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.

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.

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.

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 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.

Matsumin wrote in his drawings ValveCaster 2007, the goal was to create a real tube boost / overdrive pedal that can run on a single 9-volt battery. It worked! Unfortunately defecate 9V battery snap. Valvecaster run well in a 9 or 12-volt power supply. 12V will give you more headroom and cleaner sound. It is designed with single coil pickups. A 12AU7 is particularly suited to this, by virtue of being virtually identical to a 12U7 which was designed to be used at low voltages in old car radio circuits. Indeed some sources say that there isn’t really a difference between the two types and that 12U7s are just selected 12AU7s that have tested well at low voltages.
This circuit is a good example of the low voltage art!

This one is a pretty popular now overdrive the real tube. Very nice real tube amplifier has a voice, booster little overdrive sound. Many people rely on this effect. The circuit is quite simple, and best of all the ECC82 or 12AU7 tube operating voltage of 9-12. So many people are doing it from the circuit custom guitar pedal. It has a place among boutique guitar pedals. few circuit modifications everyone can find their sound. The design tube made with the point-to-point wiring. TONE potentiometer and capacitor (R6, C4) is a passive filter. The device structure is simple, the ECC82 dual triode circuit of the soul. This tube is designed to drive the tube is thus relatively little strengthening. but larger current running as the rest of the series (ECC83, ECC81, ECC85), and this is associated with low voltage. ECC82 only the electron tube may be, or of the same type, so 12AU7, 5814 etc vacuum tube. Interestingly enough ECC85 tube works well.

1 Basic chromatic tuner, it is sure to be. If you do not want to misrepresent your favorite songs play.
2 Of the noise-canceling, verily, it happens that the environment is so noisy that the guitar voice is not exactly play lyrical melodies.
3 Ibanez tube screamer basic series and its clones, bigmuff, Overdrive and Distortion (usually Boss) and Fuzz.
4 Echo, reverb, effects, these never enough to be a soft melody than for dramatic effect or even be stronger crushing.
5 Phase shifter, roll your guitar signal, whether dizziness.
6 Expensive and exotic, such as Klone Centaur (this is what is analyzed), Landgraff, Keely and boutique / modified pedals are very expensive, interesting exterior and sound, and the original 30 to 40-year-old pedals.
7 Graphic equalizer, is essential if the guitar has not “crying” you will now!
8 Tremolo to be a titillating “surge” in music.
9 Wah, it should. foot play guitar tone, too!
10 “Do not know what it is, but it sounds good” pedal, so worn or special that can not be determined what, but the sound of “oooh I must”, of course if you ask a guitarist, “what is” not to tell, and mysteriously smiling.
+1
Multi-effects,
Usually starting band. million crammed into effect, a plastic awful sound. Brrrrrr…The devil himself.
And what effects you use? Write it to me !

We have built and tested in this great sounding guitar overdrive circuit.
Shaka HV overdrive schematic
“The shaka hv (higher voltage) is a very low to medium overdrive pedal. This pedal can give you very good clean
boost as well as very low to medium overdrive. To get 18 volts from two batteries, connect the negative of a battery
clip to the positive of the other battery clip. Now use the two remaining leads as usual wich will give you 18 volts.
All caps are film type except the electrolytics. Be sure to use at capacitors that can handle at least 18 volts rating.
The FET is a J201 and the op amp is a TI RC4558 dual op amp. You can use a TL071 single op amp as well. This circuit
uses various snippets from Jack Orman who has don great work with Fets in distortion circuits.
Note: You can also put a capacitor 10uF to 47uF in value from 18V to ground.”
We test op amp and dual use JRC4558 and Fairchild FET J201. The circuit is the same as Klon Centaur, it also uses a high voltage (18V) sound production.
