Thanks to its excellent tone and versatility, it is a great amplifier for practice and studio use, and it can even be used for playing in clubs.<\/p>\n<p>Our Big Master Champ is built using the same techniques and materials used in the 1950s in order to achieve the most authentic tone. It incorporates an additional *Master Control* that allows you to push the great tone of this circuit even further.
