Dumkudo pedal

[sergio]

Hi , Today I tried the Dumkudo pedal, in my opinion nothing special compared to the zen-drive, there are three different modes clipping selectable with a switch.

first position: light green
second position: light blue
third position: red light

Not surprised to hear that. In the end, a pedal is a pedal and will only sound as good as the amp it's played through.

I don't want to hijack your thread, but as I see a picture of the pedal, I see something I have never understood: why would anyone choose to put the power supply connection to the pedal below one of the jacks and not above? I really don't get it.

About 9Vdc supply , I think for the little space!

[ecisthebest]

the DC power jack is there because it fits there. you can't put the in/out jacks with the footswitch in the middle. however, the DC jack fits next to the footswitch in the center.

Personally, I didn't care for the zendrive pedal. That configuration is a bit goofy too! I prefer the stomp switch at the bottom of the pedal, which is possible if you change from Switchcraft to Neutrik phono jacks. The 9V will saddle nicely between the two without causing any issues..

What are the clipping modes? Asym, Sym, and standard tube screamer? It must be a derivative of a tube screamer... Even the zendrive is a TS at heart.

I agree with that philosophy as well. In my homebrew pedals, the power adaptor connects at the "north end" and the jacks are located there so that the wires don't cross. And yes, the footswitch is not in the middle of the pedal, which to me is a asking for trouble as well because you can hit the knobs accidentally.

The pedal got a good review in PG magazine!

I see now there's a switch on the side where you might put the DC adapter outlet. At first I thought maybe it was a zendrive copy, but I'm not sure after listening to it. Perhaps its a continuation of the ZD with switchable alternate clipping options???

I know Robben Ford has ditched his Zendrive in favor of the Dumkudo, so I guess it certainly has something to offer.
I would like to try one, the drawback being the quite high price asked...

I think nowadays most guitarists like to have the in/ out and power jack at the top of the pedal.
It usually allows a better fit on the pedal board.
Although if the next row above the first one is crowded, side jacks can work better.

Can't please everyone.

A lot of boutique pedal guys will give you the choice and of course if you build them yourself, you can put them wherever you want.

When I saw Robben in Portland a few months ago he had his Dumble but he also just had a smattering of pedals on the floor.

I couldn't see exactly what he had but I know from listening he had a volume, way, reverb and possibly a dirt pedal.

Funny thing is, towards the end of the show his amp started making this loud crackling noise, he was kind of distracted by it.
Another TAG member said it was a bad connection on one of his pedals.

This is my latest build

I ordered this enclosure painted and drilled, otherwise I would have put the switch lower on the face.

It's a Burns Buzzaround type fuzz.

It sure is picky about what transistors you use (it has 3 NPN Ge)

There is an Opamp version that uses a TL072 for the gain stages and on the output it uses a single NPN Ge.
Supposed to sound about the same but with more stability.

I have made myself a pedal called Robben Ford Drive, which actually is a Zen clone with diode clipping, must say that I didn't liked it the way it was, I have made some mods (NE5502 instead od TL072 makes nice difference) - changed values of 2 or 3 elements (res/caps), now I like it, but I feel that real amp would do the job better.

[Structo]

Well, you certainly can achieve your dream amp with the information in this forum.
Building a ODS is a big undertaking but one that is well worth it.

[brentm]

@wicker - yeah, Hermida sands his opamp chips... and I haven't tried the NE5502 - I was going back through some notes and I did like the NTE858M. But after a while, swapping opamp chips is worse than rolling tubes... mind plays tricks, etc..

@structo - yeah, that configuration does allow for the highest density of pedals on a board for sure. What Ge transistors did you settle on?

I got a bunch of Tungsram AC176's but most are duds.
