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:

STE 245

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!

Beautiful!
Size: 8, Color: Haze Blue, Size: 8, Color: Haze Blue
My daughter got engaged in these shoes and walked all around Paris in them the day of. In all of her engagement photos the first thing everyone notices is her shoes! They are a beautiful powder blue and matched her dress perfectly. She reports they are comfortable and fit true to size. She even purchased another dress when we returned to match them just so she’d have more opportunities to wear them. I can’t imagine anyone would be disappointed in these.

SIZE UP IF YOU ARE A HALF SIZE!
Size: 8, Color: Black
If you are a half size DEFINITELY size up! I am a 7-7.5, but in heels I’m usually a 7.5. I ordered an 8 and it fits perfectly!! They are super super cute but surprisingly not as comfortable as I thought considering it’s a pretty small heel. It’s not unbearable but I would keep that in mind if you’re planning to wear them standing for a long period of time. I didn’t see many reviews about people with half sizes except one and I listened to that one review and I’m very thankful I did. So PLEASE size up half a size.
