Germanium mod download

Sounds really good. I'm don't really know a lot about doing mods myself. Is it possible to apply any of these or other mods to a little big muff? That is a great idea. I think I will make a "full mod" Big Muff one day to show all the possibilities. I have a Russian Black Pi, wanting to install a Boss style plug so I can stop changing the batteries all the time. I saw where. It said this unit is somewhat rare Should I just leave it alone, or will it decrease the value if I modify it in this fashion?

Everyone can make guitar pedals. Coda Effects Tips Big Muff mods and tweaks. Big Muff mods and tweaks Tips. Noise gate mod. This mod will quieten the Muff while not playing, thus a noise gate.

To do this, add a k trimpot wired as a variable resistor parallel to the k to ground of the second gain stage R The trimpot can be adjusted to taste to get the max noise gate effect. Coupling caps mod. Coupling caps are next to the block of DC also a way to set the frequency response of the unit.

Enlarging these caps give the unit more bass , making em smaller give the unit more treble. Experiment with em. Also the sort of caps can make a difference in noise, feeling and authenticity.

Old Muffs used ceramic coupling caps; using film caps here won't give you the same sound. High roll-off mod. Notice those small ceramic caps on 3 of the transistor stages?

They are used to roll of excessive highs. You can also remove em for a great result. This cap determines the frequency band the unit clips. Enlarging this cap will make it clip more low notes, make it smaller for more high end clipping. The Muff uses four transistors and the type and choice of these transistors will affect the sound greatly.

HappyMod is the best app i have ever used! In addition, the little germanium value is dominated by the much bigger silicon value, because germanium has a different exponential coefficient compared to silicon. If you want to have the typical germanium tone, you have to make sure that the D3 germanium diode is dominating the threshold voltage. If you only want the threshold voltage effect, you need a minimum of two 1N60 diodes in series three is better ; if you want the germanium tone, you''ll need approximately six 1N60 diodes in series to cascade enough diodes to significantly dominate the threshold voltage of the silicon diode.

If you want to be even more flexible, you can also use a 6-way rotary switch to cascade the 1N60 diodes step by step; this way you can blend in the germanium tone from hardly noticeable to full throttle. With this background, you can also experiment with different germanium diodes eg. I hope you enjoyed this one; until next month, God bless and happy soldering. Dirk Wacker has been addicted to all kinds of guitars since the age of 5 and is fascinated by anything that has something to do with old Fender guitars and amps.

He hates short scales and Telecaster neck pickups, but loves twang. In his spare time he plays country, rockabilly, surf and Nashville styles in several bands, works as a studio musician and writes for several guitar mags.

He is also a hardcore DIY guy for guitars, amps and stompboxes and also runs an extensive webpage singlecoil. Sabbadius Tiny-Vibe 69 Review. How to Master Heavy Metal Rhythms.

Task 1. First guess refreshed from theory is that voltage has to increase if the current increases. However, we have to bear in mind, that in this case current flows from anode to cathode. For the opposite, there is no current until breakdown voltage, i.

For better explanation, graph below is provided. Figure 3. Voltage — Current characteristics of semiconductor diode The principal schematic of circuit connection is illustrated below in the Figure 2.

Figure 4. Half wave rectifier circuit diagram Obtained data all tables with measured values, observed graphs and data, calculations : All the tasks were conducted only with germanium diode. As we can see from the table of germanium diode, its voltage and current are related with some function, not proportional.

With the increase of current, the voltage increases and vice versa. For the reverse bias case, there is no current flow. However, there is a theoretical breakdown voltage, approximately volts, after which there is a reverse current flow, usually followed by diode burning Introductory Electronics Tutorial 4 — Diodes.

How does the diode behave as the supply voltage varies? Answer: b in forward biasing the current is very low, until the voltage reaches a characteristic value for the diode, then it increases exponentially. In reverse biasing the current is extremely low, and is difficult to measure. Specifically, channel 1 probe was to measure the voltage across diode and channel 2 was used to test the voltage across the resistor. The principal schematic of circuit connection is illustrated below in the Figure 4.

Oscilloscope connection into circuit Obtained data We achieved the resistance voltage over diode voltage, however forgot to record the camera shot onto phone.

The diode does not let the current flow until breakdown voltage open circuit. After breakdown voltage approximately 0. That means diode is opened and lets the current flow through it. It becomes short circuit constant voltage across it. Specifically, channel 1 probe was to measure the input voltage and channel 2 was used to test the voltage across two series resistors, one of which was variable.

Figure 5. The channel 2 is represented by the blue color, output voltage across series resistors. According to the figure obtained from oscilloscope, we notice that input and output voltages are in phase, however the output voltage has its negative part rectified. This is due to the diode property, which lets current flow only in one direction.
