Mad Professor Simble Overdrive Mk2: Holy Grail Dumble Tone - gearnews.com

gearnews.com

The Mad Professor Simble Overdrive Mk2 aims to capture the elusive "Holy Grail" Dumble tone with enhanced headroom and clarity. It’s a versatile pedal, accommodating various guitar pickups and functioning well as a clean boost. The interactive controls, particularly the improved Contour and Sensitivity knobs, allow for fine-tuning without overshadowing your amp's character. However, while it delivers dynamic overdrive tones, it doesn’t claim to fully replicate the legendary Dumble sound. With a reasonable price point of €199, it's an appealing option for those chasing transparent tones, but it may not completely satisfy purists seeking an authentic Dumble experience.

“This natural sounding overdrive pedal can work as a clean boost, ‘on the edge’ crunch, or a sweet singing overdrive”: Mad Professor’s refreshed Dumble-inspired overdrive pedal is here | MusicRadar

musicradar.com

Mad Professor's Simble MKII Overdrive pedal brings Dumble-inspired tones to your rig with improved headroom and clarity. With interactive controls for Level, Contour, Attack, and Sensitivity, it offers versatile sound shaping. The pedal shines by enhancing your amp's output rather than overshadowing it, making it a great fit for various guitar types. However, don't expect it to be a Dumble clone; it's more about enhancing your sound than replicating another. At €199, it's a compelling, affordable choice for those seeking to add some 'magic dust' to their tone.
