Some pictures: electronics repair. The product name: Dynacord Eminent II. This is beginning to be manufactured in the mid sixties. Initially, all tube design, and later the transistor preamp and tone section. Meanwhile, little change in design as well. This … Continue reading →
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 … Continue reading →
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 … Continue reading →
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. … Continue reading →
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.
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 … Continue reading →
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 … Continue reading →
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.
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 … Continue reading →
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 … Continue reading →
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. The prototype … Continue reading →
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 … Continue reading →
