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!

Love this sink organizer
This fits really well alongside our sink. Keeps the soap containers off the counter so the water drains off and keeps things much neater. When the tray is full, simply pour the water out, rinse, and put back.

Missing Dividers
Color: Black, Size: 9.4*4.1*5IN
Disappointed it was missing the adjustable dividers. Not great to hold dishwashing brushes. They slip right threw the side.

Sturdy. Built to last. It solves all the problems my old organizer had. Very satisfied.
Review for ARTLEO Kitchen Sink Caddy with Super Water Absorbent Diatomite Stone Sink Tray, Fast Drying Sink Organizer with High Dish Brush Holder Sponge Holder for Kitchen Sink, Stainless Steel This appears to be a sturdy organizer of stainless steel painted with a good amount of black protective paint. I ordered it to replace an inferior organizer of the same material (made by a different company altogether). This one solves the problems I had with my previous organizer which had begun to rust and break apart after six months of use. The narrow steel bars on the bottom shelf of this new organizer are supported by wider steel flats in the frame that will prevent them from breaking off the frame. (My old organizer bars broke because they were barely welded onto the frame and the repeated "pushing down" of my soap pump-bottle eventually broke them apart from the frame). The pads that prevent it from sliding across my counter in big waves (we live and travel on a boat) are secured around the steel legs as opposed to just being glued onto the bottom (like the pads of my previous organizer were, which fell off). There is no metal hanging over onto the sink edge to cause rust (like the metal that had caused rust with my old organizer.) The dish-brush holder can fit on the inside of the frame or it can hang on the outside of the organizer, which is nice because it makes more room if you have many tools that you like to use at the sink. And it can be compact if you don't. Be cautious not to remove the hanging part (dish-brush holder) too often because repeated wear can cause the paint to rub off and it could begin to rust. The "Water Absorbent Diatomite Stone" is new to me but it seems to be working just fine. I assume I will have to clean out the ridges of it as gunk forms there, but that would be the case with any sink organizer tray. I am very satisfied with this organizer, it is robust and it solves all the problems I had with my previous one. The price is on the higher side of similar organizers, currently priced at $23.99. All the best, Mrs. dr

Great design for a kitchen sink organizer -- will not tip or accumulate water
We've had an Oxo kitchen sink organizer for years, and it's been fine, except 1) tall brushes (for example, Oxo brushes) make it tippy, stray elbows or imperfect placement of the brush would knock it into the sink and 2) it built up a soapy sludge in the bottom that that had to be drained and wiped down constantly. This item solves both issues perfectly. Likes: Size - I think it's about 5 inches deep, which is just right to fit the strip of countertop that runs behind the sink, up against the backsplash Weight - The drying stone in the bottom gives the baskets some real heft, so there is no tipping it over by bumping a brush handle -- it really stays put Drying stone -- The diatomaceous drying stone that slides into the bottom of the main basket is a great idea. These are porous stones that will absorb water and then allow it to evaporate fairly quickly. So far, it seems to be doing its job well. I'm sure the stone will need a wipe down now and then to stay clean, but no puddles of sludgy soapy water in the bottom is a big plus Overall Design/Build quality -- The unit seems solid. It's a simple design, but there are no sharp edges or unfinished bits. Once in place it doesn't wobble a bit. I wasn't sure about the black powder-coated finish, but installed it looks clean and it's unobtrusive. I appreciate that the smaller basket for tall brushes sits on hooks and can be hung inside or outside the main basket. Ours sits inside, but there's plenty of room left over for sponges . And there's still room to stand up a bottle of liquid detergent or counter-top spray. NOT SO LIKES Nothing so far. I notice a lot of this style of sink organizer on Amazon, so presumably they're selling well. It's a great improvement over the older kinds. Five big, clean, well-organized stars. Highly recommended.
