CMATmods Deeelay pedal question.

[Tackline]

Okay so i just started building my very first pedalboard and just purchased a CMATmods deeelay pedal from standard value.

This being the first time that i'm actually playing a analog delay stompbox (Was using multi-efx previously), i'm wondering if its normal for the click of the stomp switch to be amplified into the amp. Meaning to say, when i click on the delay, there's this obscenely loud 'click' echoey sound from the amp.

Is this normal? Or do i have a lemon?

All the other pedals on my board doesn't have this problem.

Here's my set-up:

Guitar --> MXR GT-OD --> Wampler Ecstasy Drive --> Vox Satchurator --> Modtone Aqua Chorus --> CMATmods Deeelay --> Boss RV-5 --> Vox AC4TV


Using the modtone powered pedalboard (not the powerplant)

Any help is appreciated. Don't really want to make a wasted trip down to SV just to find out such a thing is normal.

Thanks all.

It's common among true bypass pedals. Usually this can be cured just by cycling the switch. Just push it on and off till the noise is gone.

 

[justheretolook]

yup its normal, usually the first click will be the loudest and then, no more, but occasionally, it pops. its a normal, but irritating thing.

 

[Tackline]

phew okay. So eventually it will go away? But strange that my ecstasy drive didnt have this problem.

 

[PatheinRaindropMoe]

the popping sound is from the difference in potential/charge build up between "on" state and "off" state for the circuit.

Some effect maker pull in a 1meg resistor as a pull down resistor to between input and ground to the delay circuit.

Anyway, if the popping doesnt cease after repeated on/off, just ask any effect tech to check on it.

A well designed pedal should not have this kinda thing, so its not a common thing btw. The structure of the stompswitch is purely mechanical and should be separated from the audio path. When the popping occurs, it just mean somehow the mechnical switching has cross over to the audio path and amplified.

Hmmm thanks pathein.

Anyways i've been playing around with the pedal for abit and the poppin's still there. I think a charge is built up when the pedal is off and when i turn it on again, 'pop' it goes. So it seems like a cyclical thing? I don't use my delay all the time so when i do need it on, the 'pop' is there due to the build up during pedal inactivity. Tried it numerous times so yeah.

Anyone know who i can go to to get this rectified? Mike from SV doesn't do it i checked.

 

[justheretolook]

hmm yeah better change, i had similar problem with my red repeat delay thats why i changed to a DMM. now my fuzz is doing the same thing, but it is an always on pedal. try guitar connection? cus TY doesnt do it also

Gah and i just bought it on monday...sigh. Someone! Help!! Please!! haha.

I'm not sure how to fix it, but you can use a bypass looper to get around the issue... Leave the pedal always on and use the looper to put it in and out of your signal chain.

 

[PatheinRaindropMoe]

theres a way which might work, without touching the innards of the delay.

Check with tymusic center on true bypass looper, they should be able to customised one for you.

The idea is that with a true bypass looper, you be having the delay in the loop of the looper and permamantly switch one and to bring the delay effect in and out, you will be using the true bypass looper's on/off switch instead. So at anytime, you wont be activating the switch on the actual pedal itself, but through another on/off switch via the looper.

 

[Tackline]

i'm hoping to spend as little money as possible cuz all my recent pedal acquisition has me kinda dry heh. how much are said loopers anyway?

 

[PatheinRaindropMoe]

Check with tymusic center for quote.

if money is an issue, take the time to save up first or google for true bypass looper info online. Its one of the most common and easiest pedal to diy as it doesnt involved much things other then mechanical switches/ phonejacks and led.

 

[Tackline]

alright then thanks man appreciate the input.

I found this bit of info about the popping noise here: http://www.singlecoil.com/tb-strip/tbstrip.html

Must I use a pulldown-resistor to avoid popping noises when engaging a true-bypass loop ?

Read what Andi Allan has to say: "I'm starting to feel a little doubtful about how much this can help. It works for TBing a pedal by modding it, but may not have such an influence when you're building a bypass strip. The idea is that it prevents a DC offset that could be caused by old or bad decoupling capacitors in the pedal in the loop. It only really works well, though, if you do it physically close to those decoupling caps. I basically do it if and only if I have popping problems, in which case I put a 1M resistor across the sleeve and tip of the return jack. I wouldn't go below 1M". My 2 cents ... on a stompbox you can use a pulldown-resistor to avoid popping noises by simply solder the resistor across the sleeve and tip of the input jack. The value is not very important and everything from 1M to 4.7M will work fine. I use 1M and I can´t hear any influence on the tone.

For loopers, parts-wise they are dirt cheap, since it's just 4 jacks a switch and some wires, no electronics at all. You can check TYMC. Don't go for branded ones that cost as much as actual effects pedals.

edit: aiyo beaten to it by pathein again

 

[Tackline]

Hmmm...the resistor soldering solution seems to be more cost effective than a looper? Plus i don't have to waste pedalboard space. The question is, who knows how to do it? Haha. Anyone know of anybody on this forum who is well versed with stuff like this and can actually do it?

 

[PatheinRaindropMoe]

it will only be cost effective if you are doing it yourself.

For effect tech guys, you will have to pay for their man hour charge. The cost of the component is prolly negligible, in this case of a resistor.

 

[Tackline]

But even if paying for the labour shouldn't exceed 70 bucks i guess? Cuz that the price i was quoted by tymc for a single looper. Ah well, will probably bring the pedal down to GC on sat to see if they can add the resister. Or are there any other shops that for sure does this sorta thing?

 

[Tackline]

Okay i kinda solved my poppin' problem without spending any money so i thought i'd just share.

Basically i read somewhere online that if you use a buffered pedal before the 'problem' pedal, there's a chance that the poppin will go away. Not too sure of the technical reasons, but yeah, i tried it, rearranged my pedals with the cmatmods now in between my dd-3 and rv-5 and viola! no more poppin.
