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! 

 

Where do I send my pedal/kit?

If you are shipping us your pedal to mod, or sending us a kit directly from JHS, address it to our workshop:

Cosmodio Instruments
200 Great Rd
STE 245
Bedford, MA 01730

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!

Price and quality are excellent
I appreciate the price and amount I get, I included one of this toys in each of the puppies bags for when they go home with their new family. They are strong, feel and looks of good quality. I can't speak for their durability, my puppies are Yorkie and in the majority of the cases this toy is bigger than our puppies. They arrive fast and they are better than we expected.

Perfect Stuffed Animal
Bought these as a gift for our dog and he absolutely loves them! We haven’t even given him all of them yet because they’ve held up so well. Normally he destroys stuffed toys almost immediately, but these are surprisingly durable and have lasted much longer than expected. The only thing he seems determined to chew off are the ears — apparently he has something against stuffed animal ears 😂 Luckily my fiancé just cuts them off before giving the toys to him and they’ve been great after that!

Bad squeakers
These toys are so cute, but they come vacuum sealed, so all the squeakers were out of air and broken. These are unusable.

No working squeakers
These toys are very durable but the squeakers do not squeak. They were sealed in an air tight plastic bag which permanently collapsed the squeakers.
