Introducing the "Cream Pie" !

[Barcode80]

hmm, i think something is wrong with my build. no sound. sound when bypassed so the circuit is the problem. tried tranny both ways. only point i can find in the circuit with no voltage is around the input caps and input resistor. any ideas?

[Gilles C]

After building the Texas Cattle Drive with a CV7112(OC140) with great success, I was just about to build another one on a stripboard to use the other CV7112 I have, but then I noticed the Cream Pie...

Well, it seems it will be my next build after all. It would complement the first one I think. I am just curious to know how different it will be. I just need a bit more guts than the Apollo/Orange Treble Boost variant.

This is a matter of opinion mind you but, I like the Creampie much more myself.
I just thinks it sounds better with my Tele....more "gutsy".

[Gilles C]

You know Mark... I have to think Strat or DeArmond (or even Dobro...) when I build an effect.

But I admit I began to think Tele in my head 

I don't know why, but my wife began to tease me with that  Saying things like "don't you need a Tele to get that sound ?" while listening to some songs... I think she noticed my new interest 

Anyway, even then, I'll have to try it with a Strat for now.

Gilles

[markm]

Sounds like you NEED a Tele there Gilles!! 

[milkwasabadchoice]

Tele's are bad ass! haha! Man Andy, I just ordered three sets of parts so i can build three sparkle boosts for a couple of friends and I. I gotta do a whole new order now to build this thing because of all he hipe! In ya'll's opinion what is the best germ and what is the best place to get it?

Thanks a bunch,

Personal opinion...OC140 / CV7112...its a mullard NPN germ, and they sound and spec out REAL nice....Aron sells them here at the store, IIRC...if for some reason he's out of stock, Steve at small bear has 'em.

I like the NPN because i like having the option of using a regular Boss style power supply. If you just want to use batteries (or a center positive adaptor), AC128's, AC188's, and any of the 2SB's are good. I'd imagine the OC44 / OC76 / etc, etc are great too...it sounds good wih a variety of grems...

You're right about the OC140 / CV7112. I like to use NPNs Germs. And those seem to fit my ear more than the PNPs Germs I tried before.

Finding the right parts for the right circuit is fun...

When both the Cream Pie and the Cattle Drive are boxed, I'll pay a visit to the music store with them, oh just for fun, and to try a Tele with them...
It would be an occasion to get another player's opinion on these build 

These guys sold me my Fender HRD and my Dearmond, so I'm sure they won't mind.

Gilles

[markm]

Actually, you're BOTH right about the OC140 / CV7112, very musical sounding and works real well in the Creampie!
I got mine from Aron!

[Gilles C]

I've got a little problem here. While checking the info that I had about the Cream Pie, I realised that I had a schematic without a revision number and a layout for rev 2. No layout for the no revision schematic, and no schematic for the layout rev2???

What guys do you use?

Gilles

[Barcode80]

well i tried the layout above and have some troubleshooting to do as i have no sound and no voltage coming around the input caps.

[markm]

well i tried the layout above and have some troubleshooting to do as i have no sound and no voltage coming around the input caps.

Which layout are you using?

[Gilles C]

Well I re-read the thread again and found the differences. The different value of the input cap and the change of identification for the parts mixed me up a bit last night. It's better this morning...

Rev 1 has .01uF input cap and a .1uF for 500K tone control.
Rev 2 has a .022uF and no tone control.

It seems that Rev 2 is the standard to build. No need for a tone control.

Barcode80, what voltage do you measure at the tranny, and each side of the input cap?

Gilles

[Barcode80]

i'll check voltages when i get home. but i did build the tone control version. so i will swap it out for the single .022 cap version and see what happens.

[markm]

It seems that Rev 2 is the standard to build. No need for a tone control.

Mine is the no tone control version and it's fine for single coils!
It's warm but not lacking highs.
I have layouts for both versions 1 and 2 in the gallery, I guess the tone control version would be considered 3!
It's just an all around great sounding circuit that's easy to build.
Nice!

[Gilles C]

These are the only 2 schematics of the Cream Pie that I found.

I never saw the schematic of the version 2

And the only stripboard layout on Dragonfly's gallery page is for the version 2

That's why I was asking. So today, I did my own stripboard layout for the Cream Pie version 1, which is the one without the tone control. I also use single coils so it will be perfect.

CREAM PIE V2

Here's my layout for VER3.

[Gilles C]

Thanks Andy!

At first, I was wondering how come I didn't find it... until I saw the creation date

It was originally posted in the gallery and this thread...then i took it down...then i put it up again
