Fender Champ 600 Master Volume, Gain and (NFB) kit

This kit has all the parts and the instructions to fit a Master Volume control with a Gain and NFB Switch to your Champ 600 (Also suits Gretsch G5222, Fame Tube 5)

The Champ 600 has great blues tone but it doesn't start to give it up until the volume is LOUD.

The Master Volume mod gives you low volume breakup by turning the original volume control into the Gain control that lets you crank up the pre-amp to get an overdrive tone while the new Master Volume controls the signal into the output tube to keep the volume down.
Gain/AA764/5E1 Switch: The Fender Champ 600 has tone stack rather like the AA764 circuit but with fixed values. The Fender Champ 600 Gain/5E1/AA764 kit is extremely simple to install and allows the player to switch between the standard ‘AA764’ circuit and a close match to a ‘5E1’ circuit which gives the amp a different tone and more gain. The two capacitors supplied with the kit improve both the ‘5E1’ and ‘AA764’ tone.
Negative Feedback Switch: The Fender Champ 600 has a Negative Feedback (NFB) circuit that works to eliminate distortion. The NFB mod that lets you choose whether to run the amp with or without negative feedback. Switching out the NFB circuit opens up the amp’s tone and gives it more crunch.

The kit comes with a CD containing the instructions and circuit diagrams as pdf files.
