"A box later" Dumble

[rccolgan]

Thank you for taking the time to review! I appreciate the honest feedback

The guy in NC who Played Dr Billy's Dumble used a Box-alator, sounded of course AB INCREDIBLE Videos may stil be up..Steel Bender Dumble

Somebody needs to buy the new JHS NOTADUMBLE and trace the "A box later" side of the circuit. Apparently JHS traced Mayer's original unit

i just ordered one myself actually

[award70]

Me too! It comes with goop to put over the circuit.

I'm gonna use it to hold the caps to the board in my 124 build lmao (if it's suitable)

Heh. I saw the JHS video this morning and ordered one.

That's the plan here

It's kinda funny, if you watch the video (https://youtu.be/n9wNpgWJhYo?si=8whdWRmtI36zh45J&t=210), a few things stand out to me.

• The original Dumble unit is not a JFET boost based on our gut shots (Thanks, Gil!) Perhaps he means a JFET input Op Amp? Or did he actually just take a FET boost and put it in the pedal

• The JHS is only 9v input. From what I've seen from videos putting it together, I didn't recall seeing a boost so it's the bi polar supply like the original

• I noticed when I built my circuit, the "return" knob would thin out the tone quote a bit. It wasn't until this video that verified that I'm not crazy and/or my educated guess was not wrong with the circuit

• I wouldn't put it past Mayer to request that it's not exactly the same circuit. Too many examples of being thrown off the trail to truth with his gear

• Josh said the original Dumble labeling is Input & Output but it's actually Gain & Recovery on the exact unit he screen shots before

Uploading my latest schematic. I did a few extras to keep the pedal quiet, lots of headroom, and tweakable.
I did a big blog post too https://www.thetonegeek.com/single-post ... or-fx-loop

Any plans to reissue the PCB/kit sale? I could do with one

Yup! I have been very slow proving out the v2 design (too slow, I guess!) and it works better than I thought! I'm trying to wait until the tariffs cool off before ordering v2 boards from JLCPCB but grabbing onto this momentum might make the investment worth while...

I thought tarifs will affect things over $800 only? Its hell of a PCB sets for over $800

An idea i humbly offer up: when you get your hands on the JHS you can figure out how to convert it into a proper 4 jack box a later and sell mods perhaps? IDK but If I had known yours was in V2 development I wouldn't have bought the JHS. If you can find a way to do it without ordering more PCB's that would be a way to ride the momentum!

De Minimus is the $800 threshold and that is gone now as of May 2nd. That's why Temu and the like are raising prices if shipped directly from China.

In a way, I'm hoping the Chinese can just clone my pedals so I can focus on something else haha

This is a good idea. Once I get mine in I'll see if there is room to do such a mod. There is a lot of folks asking for a foot switchable option between clean and dirty channel too.

Darn...

Either way, good luck mate. Im still down for one. Most likely two, as my friend is building a Dumble, too
