- All vintage USA Big Muffs have source-date codes stamped on the underside of the potentiometer cans, or “pots”.

I've read about lots of people changing out the cap values on their tone pots for different pickups, with lower values allowing more treble into the signal.Germanium and silicon have several different characteristics that might draw you to one instead of the other.Germanium fuzz will act a lot like a dirty tube amp, and even clean up when you roll back your guitar’s volume, in most cases. Germanium also tends to be more mellow, rounded, and overall, more responsive.Would removing them entirely do something similar, or would it only affect how the tone pots darken the sound of the instrument? This set up provides a good lead guitar sound but I don't know how these mods sound with germanium diodes.great pedal, quite simple but sounds perfect.The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits).

When dating an instrument by the ‘pot code,’ keep two things in mind: The potentiometers must be original to the piece (new solder, or a date code that is off by ten or more years is a good giveaway to spot replacement pots); and the pot code only indicates when the potentiometer was manufactured!

The codes were created by the Electronic Industries Association (EIA) in 1920s to identify the product source and date of manufacture.

The first string of numbers is usually the part number, or sometimes the pot value.

In the simplest terms possible, fuzz is simply what your guitar signal sounds like as it is being literally destroyed.

It found its way as a very useful semiconductor material by the late 1940’s and helped in moving a lot of electronics away from the use of vacuum tubes, ushering in the beginning of the solid state era.

It wasn’t until the 1970’s that silicon was introduced as a type of transistor material.
