Sound of the Week

Plexi Marshall in a Pedal

Mad Professor Loud`n Proud gives you the 1960's Marshall sound in a pedal form. In fact, there is the whole vintage-Marshall signal chain inside the pedal, including the pream and a power amp with phase reverse, push-pull phase and output transformer simulation.

Behaves Like an Amplifier

Thanks to this signal chain the Loud n' Proud doesn't only sound like an amplifier, but it also acts just like one.

The Other Side

The other side of Loud n' Proud is a vintage-style fuzz or boost, which is in front of the amp section. This gives you the classic combinations of fuzz or boost in front of a Marshall amp.
