitch High or Low get, and have fining decorates the pitch done to a turn VR1,VR2 you can the detail adds in the circuit.

Control sound automatic by BC109

This circuit is the sound controls automatic circuit, by it will fix to don’t give popularity level in the sound doesn’t expire. When feed sound signal reaches in this circuit , as a result , will have a signal, will the power goes up to flow through LED shine to LDR. The connection and a resister have a side input ,make control popularity level in the sound that a side output get , when see the circuit has already. I uses important equipment , be the transistor number BC109 and other equipment a little again. By you can fix signal sound level can control with VR1 with try fine can decorate follow want.

Fuzz box by all FET

All-FET design
Valve-like distortion behavior

This circuit was designed to obtain a valve-like distorted sound from an electric guitar or other musical instrument.
For this purpose a very high gain, three-FET amplifier 2N3819 circuit, was used. The output square wave shows marked rounded corners, typical of valve-circuits when driven into saturation.
Therefore, the distorted sound obtained from such a device has a peculiar tone, much loved by most leading guitarists.
