Cosmodio Instruments Dumble and Dumbler (JHS NOTADÜMBLË Mod)

The recently released NOTADÜMBLË from JHS Pedals is a DIY Pedal Kit that you can easily put together, and get great Dumble Amp-esque tones out of. It features two channels, but the original design only allowed the user to switch one on at any given time, perhaps short-changing the full potential of this pedal. Well, the fine folks at Cosmodio Instruments have changed all that – come along as we explore their Dumble and Dumbler JHS NOTADÜMBLË Mod…

The Cosmodio Dumble and Dumbler mod transforms the fantastic JHS NOTADÜMBLË into a fully-capable dual drive pedal. They provide a dedicated true-bypass stomp switch for each of its two channels, allowing for easier switching, as well as adding the ability to activate both channels and stack them in series, creating vast possibilities that are not available in the original design. Furthermore, a “FLOW” switch is added to direct signal flow, letting you determine the stacking order — from clean into overdrive, or overdrive into clean.

JHS’s brilliant Dumble-inspired audio circuits themselves are completely intact and unmodified. By activating one channel at a time, you can still achieve 100% of the sounds available from the original design. But by adding the ability to flexibly combine these two circuits you are able to get far more out of them, dramatically opening up new sound sculpting and dynamic performance possibilities.

JHS ships the NOTADÜMBLË with a presence control (for boosting or cutting upper-mid frequencies of the overdrive channel; think of it as a “brightness” control), which is located on the inside of the pedal as a small “trim pot” which can be turned by screwdriver. The Deluxe version of the mod moves this control to a proper potentiometer with a knob located on the faceplate in the position of the stock channel switch. This doesn’t change the sound capabilities of the pedal, but makes it much easier to adjust presence as you would any of the other controls, making the overdrive channel far more flexible and usable.

As you’ll see in our demo below, the Dumble and Dumbler Mod really opens up the possibilities of this pedal – the channel still sound amazing on their own, but when you stack them, things really start to take off. Pedal kits like this, especially sonce they have a relatively low initial cost, are great vehicles for modifications, and this particular sets of mods creates basically an entire new pedal, while retaining the sound and legacy of the original. If you’ve got a JHS NOTADÜMBLË and think these mods are for you, head over to the Cosmodio Instruments website and get on the wait list, this mod has become extremely popular!! Cheers!!
