LET'S MOD: Behringer VD400 Vintage Delay - longer delay mod

[@lundsweden]

The pedal is analog BBD, but yes I like the extra grime and artifacts on the longer setting. Everything is so clean these days and lacking character, so this is really welcome!

[@johnt.campbell316]

Holy frigging crap, dude. This is awesome. It's neat they put those internal knobs in there. I'm definitely doing this. Thank's for the information.

[@TimWhittSound]

No worries. How'd you go with the mod? Find a sweet spot that you like?

[@johnt.campbell316]

Yeah... I prefer a quite _faster_ delay, so I went with clock-wise to get it faster, but with the main knob I can still get some slower delays... Plenty for what I need. I did't turn it *all* the way down, maybe about a 1/4 turn on the knob. Once again though, dude... *Great* information.

DIFFICULTY GETTING THE LITTLE SCREWS BACK IN: 10/10 But a great little mod this... thanks for the vid!

[@baguette273]

My experience is - I did the same - the repeat rate knob isn't that sensitive after this. I mean the rate is fairly the same in the lower 50% after that it quickly changes. And the rate went down marginally. But it does work.

[@daniblve4695]

Gosh I’m about to buy one of these 😌 Thanks for your video

[@sweatycrabthailand4262]

wow, thanks my delay pedal is now useful, and such a great easy fix!

[@zAvAvAz]

Great built in tweakability for easy modding without soldering!

[@xdanielpk4161]

Thanks! Got me that dotted 8th that I wanted.

[@miss.wright3035]

Change the pots with 1K ones and you'll get some really wacky space echo effect

[@jat5am]

pots of the regular 3 knobs? have a vid with the results?

[@jacobsamano9761]

Thank you this is awesome information 😊

[@lefterisden2389]

freaking cool man, what helluva mod!

[@Vitotesta]

WoW! It works GREAT! THANKS!

[@Lespaul13100]

Hi, I removed the screws( top and bottom) and the top still won't come off. Is there a way to remove it without breaking it? Thanks.

[@xdanielpk4161]

Lespaul13100 what I did is remove the knobs first then took it off because the knobs where causing it to not take the top off

[@Lespaul13100]

Daniel Santiago Thanks!

[@RippSnortin]

Good mod thanks. You could actually unfolded that internal pot and add one the you can control from outside with case closed. Also, carefull with those conductive screwdrivers around the chips. You might let the smoke out.

[@infectionsman]

Haha Fantastic! I was expecting to have to do some tedious resistor/pot change or even change the clock rate of a chip!

[@ctrlaltdelete1159]

Wow just bought it today. On it's way.

[@TimWhittSound]

They're surprisingly good for the money. Behringer does have some pretty under rated gear. How are you finding it?

[@lostlanaya8927]

fabulous man! thanks

[@bigstick5278]

You have the case open you mess with two of the inner pots but just say "I don't know what this one does" and don't even try messing with it?

[@miguelmoreno2355]

Does It works with a Bass? 😅

[@iplayloud2]

This is a Boss DM-2 copy correct? So are these the analog delays that did compromise tone quality for longer delay times ?

[@StonefieldMusic]

What can be done if I wanted to make it really long, like 600 or 800 ms? Is there a component that can be replaced?

[@1redgate8]

Doing this will get it to 600ms

[@ivo51505150]

Hi, I have a Behringer DD400 and I noticed that it changes the tone of the guitar when I turn on the pedal. I would like to do a MOD for true bypass. You know how to do? Thank you!

[@semajsemajsemaj99]

Same , plus , it's like the delay is the same everywhere. You loose high end after the adjust

Wow men thanks!

[@Kestrel-zc1du]

thanks!

[@nelsoncolereis4058]

I just adjusted the trimpots inside. Now the delay time is longer. But at long settings there is a high pitched noise. Maybe clocknoise? How do I get rid of that?

[@1redgate8]

Just did the same...I turned the middle trim pot only a couple of degrees clockwise, it it appears to have disappeared. It is certainly not notable anymore to my ears.

[@destroso]

@@1redgate8 the one above echo or intensity?

[@JoeyLevenson]

Doesn’t every analog delay have that. It’s a trimpot, not a mod.

[@filterdrive]

Great stuff, but if it's a true analog delay I don't understand how there could be digital artifacts. If it employs some kind of noise-reduction technology, which is digital, it may struggle to reduce noise over the extended delay - maybe this produces the artifacts? Anywhichway, great stuff, really appreciate the mod info!

[@S1NKONE]

BBD chips are neither digital nor analog because are time discrete. They sample continuous analog values but they do this at certain time intervals. This causes sampling artifacts. This is my understanding of it please correct me if I'm wrong. EDIT: The artifacts are filtered with a simple low pass filter.

[@javiceres]

@@S1NKONEYou are right my friend.

[@chanbara8683]

Im tim im kyle. ..whitt..we related my dude? Jk

[@denisshannon3626]

Nothing long about those delays, should go up to a second

[@rockpapercloud9930]

Dont try guys this method its nearly destroy my vd400 it took me hours to adjust back to its normal state

[@gypsysteve3576]

Destroyed in what way ...like nearly broke it? Overload to electricals? Or destroyed as in; tone change?

[@elti-buron1462]

@@gypsysteve3576 well the circuit is updated, I ended up breaking it entirely, stopped working. wasted 31 dollars, my suggestion is just be very careful because its super sensitive, once adjusted to your liking try not to repeat the process too often or it'll come off like it did in my case, sad because i bought it for this purpose only, probably just gonna spend 100 bucks on the jhs delay.

[@OttosTheName]

@@elti-buron1462 These trip-pots aren't meant to tweak a lot like 'proper' pots. The name also kind of implies it, you set it and you let them be. Unlike normal pots they are often rated for 1k turns, but it's quite possible they put in some pretty cheap trimpots because the user isn't supposed to touch them (often). Or maybe they aren't put on very solid.
