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!

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!

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds. I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges. Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

Good Quality Bag
Even though I'm a self-declared "coffee snob", I roast coffee primarily as a discipline of returning to some of life's basics (I also make homemade pasta, bake my own sourdough bread, and have an herb garden that's to die for.) Word of my hobby is quickly spreading, though, and more and more friends are offering to pay me for a batch of fresh-roasted coffee. Enter the need for these bags, which (so far) appear very well made and easy to use. It does take a bit of practice learning how to get them fully sealed and protected for transit. That written, I did not lose a single bag to the learning process. It CAN be a bit of a challenge fitting all the roasted beans into the bag, but sufficient tapping of the bag on the counter eventually causes the beans to settle and fill in all the little gaps.

(Mostly) Well Constructed and Seals Tightly
This is my first experience with ready-to-fill sealable coffee bags. I normally buy coffee in resealable bags (12oz seems to be a standard size) and while convenient, they tend to be more expensive than buying coffee in cans. With these bags, I am now able to buy a large canister of coffee, empty it into the Maestri House bags, seal them up and enjoy the convenience of a resealable package at a more affordable price point. The bags are sturdy and thick and feature a "freshness" valve that allows you to squeeze excess air out without ambient air getting in. After filling the bag with fresh coffee, I sealed the top with my existing vacuum sealer (the kind used to preserve meat, etc. for freezing) and it worked great. The only issue I encountered, on the first bag I filled, was that the little tab that you hold in order to remove the thin foil strip that initially covers the resealable zipper tore off as soon as I started to remove it. It was a bit difficult to grab the remainder of that strip in order to remove it. That did not happen on the other 3 bags I've since used, so don't know if that's a common issue or not. Besides coffee, you could store a variety of items in these bags. We're thinking of filling them with candy (e.g. gummy bears), sealing them up, then giving them away as favors at upcoming graduation events. The included self-stick labels will allow us to personalize each bag.
