The vintage 4-input Marshall, just has that classic and rebellious rock tone we have all grown to love. It helped to define the classic hard rock tones of band and artists including AC/DC, Cream, Jimi Hendrix, Led Zeppelin, Free, Yngwie Malmsteen, and many more.
Mad Professor Loud´n Proud is a vintage 4-input Marshall in a box. It’s a compact pedal with a complete amp signal path replicated inside. Not only the preamp but also the power amp containing phase inverter, push-pull stage, and output transformer simulation. This internal structure makes the pedal not only sound but also behave like a real amp.
