Critic Reviews

Mad Professor Simble Review - Premier Guitar

premierguitar.com

The Mad Professor Simble impresses with its rich, Dumble-flavored tones, especially when paired with smaller amps. Its simple layout and intuitive controls—level, sensitivity, contour, and accent—allow for a range of sounds from clean boost to gritty overdrive. The faux wood grain design is visually appealing, although the brown knobs may be hard to see on a dark stage. While the pedal offers excellent headroom and low noise, the accent control can be noisy at higher settings. At $189, it offers substantial value for those seeking a versatile overdrive pedal.

transparent drive

beautifully transparent and complex overdrive. doesn't do extreme gain settings, but packs quite a punch into a decent clean amp. for massive crunch i tend to run a klon-type overdrive into it to give it a little more oomph.

"I’ve been using a Mad Professor Simble pre-driver pedal when I need to drive the amplifier a little more. I think it’s a brilliant, simple pedal. It’s just got two options—loud and louder—and a footswitch."
