Well, again, we present a very simple circuit. As is also shown in the drawing, few parts. The circuit is based on a dual operational amplifier RC4558. But this is only half used, so there is only one using the op amp. Alternatively, you create an active tone control in the second operational amplifier section.
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, the sound midrange has been highlighted, they were given a musically useful sounds. At that same time, more “mid boost” existed. Among the most famous of all, to this day the “Dallas Rangemaster”. This is a very simple circuit using germanium transistor. The original device uses a OC44 transistor.
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 current one (2N3904) are made of silicon. So meet old and new technologies. The whole circuit is based on the old familiar fuzz circuit. These do not have to change much. But what if before the fuzz, coupled with a preamplifier? For example:
So, a pretty extreme sounds, or get extra distortion. Practically four parts and stronger, rougher sound is obtained. This small preamp, an existing Fuzz pedal built into it, such as tuning or mod. The options are:
Noise: Eliminate the high frequencies, less wheezing sound.
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, actually distort the character of the D1 – D4 diodes is given. In this case, two 1N4148 and two 1n914 diode. cut the signal. This results in a symmetrical but powerful cut. or maybe the solution according to their own ideas, but you can choose a sound character. even the parts is not too critical. I recommend them to feel free to experiment. Perhaps trying a different opamp is that it leads to what sound will surely hear some variation. the completed circuit can also change your tone of options. Examples: tone controls

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.
