Aural Exciter Makes Your Sounding Real

Aural Exciter since the 70’s. Do you know that feeling when you’re playing on guitar however you’re missing something? You’ve got many effect like distortion, overdrive, delay or something programed effect. You’re sure something is missing from your music and it’s not other than fatty and lively sounding. Fortunately there is a solution for this. It’s a very interesting device. It’s Aural Exciter or “harmonic enrichment”. This circuit adds harmonics sounds for the incoming signal. Aphex Electronics company made the first device in the 70’s. Initially it was made with vacuum tubes later with transistor. Nowadays you can get it…

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 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…

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 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. For more information, please visit the original site: http://www.runoffgroove.com/peppermill.html

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 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…

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 high voltage type! Min 250V.

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 30V. D1- D4 and C1-C5 voltage tripler circuit.  DC to DC converter is use in similar tube circuit.

3 Transistor Fuzz

Three transistor fuzz effect, strong sounding. Based on the famous Fuzz Face circuit, supplement with a preamplifier. Tried operating circuit! Q1 2N5088 pre-amplifier transistor can be replaced 2N2222, 2N3904, BC547 type. If you need tougher sound, the Germanium Fuzz Face for you.

The operational amplifier

  The operational amplifiers built a few dozen transistors attached to direct amplification circuits with high voltage. Often referred to as “op-amp”. Their properties vary widely depending on the model. Balanced inputs and outputs are usually asymmetric, high input resistance and very low output resistance. One of them is typical linearity and low cut-off frequency. According to their structure can be constructed of discrete components or integrated circuits. The operational amplifier are historical reasons for designation, since this type of circuit during WWII analog computer developed.
