I just bought a Fender Champ 100 as an upgrade from my practice amp. Is there a decent site out there that shows how ALL the effects and controls work? I pick up bits and pieces as I go along for now. For example in channel 1 I have volume treble bass and FX level, but I dont know where to set the FX select for a clean sound when playing country. I currently just have it OFF. Any help is appreciated. Thanks
