Rebote 2.5 Delay echo guitar effect Demo, I built it

[monkeyxx]

incredible...thank you

[wnorcott]

@monkeyxx Thanks Brother, glad ya like it! Thanks for listening.

built this pedal and for some reason i can't get it to work. If i turn the repeats all the way up it oscillates with the delay knob [so the big IC is working], but it just seems like the signal isn't making it all the way through. I've tested every solder point and the connected ones. Double checked all resistors and caps. Voltage regular is function properly. part 2 coming

[Walls1441]

@Walls1441

I don't have an oscilloscope but as far as i can tell the opamp is working (the first stage definitely works but trying to test the second one overpowers my multimeter's shitty AC function. I've tried like 3 different TL072s so i doubt all of them have an absurdly out of range SNR. No leads are touching, i really can't figure this out. True bypass works just fine. no led or anything

[100roberthenry]

whats the longest delay time on this?......

[wnorcott]

It can get about a half-second of delay or a bit more.

Bill

[MrBatch73]

At 1:14 I went to another time and era, amazing sound. Well Met Sir!

[BlisteredBones]

heyy this pedal sounds really awesome even better than a boss or mxr. great work, love the infinite delay it's real clean an sharp

[wnorcott]

Thanks, glad ya like it.

Bill

[BlisteredBones]

no problem, u have any plans on selling ur pedals

[wnorcott]

Yes check out my link in the more info section I actually have a company that sells pedals that I designed. Check out my channel page wnorcott too.

Bill

[mendebil]

@BlisteredBones don't you have to replace a resistor to get infinite delay?

[Walls1441]

@mendebil you can connect two wires to a dpdt switch then on one side place the 10k (for infinite) and 15k on the other (regular version) then stomp on the switch to change between. Or you could connect one lead of the 10k resistor and connect the other lead to a 5k pot and have a similar effect.

[rginnett]

Reminds me of the fx from the 70's Star Trek episodes! I'm inspired by your work.

[educamargo17]

Hi, wnorcott. On tonepad's original schematics there's a level control, but in your there's a blend control. How did you mod this control? Just doing the mods that you said before?

Sorry if I wrong the english!

[wnorcott]

Hi, yes, my Blend control does the same thing. I just did the mods I said before. Thanks for listening

[lalomania1]

hey wouldnt a 5 buck adapter cause hum? i've heard they are not correctly filtered. thanks man, i already submited this comment 3 times but it doesnt seem to get posted

[lalomania1]

Do you know what is the current draw on this pedal? Could i power it with 5volts? Thanks!

[wnorcott]

Thanks for listening!  I have not measured the current draw and I do not want to the power jack apart to do so but I bet it is less than 50mA.

It is designed for 9V and cannot power it on 5V. There is an internal 5V regulator because the PT2399 itself runs on 5V regulated. I have run it on 12V but it sounds distorted.

[lalomania1]

Hey thanks for the quick reply. I just got the crazy idea of running it using a USB cable as a power source. I would convert the usb out from 5v - 500mA to 9v - 270mA. Do you think it could work? Also, how long could i espect a 9v battery to last using the PT2399? Thanks a lot, yours has to be the best sounding version of this pedal!

[wnorcott]

I just posted another Rebote 2.5 demo about 5 minutes ago.

I bet you would get about 10 hours out of a 9V battery.

If it were me I would buy a 9v adapter they are pretty cheap like 5 bucks.

Bill

[pliniorock15]

well, could you tell me.. where you put the 5v regulator?

There's some mod. in it to get endless repeats?

By the way.. this delay is VERY MUCH NICE!

congratulations!

:)

[wnorcott]

The 5v regulator is put between the +9V rail and the ground rail. The +5v out powers the PT2399 echo chip.

Soory it took 1 month to answer I was not paying attention.

Bill

[probablyjoel]

I tried building this pedal and for some reason it just doesn't work at all... its Driving me nuts! No sound, nothing. grrr...

[XF3DeX]

sorry if you ve answer to this question.

how much $ for building

[drunkgorilla]

i got the yamaha aw1600, and it really is a great recording tool. great riffs

[sittingboo]

Congratulations. You built the awesomest echo pedal ever.

I bet "Astronomy Domine" would sound godly on that thing.

[yuriharrison]

Thanks, Your delay is amazing.

;)

[yuriharrison]

Please can you tell me the IC that you used in this pedal?, you made it with the informations from tonepad right?

Thanks.

[wnorcott]

It is a PT2399. Yes the original design is by Francisco Pena at Tonepad (and I credit him in the video). However I modified the hell out of mine so it is now quite a bit different from Francisco's design.

Bill

[theblacknight88]

it really is cleaner and brighter,you did a very good job!

[wnorcott]

Thanks. I have been informed I have the cleanest sounding Rebote on the planet haha.

[FabioBlood]

Hi! can I ask you what type of capacitor use you for this pedal?

[wnorcott]

I used metalized polyester capacitors

[alecjahn]

Also, I'm just using the standard IC2. The place I originally ordered parts from didn't have either alternative, so I stuck with that one. Surely it wouldn't be THAT horrible.

[wnorcott]

Well Tonepad will not tell you to use metal film resistors but if you want low noise effects that is what you need to use just the same. You can also change the op amp pretty easily. You did use IC sockets, right? If so you can slip in a different op amp that sounds cleaner than the TL072. You will find that getting a clean sound is all in the details.

[wnorcott]

Sorry I deleted your other comment by accident the Reply button is right next to Remove. Anyway at this point you can resolder the connections and switch out the op amp if you like but definitely use shielded cable on the input because that makes quite a difference

[wnorcott]

Actually I take it back, I looked at the circuit board again and I used carbon resistors on the Rebote. I used metal film on some of my other pedals like the Phase 45 and the Tonebender.

[alecjahn]

I built one of these a few weeks ago, and have a problem. The repeats are very dirty and just downright crappy. Definintely not as clear and clean as yours are, but definitely not even close to an 'unmodded' build should be. Any hints?

[wnorcott]

An echo pedal has to be very clean in the original signal because the feedback on the echo increases the noise.

Here are some questions. Did you use shielded cable on the input? Very important to do this. Did you use 1% metal film resistors? Carbon are noisy. Did you use metal film capactitors except for the ones marked as pF values? Are there any loose connections or cold solder joints. Try reflowing the solder. What are you using for the op amp IC?

Bill

[killitb]

Using your mods, I got my rebote sounding sooooooo smooth.

MANY THANKS TO THIS MAN RIGHT HERE

[hyppie89]

Awesome!!!!!!!!!!!!!!

[magnusFTW]

Awesome!

[oneinchmen]

Cool job, wnorcott!

Unfortunately, I can't seem to find your list of modifications in the comments... Do they get erased over time???

If you'd be so kind to repost them or even add them to the description on the right?

Thanx!

Harold.

[wnorcott]

Resistors: 15K -> 6K8 24K -> 22K 240K -> 220K 510K -> 470K Capacitors: 0.082µF caps -> measured 0.09 uF 0.027µF -> 0.033 uF 51pF -> 47pF 5pF -> 4.7 pF I also changed IC2 from the TL072 to the LM2904 which only uses 1/6 as much power and lends a much brighter and crisper sound Bill

[bravelittlebeemer]

Holy crap, I'd pay good money for one of these. Very nice build!

[wnorcott]

Thank you my friend, I appreciate the kind words.

[killitb]

Amazing pedal, I really really like that mod.

Unfortunately I have not been very successful at finding many reverb pedal schematics, only one digital reverb on tonepad.

Have you ever tried making a reverb pedal? Im trying to make one for my friend.

Thanks

[wnorcott]

4.7 pF capacitor is a standard part it should not be hard to find. Capacitors that small are marked in pF not some small number uF. When concerted to uF it would be 0.0000047uF but they are not marked like that they are marked 4.7 pF Look at my series how to make your own pedals part III

If you build a lot of pedals get an assortment. Check out eBay seller sureelectronics he sells a 1,000 piece assortment of ceramic capacitors for $17.999 USD including free shipping.

[killitb]

Oh ok I see, thanks.

I am buying all my parts from Smallbearelectronics and effectsconnection and neither of them have capacitors that small.

But I read in one of your other posts that 3PDT are too expensive, but effectsconnection has 3PDT footswitches for $3.75.

But I also see how they are not really nessecary for you.

Thanks for all the help. Now that I have gathered all the parts and info I should be making pedals in a few days. yay.

[irxthewrld]

nice sound give me lessons plzzz! the machine is hot give me his number watch my vids echo is coooooool!!!!!!!!!!!!!!

[EVSIOR]

Amazing. Do you think possible add some outputs for 2 expression pedals that let me control the feedback and delay time???

[wnorcott]

I have never done this but suppose you could in theory, if you were to replace the 2 potentiometers with stereo jacks and plug in 2 expression pedals. But the resistance values of the pedals would need to match the potentiometers on the effect. I leave this as an exercise to the reader.

[adrianvdb]

drug effect pedal lol :P

[TeddieFish]

AMAZING SOUND! Better than the Ibanez DE7!

What mods did you do?

Amazing sound...

[wnorcott]

Thanks. It really does sound nice if I say so myself haha. I use this in a lot of my recordings too. I have changed quite a lot of components to make it work my way, if you read all the comments in one of them I show all the parts I had to change to mutate it. I changed the integrated circuit also for a cleaner sound than original.

A lot of it is worksmanship, I work really carefully and use shielded cable on the input

[TeddieFish]

Shielded cable on the input side.. Why didnt i think of that?

The only problem with this effect is the PT2399. Its hard to find.

[3amsleep]

hi, i liked your mod a lot!.

im planning on bilding one my self, so i was wondering if you could lend me your mod specifications, or mayber a little schematic ^^ please.

[wnorcott]

Read all the comments please -- in on of the comments I do list all the mods I made to it. Glad you like it, thanks.

[3amsleep]

yeah i already read it, but im hoping for a explanation on how to mod the circuit so it sounds "clearer".

i supose you changed some caps and resitors, but if you can tell me wich ones you changed, and wich value you used i´d be very thankfull.

[3amsleep]

ooo sorry i just realized i didnt read all the comments XDDDD.

thxx

[xxcorexx]

i've noticed some noise during pauses, i think it also adds noise when cascaded with any dirt pedal?

[wnorcott]

The noise in a few spots when I pause is not from the Rebote 2.5 echo. I have a AMZ Compressor hooked up after the echo. When you pause there is no sound going into the compressor so it keeps trying to turn up the volume and that brings up the hum that is how compressors work . I was sitting too close to the PC and the pickups get hum from the PC. Recommend playing into the echo first, then hook up distortion boxes after the Rebote 2.5

[rock4nick92]

hey man great work... fantastic sound for a small pedal

[wnorcott]

Thanks!

[kamilkubik]

Wow! Awesome :) You made bypass of DPDT switch?

[wnorcott]

Thanks for the comment. Yes, my Rebote 2.5 is wired for true bypass by using a DPDT toggle switch instead of a foot switch. You don't really need an expensive foot switch for effects pedals you can also wire up a DPDT toggle switch. They are a lot cheaper than a foot switch too, it only costs about $2 for the toggle switch. Make sure you use shielded instrument cable on the input and the output jacks, it keeps out the noise and hum.

[wnorcott]

I just posted a new demo of the MXR Phase 45 phase shifter clone that I built that one is also worth checking out. If you click on the first Video Response above it takes you to my new demo of the Phase 45.

[505371]

Hi!  I loved the high and midrange mod. It really sounds clear. What parts did you changed to perform that mod??

[wnorcott]

Thanks! Here are the altered components in my mod: Resistors: 15K -> 6K8 24K -> 22K 240K -> 220K 510K -> 470K Capacitors: 0.082µF caps -> measured 0.09 uF 0.027µF -> 0.033 uF 51pF -> 47pF 5pF -> 4.7 pF I also changed IC2 from the TL072 to the LM2904 which only uses 1/6 as much power and lends a much brighter and crisper sound

[505371]

Man you are my hero... soon you'd be able to check my new rebote delay at 3w. clacpedales . blogspot . com

Thank you very much!!

[wnorcott]

If you like the Rebote then subscribe to my videos. I am uploading my latest pedal the Ampeg Scrambler which is the strangest sounding effects pedal ever heard.

[505371]

hahaha, what a coincidence! i'm doing that pedal too!

I'll be looking forward to hear your creation (sorry for my english. i'm from chile)

[wnorcott]

I posted 2 video responses which are demos of my Ampeg Scrambler. The two demos sound very different from each other. One is crazy and the other sounds almost normal

[PLUMBdogg]

great demo, i've been thinking about building a delay myself but i'm trying to save up some money for a new amp. a delay can really do alot of different things when tweaked right.

[neiloler]

Way cool Bill, a lovely build. I love the knobs too, those are awesome!

[wnorcott]

Thanks for the kind words Neil, I appreciate it. If you want to get some of those same brushed aluminum knobs they are available at the Electronic Goldmine their part number is G16542

My other videos use some of my other effects I have built.

[wnorcott]

By the way friends this is one effect you really want to run on AC power, not batteries. I built mine so it can use an internal 9V battery or else you can plug in a 9V adapter. This effects pedal eats 9 volt batteries -- they only last about 2 hours -- so it is better, and the sound is more stable, using the adapter instead of batteries. The demo was made using the 9V adapter.
