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 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 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.
This BC547 transistors built a Low Frequency Oscillator, with LED indicator. Test video:
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. The prototype circuit:
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.
This is a Hybrid tube tremolo circuit. It is interesting that a low frequency oscillator (LFO) in electron tube is not resolved, we do circuit transistor for low frequency. BC547 transistors and used ECC82 or 12AU7, so the circuit operates at low voltage. Tube circuit provides classic, warm sine wave tremolo tones.
How to do it ribbon microphone? Here’s a quick and easy way of making the tape, microphone, a small electronics recycling and little need to add. Pictures of which draw on ideas:
Guitar boost effect circuit Here’s a simple guitar booster and distortion effect circuit. Since the ’60’s is used when the demand was bigger and stronger treble boost signal to the amplifier. From this period comes from the famous Dallas Rangemaster effects.
