The Carvin Valvemaster is an all-tube guitar amplifier from the late 1980s to early 1990s representing Carvin's entry into the premium tube amplifier market alongside its solid-state lineup. It features a clean channel and a higher-gain lead channel, both voiced through EL34 power tubes for a slightly British character uncommon in Carvin's American lineup. The Valvemaster is one of the more tonally interesting Carvin designs.
