Here's a demo of the Amptweaker DeFizzerator, into a Kustom Defender 15H with Peavey Classic 112E cab, and later into a 64 Princeton. The DeFizzerator is a simple low-impedance passive EQ that can be put in the loops of Amptweaker pedals, in the loop of an amplifier, or used with a switcher system like the RJM Mastermind PBC, to roll off sizzly highs. It has 3 switch settings for frequency, labelled Fizz, Buzz, and Crackle. For more info go to amptweaker.com.
The amps were recorded with a Peavey Vandenberg guitar and using an m-Audio Microtek with its built in mic, and an iPhone for the video and voice-overs.
