CE1 Ensemble crunch by - schematic

[Amitay3333]

Doe's anyone know what is the correct ce 1 ensemble crunch schematic by Triungulo Lab? I want to build that pedal in order to get john frusciante tone and maybe I will  combine this pedal with CE2 + vibrato mod= new 9v boss ce1 but I'm not shure how its gonna work... I have couple of pics that show the inside of that pedal from Triungulo Lab facebook page i dont know why he use 2 op amp although the ce1 schem show 1 op amp amd he use much more capacitors... I will be very greatful for any help!😊☺

So I take it this is just a CE-1 'Preamp'? In that case I'd bet that extra chip is a charge pump for a split rail supply.

yes you need to have +/- 13v  if you want to stay true to original

I think if the ce1 ensmable crunch is good i will stick to the 9v

[Amitay3333]

Great thnx but still i need to do it with 9v

[Amitay3333]

someone know if it will work, to do the exact original preamp schematic( with same components values....) with a 9v power supply or that I need to match the components to the 9v? and if so please someone help me build a schematic+ spleat rail supply ...☺ by the way what r those two diodes in the pedal i dont think they related to the spleat rail supply...

Excuse the crappy cut and paste job but this will probably work if you want a 9 volt version. I might give it a try if I get time.

Thanks!!😄😃 but still the ce1 ensmable crunch have two op amps and two diodes and the level pontentiometer need to be 500ak sisnce its mod of the ce1 boss chorus... I want it to sound the same as the ce1 ensmable crunch plus lu didnt change mutch the schematic is that mean that i can low the voltage of the boss ce1 and get it work?

Do you know for sure that both 8pin chips are op-amps?
One of them could be a negative voltage converter so it can run from + and - 9v dual supply from a standard 9v pedal power.

Lol I mean to say two IC dont know what tipes... and yes I just need it to be exacly like the ce1 ensmable crunch and the only thing i know about this pedal is that its work with 500k potentiometer and the rest that i know is from the pic😀

[Amitay3333]

Pls Can anyone build me the ce1 ensemble crunch schematic with two ic and the two diodes and 500k pontentiometer Im so desperate 😆😆

Frusciante's "tone" is also:

his guitar, the strings, the pick, his fingers, the amp, the microphone on the recording, the signal processing on the recording, the console, the plug-ins, the mastering, the radio's board or your stereo's amp, etc.

if you're so desperate to make this pedal thinking it will make your guitar sound the same as his, unless you do all of the above, don't bother with exact

😂😂😂 what? do u think  I'm a begginer? i know batter then u about john fruscinate tone I'm trying to do this pedal because I can... and it will help me to have batter tone. And I need beter commpressing signel and buffer for my rig. i'm not a freak of tones it just will be batter with that pedal.

Welllll, this attitude isn't going to get you very far. If you can do it, then do it.

If you aren't going to provide more information about this pedal then people here are going to make certain informed assumptions about what is going on with the pedal. They aren't going to do all of your research for you.

Others have already mentioned that the original unit runs at +/- 13 Volts. There are two ICs in the pedal that you are trying to emulate, but the original CE-1 Preamp section only has one IC in the preamp. You've also mentioned that the "Crunch Box" runs on 9V. This all makes it fairly safe to assume the first IC in the Crunch Box is something comparable to the original CE-1 Preamp, and the second IC is a MAX1044 or ICL7660, or something similar, that is taking your 9V DC that you plug into the pedal and turning it into something closer to +/- 13V. This arrangement is typically called a "Charge Pump" circuit.

Either way... if you come into this forum ready to learn and asking questions then people will be very helpful and friendly. But if you are just going to demand that others help you, while ignoring any information that has been provided (everything I summarized was already written in this thread by other users), then you aren't going to be successful. Just my 2 cents.

relax tough guy, you're going to have to grow a little thicker skin if you're gonna keep using this internet thing.

did you get my point? maybe i was rude, i apologize. try building it, prototype or breadboard or whatever. A/B it with the recording and tweak *by ear*. You will never in a million years get the same tone if you only replicate his gear, the recording process is 50% of "his" tone. Even if all the engineer did is throw a 414 in front of the cab it's still colored and definitely altered in the mastering process. You can compensate for that by starting with something that is basically the same but don't get bogged down in component specifics because you will only waste your time and money. Tweak by ear until it sounds the way you want, this is the only way. And show some respect to the forum, I don't necessarily deserve it, but there are a lot of very knowledgeable, experienced, much nicer people here that do.

There's not enough information in those photos to tell you how to build a copy, you're going to have to do what Garcho suggested and experiment a bit to get what you want.
Here's another crappy schematic showing how to add a charge pump to get +-9 volts. This is probably pretty close to the pedal.
If you want a 500k pot swap the 50k in the schematic for one, don't know why it would have 500k though. The diodes could be in the feedback loop of the opamp, like a tube screamer but that would be a pretty big change compared to the original circuit and almost makes it pointless using a charge pump.

Thnx!😃 sorry for asking but its my last questions. .. I saw two diodes in the end of the original ce1 and next to theme its said peak level maybe its mean something?... and now I realized that I need to get the pedal from 9v to 13v and -13v(to split the voltage) how can I do this? with witch IC?and how can it be done with only 1 IC? thanks u very match  for the support😊

[tonight, we ride]

can u explaned to me pls how it can be possible to still have the same components but with 9v and still get same sound?

My last post in the thread addresses this. You plug in 9V, the charge pump turns it into the +/- 13V the components use.

Oh okk thnxxx💓 can u show me only last ones how can i done it pics of the IC maybe? Thank u very mtch!!😊😊

[Amitay3333]

And if someone knows why next to the diodes said peak level and maybe what they r doing in the ce1 ensemble crunch that would be great!! Thnks for everybody that help😍😍😍 u r great guys!! sorry if I hurt somebody 😊
