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.
Basic circuit

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

Muff Booster test

The simple Muff Booster. This is a very simple circuit distorting project. Surely many people familiar with the legendary Electro Harminix from Big Muff guitar pedal. Many famous guitarists among almost as standard tools. this circuit, only a part of the original. One distortion segment. The electronic parts type of not sensitive, feel free to experiment with different types transistors and diodes, so a little bit different sound can be produced.

The diodes and transistor should be placed in a socket to be easily and quickly replaced. We tried out the following components: 2N2222, 2N5088, 2N3904, 2N2222, BC108 transistors and 1N914, 1N4148, red LED, 1N34 germanium diodes. The diodes to number want change , symmetrical, asymmetrical way to connect.
