Guitar amps and/or speakers tend to emphasize extremely high frequencies, the Defizzerator can be used to roll off extreme highs after any pedals or buffers, in the effects loop of an amplifier, or even in a pedal switcher. It can also help an amp sound like it's cranked when using it at 'bedroom' volumes.

The Defizzerator is a simple low-impedance passive EQ with 3 frequencies Fizz 10.6khz, Buzz 4.2khz, and Crackle 2.5khz, are generally higher than a typical Tone or High EQ, so it's useful for really fine tuning the fizz.

THE ZAP CONTROL IS NOT ACTIVE FOR THE FIZZ SETTING, THIS IS NORMAL OPERATION.

The pedal is a low impedance design, so it doesn't add any noise, but of course cables shouldn't be long and wrapped near transformers or power supply lumps to avoid adding any ground loops. This is especially important if using it with an amp, since you shouldn't place it above the power transformer end of the amp (usually near the power switch and line cord).

Since the Defizzerator is passive, you simply patch it in and turn it down.

Also try setting it dramatically and then turn the pedal or amp's tone up more for a different quality high end. Lower settings of the lower frequencies, Buzz and Crackle, might start to reduce the volume some, mostly due to the lack of highs, so you might have to make that up by turning up your pedal or amp's volume a bit - but this is a simple solution that requires no batteries, and you can just keep one in your gig bag to fix any scratchy backline.
