Interesting Wiring Schematic
The pickups are connected to individual volume controls that feature push/pull functionality for coil tapping. They are routed to a 5-way switch before reaching the output jack. Additionally, a switch is desired to control the bridge pickup's activation when the...
Schematics 100W Power Amplifier for Guitar
This schematic is essential. Visit this page to find a comprehensive pre-amplifier and power amplifier design for your guitar, which includes a complete explanation of its operation and instructions on how to construct the enclosure.
The provided schematic outlines a pre-amplifier...
Fuzz Face
This is simple almost beyond belief for distortion devices. Two transistors, four resistors, three capacitors, and two controls make all that tone. The first transistor is set up with the simplest of arrangements - input through a DC blocking capacitor...
Guitar Tone Control
This preamplifier was designed as a stand-alone portable unit, useful to control the signals generated by guitar pick-ups, particularly the contact "bug" types applied to acoustic instruments. Obviously it can be used with any type of instrument and pick-up. It...
Guitar Vibrato circuit
The circuit of the unit is fairly simple, but is a bit irksome to set up. The reason is that obtaining matched FETs is not easy, so I had to make sure that the circuit would work with off-the-shelf FETs....
Final Project
The objective was to create an octave that could be played by pressing a crocodile paddle. This device was designed as an entertainment tool, functioning as a giant piano, allowing users to control sound with their feet. The project was...
4047/4066 audio slicer
You need to connect pins 1 and 13 of the 4053 to the virtual ground rail (top of C4), not the circuit's 0V rail.
The CD4053 is a triple 2-channel analog multiplexer/demultiplexer integrated circuit, widely used for routing analog signals...
Dodd Station
Dodd's 1909 receiver has survived and was discovered among various parts purchased at a yard sale. The components were identified from a photograph of the 1909 Station. Many of these parts were utilized in the construction of Dodd's 1912 station,...
Music Light Show
The circuit connects to the speaker outputs of your stereo or to the back of your speaker. The music passes through the transformer and the volume level is adjusted by the 5k ohm pot. Each light bulb is turned on...
