The Rangemaster treble booster

The legendary Rangemaster effect. At the time, that is the end of the ’60s, the amplifiers are not prepared to distortion. I prefer to have a nice voice, faithfully reproduce the sound of the guitar. Of course, it was possible to overdrive when the guitar was full volume. If an external device,…

Hybrid Germanium Fuzz

You know the fuzz sound, but something is missing from it? Well, if something new or slightly different experience, these circuits can produce an alternative sound. This Hybrid Germanium Fuzz. Why Hybrid? It is combined with the old and new types of transistors. As the old germanium (AC128) in the…

Simple distortion effect with TL072

You need a new and simple Distortion effect? Really Simple? Look at this circuit: Not too demanding parts. But the voice .. hmm. Indeed, only a few spare parts required. The circuit is the “soul” of the tl072 chip. It is built around the circuit. And, of course, add garnish. Well,…

2n2222 Transistor inside

Daily barbarian act. What a bad 2n2222 transistor inside? Take a look at. This is a bad transistor:

LM386 Overdrive Effect

LM386 overdrive: easy, cheap, and fast to make. This is known and popular audio amplifier circuit with a fairly simple but good sounding overdrive guitar effect. Neither the operation of the complex. BS170 mosfet guitar signal to the already worsened. the R8 potentiometer regulates the amount of signal to the…

Peppermill guitar overdrive

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…

Muff Booster test

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…

High voltage tube guitar preamplifier with 12AX7

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…

Guitar Noise Gate

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.

Simple guitar vibrato effect

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.

PT2399 Basic delay

The well-known and used PT2399 effect chip. Sometimes it needs a basic echo effect in music. But especially on stage, concert essential supplies an echo pedal. Here is a simple basic circuit is shown. The circuit at Princeton Technology Corp. manufactures. Inexpensive, it can be used in many places. Datapage

High voltage DC to DC converter

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. The C3 capacitor…

Tone stack circuits

This is a tone collection of circuit, the most popular and most used circuits and offers some less well-known. Simple circuit, perhaps the most simple control circuit. Only two members. This uses the Valvecaster effect.

Low voltage tube preamplifier

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.

DC to DC converter

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…
