Once again an interesting circuit. Okay, to combine it with a tube preamp and a fuzz face! What happens if a small powerful tube amplifier, and combined with the classic fuzz effect? What kind of sound will be the result?

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.
Matsumin wrote in his drawings Valve Caster 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 12AU7 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 12AU7s are just selected 12AU7s that have tested well at low voltages.
This circuit is a good example of the low voltage art!
Valve Caster tube effect circuit
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.

Real tube guitar distortion effects. unusual solution works of 2n7000 mosfet transistor. After the transistor is like the valve amplifier, it is very nice and pleasant natural sound of this effect provides a true analog distortion, no digital, no modeling!
Leave a CommentA lot of effects pedals has been prepared, including the famous Tube Screamer to mimic the old natural distortion of a tube amplifier. These pedals operate a semiconductor basis, more – less successfully mimic this sound. I did this and I use it with great joy:
New real tube distortion guitar effects. Mini tube amp, very full sound, beautiful tone.
With 12AX7 tube distortion pedal made.
Leave a CommentIn this article we take a closer look at a bit of a tube guitar amp ECC83 topic. Considering dual triode structure, which means that two of the same reinforcing element is a glass envelope closed. As will become apparent in the US or the Russian 12AX7 tube 6N2P (6Н2П) signal, which is not quite the same, but rather similar; here it is already different from the heater connection. Why is it so popular?
