Detail 01
Modified volume circuit
Breaks up more gradually for more precise gain adjustment and aims for tighter bass with improved overdriven definition.

Independent shopping perspective
Pro Junior IV keeps the control layout direct: Volume and Tone drive a 15-watt tube 1x10 combo with a Jensen P10R speaker. Its modified volume circuit is designed to break up more gradually, giving you more precise gain adjustment across clean and overdriven settings. When pushed, that circuit also targets tighter bass and clearer definition. Lacquered tweed covering, ’50s-style grille cloth, a chrome control panel and leather handle give the amp its vintage-styled presentation.
