The original 1950s amp designs are FILTHY. Fender had to develop the whole blackface line to try to get loud, clean sounds. A Champ or a Tweed Deluxe cannot hit enough volume to play with other instruments without some distortion. The sound of rock records is often the sound of old 1950s small amps, cranked up. I have a 1950s Supro 5 watt (similar to a Champ) that hardly has a clean sound in it. By the time the volume is at noon, it sounds like what you imagined a wall of Marshalls sounded like when you first saw a picture. Fantastic recording amp. It's that sound, the sound of rock.
