Mad Professor products are superb sounding and built like tanks! I have had the same Delay and Overdrive on my Board for 5 years, I’m a creature of habit, the Royal Blue Overdrive and Deep Blue Delay have made them redundant! Proud to be using the Old School 51, a hugely versatile and dynamic amp and the perfect partner for a pedalboard that helps me perform a legacy of almost 50 years of MAN music!
