SIGN UP FOR THE WAITLIST HERE

This will be the fairest for everyone. Joining the waitlist is completely free. You can hang onto and enjoy your unmodded NOTADUMBLE while we catch up on orders, and once turnaround times are much shorter we’ll start letting people off the waitlist in batches (first come first served of course). You’ll receive a notification that you’re off the waitlist and at that time will have the option to purchase the mod. We’ll accept new orders at a pace so that we can keep turnaround times to roughly one week or less. 

Hopefully this is the best of all worlds. You can get your mod as soon as we’re able, but you don’t need to provide your payment/pedal in advance. This will also let us balance mod work with the production and design of our own pedals.

 

About the mod

Our Dumble and Dumbler mod transforms the fantastic JHS NOTADÜMBLË into a fully-capable dual drive pedal. We 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, we add a "FLOW" switch 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.

Watch our video about it here!

"The Dumble and Dumbler Mod really opens up the possibilities of this pedal – the channels still sound amazing on their own, but when you stack them, things really start to take off. ... This particular sets of mods creates basically an entire new pedal, while retaining the sound and legacy of the original." ~ Pedal of the Day

Deluxe (presence knob) variation

JHS ships the NOTADUMBLE 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.

Our Deluxe version of our 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. We find it makes the overdrive channel far more flexible and usable. 

And yes, we have our own supply of "D-style" knobs to match the others!

 

Click here to find the details of the mod for DIYers who want to perform it themselves. However we consider this to be a fairly involved mod of moderate difficulty. We bear absolutely no responsibility for the result of your own DIY activities, and will not be able to help you troubleshoot them. If you are unsure of your ability to mod and want to guarantee success, then let us do it for you! That's the whole point of this!

Include in the box either a printout of your order confirmation page from us, or just write out your name, email address, and order number clearly so we can make sure we know that it's your pedal/kit in the box!

 

More about the NOTADÜMBLË from JHS:

The NOTADÜMBLË is a DIY pedal kit from JHS Pedals that puts a half-million dollars of tone at your feet. With the flip of a slider switch, you can go between two highly sought after sounds that are as magical and rare as it gets. In the Drive setting–slider up–you get the dirty and distorted violin-like sounds you know from guitarists like Santana, Joe Bonamassa, and Eric Johnson. In the Clean position–slider down–you get a powerful preamp buffer pulled directly from John Mayer's rare and never before replicated device. 

Go ahead - save yourself a few hundred thousand dollars and experience the magic for yourself!

Saves time and money
Size: 47pcs, Size: 47pcs
I used this kit to fix a flat tire on one of my lawn tractors from a roofing nail. I used the smallest size (blue vial) and the supplied Phillips screwdriver to screw it in after applying a dab of rubber adhesive. Then I waited about 30 minutes to inflate the tire. The only thing missing from this kit is a set of pliers to pull out any nails or screws, so provide your own if you will be carrying this in your vehicle for roadside use. There are three sizes of screws, and they are steel (I expected that they would be plastic or rubber). The steel will have increased durability. The blue vials contain the smallest screws, the pink contain the medium, and the white contain the largest screws. The screws have some sort of pre-applied rubbery stuff on the threads that I believe helps them stick to the rubber with the supplied rubber adhesive. This kit is easy to use and is a great value for the amount of flat tires you can fix on your own versus the work, time, and money it takes to go to a tire shop. The black look of the screws camouflages the repair, just make sure you screw in the plug far enough into the tire that it won't contact the road or it will eventually wear off the black finish.

Tiny Tire Saver Kit
Size: 47pcs
I really like this 47 piece tire repair kit, it feels solid in my hand and the pieces aren’t flimsy at all. The rubber nails are a good size, not too bulky, and the whole set is lightweight enough to keep in the car without adding clutter. The black color looks clean and professional, and the glue works faster than I expected. For the cost, it feels like a smart buy because you get a lot of pieces and it can handle car, truck, or even motorcycle tires. It gave me peace of mind knowing I can fix a flat quickly on my own.

Convenient repair kit
Size: 21pcs, Size: 21pcs
Great value! It includes different rubber screws, screwdriver, tubes of rubber solution, squeeze tips for the solution, little plastic scrapers to level out and scrape away any excess. Each screw is sealed in a separate little tube container. Everything is in a nice little plastic box making it super convenient! Nice quality and different sizes making it easy to use. Can't speak to durability yet but will update if not as expected.

Finally a kit that actually works
Size: 21pcs, Size: 21pcs
Tried the small nail on a pinhole leak, held pressure for 2 weeks now. The screwdriver feels solid. Comes with 3 glues which is generous.
