Dunphy Imports | | Expect To Pay: $350

Of all the guitar amps in history, one goes down as the most elusive of them all. Lauded across the world for its rarity and exclusivity, an original Dumble amp will set you back tens of thousands of dollars. But if you’re playing the same gigs I am, chances are you don’t have that kind of coin to drop on a car — let alone an amp. Luckily for us working musicians, you don’t need to aim that high. Mad Professor’s Twimble — a smart pedal that combines two ODs in one — calls to mind this exact tone.

Some of the world’s most respected players have used Dumble amplifiers, ranging from Robin Ford to Santana. It’s a tone that can be described as rich, thick and bolstered by a distinctively throaty mid-range hump. For the most part, these amps are cherished for their natural sustain that blooms forth. For the most part, the Twimble will get you in that territory — as well as offering some very useful tweak-ability along the way.


Using the level control, you’ll be able to use this pedal to control the drive of your amp. Moreover, it’s useful to think of the controls of this pedal in the same way you would your amp — allowing the colouration of the Twimble to accentuate your base tone with something distinct.


The Twimble combines two of Mad Professor’s most successful effects; that being the imple overdrive and the Simble pre-drive. Combined into one pedal, you’re offered the ability to choose either or both. Used on its own, the overdrive function is throaty and rich — think of that classic Dumble tone we discussed earlier — with room to fine tune your frequency with the contour control to taste. Sensitivity determines the amount of gain on tap, while contour works in tandem to effect the pedal’s output. When set correctly, you’ve got enough room here to nail out a distinctive growl that’ll work well for a plethora of genres and playing styles.


With the pre-drive engaged alongside the overdrive, things really start to heat up. The pair work together incredibly well — boosting your guitar’s signal into a killer lead tone that sings. Capping it off, a handy hot and cool control allows you to either reign the effect in or pull it back in depending on how much distortion you’d like to flirt with.


A very responsive pedal, it works particularly well for dynamic players as well as responding nicely to your guitar’s volume. Roll the volume knob back a couple notches and it’ll clean up, with room to move back into those singing leads when you’re ready by rolling your guitar’s volume knob back up. It makes for an organic playing experience, that’ll have you sorted for multiple scenarios.
