This section contains general mods for the Fender Champ as well as octal mods for the Valve Junior to turn it into a Fenderized VJr or Mark Huss' Beast! Since the thread index for the Champ is only two pages, current efforts are put into a thread index for VJr's Fenderized Octal mods.

Yup. That's right! We're actually working on the Champ FAQ cuz we do love Fenders too, ya know! Why else would we be spending so much time turning our VJr's into Champs anyway? So if you find any errors, or other threads or mods of interest that you feel were left out and should be posted here, please let us know. Thanks.
