All About Germanium Transistors

"Learn why germanium transistors are vital elements of vintage fuzz, distortion, and boost pedals."

"If you're looking for classic fuzz tone, nine fuzz freaks out of ten will tell you it has got to be germanium. Not only is the germanium transistor viewed as the warm, furry beating heart of myriad ’60s fuzzboxes and booster pedals, it’s also considered a must-have ingredient in countless high-end recreations of these aural delights. It’s important in many modified and original designs, too. But what is a germanium transistor, and is it absolutely essential to viable fuzz tone?


Germanium is a semi-metallic element that was used to make transistors, diodes, and other components that were widely used in consumer electronics until more consistent and more reliable silicon components became available in the late 1960s. As far as solid-state circuitry goes, they are the “old technology,” and have developed a reputation for a decidedly vintage mojo that remains in vogue today. These are the transistors that help classic vintage pedals such as the Maestro Fuzz-Tone, Dallas-Arbiter Fuzz Face, and Colorsound Tone Bender do their thing, while also providing the far-from-linear drive tones in the legendary Dallas Rangemaster, Vox, and Hornby-Skewes Treble Boosters.


Although different makes of germanium transistors often had different characteristics, the more desirable types are considered to yield a sound that is warm, rich, and extremely dynamic. They can also range from crispy, bright and jagged to muffled, smooth and dark, or anywhere in between—factors that are also dependent on the circuits in which they are used. In the more popular pedals, they are universally considered to be extremely tactile, yielding a great playing feel."

My National Panasonic RF-5000 has 20 high quality germanium transistors.

I am glad it arrived in good restored condition.

I would be afraid of having them swapped out if I sent it somewhere for repair.

This actually happened with an old Sony reel to reel I sent to a shop.

1. Hey, your buddies in cali decided that your HAM radios and efforts were useless and needless.

The only thing I can tell them is that you can't run both ends of a cell phone conversation with a battery backup or generator, but you can with HAM radios.

We can only hope that it is their children at risk when they need that kind of help.

5. From the American Radio Relay League...



"ARRL officials who have also looked into the situation agree that it’s been blown out of proportion by parties with their own agendas.

“The State of California has not made any determination we can find ‘that Ham Radio no longer a benefit,’” Pacific Division Director Jim Tiemstra, K6JAT, is quoted on the Sacramento Valley Section website. “What happened is that CAL FIRE has transferred responsibility for its communications sites to its property management department. That department has the task of evaluating each site, its condition, use, and tenants. If a repeater not known to be associated with the emergency management function of a local jurisdiction is found in a CAL FIRE vault, the default action is to move it out or subject it to commercial rental rates.”

“Our contact in the California Office of Emergency Services suggests that, if any affected repeater is in any way involved with local emergency or government support activity, they should ask that agency to engage with CAL FIRE concerning the repeater. If the agency makes the case, there is a good chance that the repeater will be unaffected,” Tiemstra added.

ARRL Southwestern Division Director Dick Norton, N6AA, has been responding to inquiries with the same message."

2. Remember the 'Talk Box'?

Peter Frampton used one.
