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:

Hybrid Germanium fuzz basic circuit. Use NOS germanium transistors.

So, a pretty extreme sounds, or get extra distortion. Practically four parts and stronger, rougher sound is obtained. This small preamp, an existing Fuzz pedal built into it, such as tuning or mod. The options are:

Noise: Eliminate the high frequencies, less wheezing sound.
Volume: Output level
Fuzz: The amount of distortion
Compression: Stronger or softer fuzz effect

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.

Valve Caster tube effect

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!

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.
