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 ...

Guitar Stompbox & Effects Projects
The classic Rangemaster is thought to have been the source of some of the best tones in rock guitar, from Clapton`s Beano sound to some of Brian May`s singing s...
Super Buffer for Guitars
There are situations in which very long cable runs are necessary from the pedalboard to the amplifier, or a more powerful driving circuit is needed to the heavy...
Guitar Effects & JFET Splitter
This is the schematic of a simple jfet buffer from the Basic Buffers article in the AMZ Lab Notebook, with the addition of pulldown resistors at the input and o...
Shruthi-1 Sound Filter
Incredible Shruthi-1 hardware synth with its excellent SMR-4 MkII filter board, both of which I built about a month ago and which I love to bits for exploring n...
MFOS Ten Step Analog Sequencer
This is an intermediate to advanced project and I do not recommend it as a first project if you are just getting started in synths or electronics. Only the circ...

MFOS NOISE TOASTER Lo-Fi Noise Box
The MFOS NOISE TOASTER circuit consists of seven main components: a voltage controlled oscillator, a white noise generator, a voltage controlled low pass filter...
Noise generator circuit
This circuit delivers a plentitude of noise, a veritable harvest of noise, yes, I dare say. an abundance of noise. Noise, noise and more noise. This circuit giv...
MFOS Micro-Sample & Hold circuit
Voltage to be sampled is applied to the input which is one end of R2 (100K linear taper potentiometer). The other end of R2 is grounded and thus the level of si...
Piezoelectric Sound
In contrast, a piezoelectric sounder (self drive type) consists of only a piezoelectric diaphragm with a feedback electrode. It is used in combination with an e...
