Vocal-use pedal with XLR - Need some input
« on: January 04, 2019, 11:59:52 AM »
A buddy of mine asked me about making him a distortion pedal for vocal use. He obviously wants XLR in/out (and phantom power if possible, but not required). My knowledge of anything vocal-related is laughably minimal.

If any of you have built a pedal for vocal use, I'd love to  have your input (or give me a link to an existing project). I've done some light reading on balanced vs unbalanced signals, and I have some ideas on how to make it work, but I'd rather hear from direct experience if possible.

I suspect it's going to be a lot cheaper for my buddy to just buy a used Helicon or whatever, but I'm doing the due diligence anyway.

Wouldn't using a FX insert on a mixer with a pedal be the way to go?

Maybe. Can you elaborate?  Do you mean run a guitar pedal in the effects loop of the mixer channel his vocal mic is plugged into?

That’s about the size of it. Otherwise, you’d need a direct box type device, and then suddenly, you’re adding up equipment to carry just for that one effect.

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

if you can find (discontinued) or make one of these. I have one and they are great for many things. It's kind of like a mixer with a send like Alan is saying but much, much more. I heard there is a schematic floating around. I use it to properly use pedals with synths

I built a pedal for a friend based on the $5 preamp that Frederik from parasites studio posted. Can't find it at this moment. The parts cost more than $5 though. The 1na217 in the preamp costs about 5 bucks and the drv123 which converts from unbalanced to balanced also costs about 5 bucks.

Anyway. I took the output from the preamp and sent it to a bluesbreaker. Into send return Jack's. Then into a belton based reverb. After that so many people liked them I've built 5 for other people.

Works really good and is silent. Also added a dry out but most people have wanted one so that the sound guy has no control over their effects. So they just use xlr in and out.

I'll find the link to the vero that he posted but am not at home right now. And add a pic of one of the builds I did.

Edit. Found the vero here. http://guitar-fx-layouts.42897.x6.nabble.com/Microphone-preamp-vero-layout-td5181.html took the send after c4 and return was where that part of c4 was.

Also used a vero layout to do +/- 15v for the preamp/ balanced to unbalanced. And used 2 dpdt relays for the xlr switching on and off.

Looking crappy/diy as i/they like it

I'd go with the pedal in the send/return of the mixer, but otherwise I also have one of these, which is great:

I know its more stuff to carry around, but one of my band mates uses a Cusack Music Pedal Cracker on her pedal board and it's fantastic. Its like a foot controllable effects loop for interfacing pedals with a microphone signal. It does all the impedance matching for you and even has the option to add trails or even have the effect precede you turning it on, plus phantom power. It's super cool. She uses it with delay, reverb and distortion.

Wow, is there a schematic for the pedal cracker? I'd love to try and build it or even just learn some of the concepts it puts into practice
