Emma ReezaFRATzitz
Just when you thought you had seen the strangest name for a stompbox, EMMA offers up the Reezafratzitz! Like its unconventional handle, the RF-1 is a unique type of OD/Distortion unit that stands out in an extremely crowded playing field. The RF-1 offers incredibly rich, full-bodied crunch that is so close to tube-amp overdrive that you'd be hard pressed to choose which was which.
The secret to the RF-1's amazing tone lies in its Bias control. This knob allows the user to morph between Class B and Class A biasing, altering the harmonic structure of the signal and providing a much wider variety of tonal options than your standard distortion. In Class B mode, the RF-1 exhibits a thick, chunky grind similar to a Marshall or Fender amp. Class A mode provides sweet, singing saturation worthy of the finest Vox AC30. Additional controls for Level, Gain, and a Hi Boost/Hi Cut Tone circuit allow the user to fine tune the RF-1 to taste.
This is what I could find.
Yep, I know that one (haven't heard one though). It's made in Denmark (like me) and is supposed to sound real good.
They also make an envelope filter- the DiscomBOBulator- which is supposed to be nice as well.
Could be fun to see a schem of the Reeza-whatsits...

yeah...I think the same...but it's covered under epoxy!
The Emma pedals are fairly recent releases, catering to a fairly small market so far. It is only fair to keep information about them protected so that however many people that enterprise is attempting to provide a living wage for can continue to do so. If the need for a schem is to repair or mod an existing one, then simply contact the manufacturer. If the end point of this is to take the circuit and push it into the public domain, that's another thing again.
So, the question is "Need or want"?

I need it for modding one! I had Reeza and really liked it but it's not so good in mix...kinda scooped and doesn't cut so well. So I need scheme to do it.
Then I think the best thing to do is tell the Emma people EXACTLY what you want it to do differently, and they can probably tell you "lift this resistor here" or "make that cap larger in value", or whatever. They may even be able to provide you information that avoids future problems with the pedal.
One of the things one always has to remember is that every pedal-maker has a vested interest in having their pedals perform well when an owner trots it out in public. Everytime you use it in front of someone else that can be good advertising, or bad advertising. They want more of one than the other.
The other reason to contact them directly is that if the pedal sounds much better on its own than when combined in a mix, that is something they should hear and know about for purposes of product improvement.

OK, have sent...will see ...
Good, fingers crossed, and hope this works out for you. Here's hoping they know how to run a business.
If you find a way to contact Emma, let me know. I have a DisCumbobulator that I'd like some info on. They certainly don't have high profile.

Here are the guts of the ReezaFRATzitz:

As you can see, a half of the PCB has been soaked in plastic to prevent reverse engineering.
Wow.....
Cool shots. Stupid RE protection
I'm still waiting for reply from EMMA...
I've received reply! Actually I expected that answer.
"Glad to hear you like our pedal. As you said, the Reezafratzitz is sealed
in a large block of epoxy so there is no real way to modify it. What amp are
you using? is it possible to turn up the midrange or presence on your amp?
This would help a lot as it's usually the midrange that will give you this"
in your face" sound. What settings do you use on the pedal? There are some
modifications that can be done before the pedal is sealed but this would
involve making a new pedal for you. Please get back to me.
Kind regards,
Tim Campbell
EMMA Electronic"
Well, that was a courteous, prompt, and professional as I would have expected. Good on Tim! :icon_smile: Of course the problem is the big black monolith which precludes you doing anything. :icon_sad: The companion problem is that whatever amp-setting changes might make the pedal sound better to your ears may be unacceptable for a bypassed tone - dumb to have to change amps to make a pedal sound better.
One last-ditch effort might be to take a picture of the copper side, crop/reduce it to the smallest reasonable filesize, and send THAT with a request to identify any possible points where you could add a parallel component or cut a trace to attain the desired tone.
Just be sure to heap on praise for the pedal in the note. Boutique builders are like your grandma: show 'em that you liked what was on your plate and they'll be happy to give you second helpings.
We're down...but we're not out yet.
if you really want to modify it, you'd better figure out how to eat through that stuff. :)
i wonder what they use... i was recommended to plywood-glue. apparently it's just about invincible
this is a cool company, they do nice work. i don't think a scemmo is to be found. it you find one,........... i'll from a dirrent source.

ps: not to be negative but to be REAL,....................peace bro. :icon_cool:
So, guys, what do you think is it possible to remove all that plastic from PCB?

Oh yeah, a chisel tip on your soldering iron will do the trick nicely.
Though, if you don't want to destroy all the components, best to use heat, a dental pick, and lots and lots of elbow grease!
I just have received e-mail from Emma...kinda negative answer about modding...
I'll have to discuss with my partner about if we will do these mods for
you. This is not something we normally do. If you need more gain I'm afraid
that you'll have use another pedal along with the Reezafratzitz or hotter,
more midrangey pickups or amp.

Troublemaker!
There IS a schem of this pedal out there. It is on another DIY forum that (iirc) is not allowed to be linked to for whatever reason.

Insert this into the partial link above. gro.sexobpmotseerf (it's backwards here)
No big news here. It's basically yet another Craig Anderton Tube Sound Fuzz, according to the reports...
<yawn>
Kind of puts a different spin on that "sealed in epoxy" circuit board, methinks. I guess this just never gets old...

The ReezaFRATzitz is a very high gain pedal and sounds nothing like the TSF.
Looks like it could be slightly based?
It's modded, of course.
Still throws the gooping in a different light than intended.
Gooping is intended to make you think "this is so speshul it must be kept secret" when in fact many times what it really means is "you've seen this one before, so we must wrap it in an aura of mystery to ensure there's interest in it".
I don't really care either way. T'ain't no big deal to me. I'm not in now nor will ever be in the market for boutique distortion pedals. I'm just telling it like it is.
gooping cracks me up... designing/building pedals isn't the hard thing. It's the selling of them that is hard. It takes ALOT of hard work to continuously sell enough pedals to make a living at it, but alot of guys can sit down and whip up a pretty kick ass overdrive in a matter of minutes.
I'm get a kick out of the people who epoxy crap just so no one will find out its a fuzz face, tubescreamer, or rat clone!
:icon_mrgreen:
I tend to agree with you. At least from my perspective as an engineer. Designing is relaxing and fun. Building is a little more hassle but still fun. Selling is something else. I've never really got up the chutzpah to deal with it. It seems too much like work. Hell, I start nodding off just trying to come up with a big parts order list. I've got a day job. It's fun and I'm happy with my income. What do I need a night job for? (I don't even order parts at my job- I design and build stuff... I'm one spoiled S.O.B...) Building the same dirt box 500 times seems like too much of a grind. But sometimes I think it would be fun to throw a couple "originals" up on Ebay just to see what happens. Just gotta get through that parts list first...
Robert Kiyosaki (I think - rich dad, poor dad author) once said something like "there's a whole world of difference between being the author of a best *written* book and the best *selling* book...

To the Original Poster,
Instead of hacking up a pedal and killing it's resale value/warranty, you can definitely do something outside the pedal to better suit your needs. I noticed you probably wouldn't want to change your amp settings in order to get a sound out of the pedal that's more suitable for your specific needs. What if you made a true-bypass loop and hardwired a booster at the input or output of the pedal? This way you can get the desired extra gain or mids/presence. It would be a simple fix, which would eliminate the need for taking the pedal apart, "de-gooping," tracing the circuit, then trying to figure out how to mod the pedal.
