Introducing the Mad Professor Loud 'n Proud, a compact pedal that encapsulates the essence of a vintage 4-input Marshall amplifier. This pedal faithfully replicates the complete amp signal path, including the preamp, phase inverter, push-pull stage, and output transformer simulation, delivering authentic Marshall tones in a pedalboard-friendly format.
Authentic Marshall Tones: Emulates the classic sound and behaviour of a vintage 4-input Marshall amp, capturing the essence of iconic rock tones.
Dual Boost/Fuzz Options: Features a pre-boost capable of adding up to 13dB, enhancing midrange presence, and a vintage germanium fuzz for a range of tones from clean to thick, warm fuzz.
Character Switch: Offers two voicings—tight bass with slight compression on the left and looser bass with maximum dynamics on the right—to suit various playing styles.
Comprehensive Controls: Includes Bass, Middle, Treble, Gain, Volume, Presence, Fuzz Volume, and Boost/Fuzz knobs for precise tonal shaping.
True Bypass: Ensures signal integrity when the pedal is not engaged.
Designed for guitarists seeking the classic Marshall sound without the need for a full amplifier, the Loud 'n Proud offers versatility and authenticity in a single pedal.

"The whole experience felt completely different from any guitar store I've been to. It felt like a private gallery."
"I traded in two guitars towards a PRS Private Stock and the whole process was handled perfectly. Fast, fair, and totally transparent."
"Bought my first boutique guitar through The Vibrato Bar. The attention to detail from the setup, the packaging and the follow-up was all exceptional."
