Octaver-Fuzz Guitar Effects
This is the circuit diagram of Octaver-Fuzz Guitar Effects Unit that easy to. Above schematic diagram was extracted from ETI-Canada, January 1980. The transistor Q1 is MPS6515, The diode DI and D2 are 1N4148. The IC is any low noise dual op-amp, shown on above scheme is the 4558. Switching could be improved with a full bypass mod. (more…)

Multidirectional microphone amplifier

Multidirectional microphone amplifier
This Multidirectional microphone amplifier circuit is often used in a panel discussion or a meeting room to capture the audio from all the partners without the need to give each microphone. Placing this in the middle of the table captures audio from each through which is formed by four electret capsules with a level control for each individual reception. (more…)
