We like to test the effects of different circuits, in addition to its own development. So we found a simple, few parts built in guitar Overdrive circuit. The first stage is a 2N7000 or BS170 MOSFET, J201 JFET the second circuit. The J201 Drain voltage is 4.5V. The R9 potentiometer to adjust. Variations may be a little higher voltage softer, low voltage rought the voice.

Some portions of the circuit is different from the original. Example C1, C2, C3 capacitor value. But that does not noticeably affect the sound.

The simple Muff Booster. This is a very simple circuit distorting project. Surely many people familiar with the legendary Electro Harminix from Big Muff guitar pedal. Many famous guitarists among almost as standard tools. this circuit, only a part of the original. One distortion segment. The electronic parts type of not sensitive, feel free to experiment with different types transistors and diodes, so a little bit different sound can be produced.
The diodes and transistor should be placed in a socket to be easily and quickly replaced. We tried out the following components: 2N2222, 2N5088, 2N3904, 2N2222, BC108 transistors and 1N914, 1N4148, red LED, 1N34 germanium diodes. The diodes to number want change , symmetrical, asymmetrical way to connect.
The high voltage tube guitar preamplifier project is an adaptation of the famous tube preamplifier to suit the DIY’ers demands. Searching the net, I’ve never come across similar idea, so I decided to share this version of our very popular design. This a classic, conservative design, that easily matches other musical devices.
The preamp contains one channels of real-tube, high-gain circuit. This circuit uses JJ ECC83 (12AX7) tubes. Circuit uses a stabilized 12V DC voltage.
While playing the guitar many times there is a problem that unwanted noise can appear. Hence the need for a guitar noise gate. It happened specifically to a high-gain circuit is very sensitive to the surrounding radio signal.
This is a simple guitar vibrato effect, used to obtain the variation in pitch. The circuit of is fairly simple.
The oscillator is a standard transistor circuit, and has been used for this sort of application many times.
This is a simple 555-based high voltage inverter circuit. The high voltage DC to DC converter is suitable for small current (a few mA) but requiring high voltage electronics. For example Nixiu display, VFD, or a other vacuum tube circuit. We will use a tube guitar pre-amplifier.
It is a low voltage tube preamplifier, specifically guitar preamp. Uses 12AX7 or ECC83 tube. No complicated circuit. The circuit is similar to the famous old guitar amplifiers bright channel. Low voltage operation, does not require a separate anode and output transformer.
This circuit is the old and well-known NE555 integrated circuits based. DC to DC circuit is not complicated, little parts, and doing pretty much stable voltage. It produces with the 12V DC voltage of 30V to voltage. The NE555 constant operating frequency is set. The 3 pin voltage convert of 30V. D1- D4 and C1-C5 voltage tripler circuit. DC to DC converter is use in similar tube circuit.
Recently I found this interesting distortion fuzz circuit with 2n3904 transistors. The Howie’s Metal Simplex. I immediately liked, to build and testing. This is a silicon fuzz circuit. Interesting solution uses LED signal cut, although similar topology as old Fuzz Face.
This is an inverting op amp circuit. Proven operating op amp circuit that uses the old and popular LM741 (at Texas Instruments products, datapage ) circuit. Op amp inverting amplifier circuit is very simple, some spare part.
