More often than not the person doing the layout uses the pinout of the substitutes they have at hand, yet still lists the original part.


Thanks Seiche - I appreciate you taking the time to reply and I'll be especially careful of that in future :)

Hello people.

This is my first post in this great forum, which I always read.

I just wanted to upload a PCB I made for Formula 5.
BOM, PCB and Layour on *.rar file.

PCB is verified, put it together with a COT50 from La Revolution Deux.

Catalinbread - Formula 5f6

Postby mganzer » 14 Nov 2013, 15:56

Hi Guys; Anyone put the hands in one of that? someone knows what changes from formula n5?(aside from the obvious tone stack changes)?

If anything, fed with humbuckers this pedal has too much gain. Any suggestions for reducing the gain?


Hello, schematic painters and signal tracers,

first, i wanna thank you for your good work. I built the Formula five last night and it worked immediatly. However, i wondered, why it clips a little bit hard with gain all down, when played hard. Especially with humbuckers, as you may have expierienced. With LTspice, i simulated it and changed the 62k input resistor to higher values, and changed it on my Formula 5 to 1000k. I've seen on the pictures on the first page of this thread, that it should be 620k instead of 62k, because the rings are blue red orange instead of blue red red. Could someone please verify this??

These days i will try to match the transistors. For that purpose, are there some recommended values, or is it ok as long as the transistors are in a similar region??

Greetings
Thomas

It's pretty obvious that it`s blue-red-orange, but that means "62k". 620k would be blue-red-yellow...
Does it sound better/closer to the original pedal with the 620k?

In another version of my vero layout I noted "C1 is 470pF, not 47pF" - but I don't remember, where that came from. Was it mentioned in the thread before?

You are right. It is orange, but for some reason i had another factor in mind. so it is 62k.

I can't say that it is closer to the original. But for me, it works better because now i control the clipping only with the gain knob, not with my guitar volume knob anymore. I simply didn't like it, when the first clipping stage came to clip. Of course, the overall gain is lower with this modification. I don't know whether i will keep the mod or not, i will test it for a while.

So it seems there was a Mark II catalinbread formula no5 with (reportedly) some differences in circuit/components (and then a Mark iii, which was just a paint job supposedly) - does anyone have any idea about the differences?
(I'm not talking about the newer 5f6 by the way)

Yeah roseblood the correct value is 470p It was my pedal originally and I made the mistake labelling it 47p, but that error was cleared up and the correct value was definitely 470p
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

I have an original Formula 5, I'm curious what's different here. - Is it just the tone stack?
- Sounds nice.

I built this pedal with an extra footswitch for the 2M resistor (thanks IVIark!), but the box I have is drilled for four pots instead of three so I'm wondering what I can put in that fourth spot.

So far I'm thinking a voltage starve or a bass cut. What do you guys think would be more useful? Alternatively I could make that last pot into a boost pedal (sho or rangemaster), but I really like the built in boost effect of switching out the 2M.

Catalinbread 5F6 formula 55

Postby Nocentelli » 04 Feb 2017, 16:36

Anybody seen gutshots or (shock horror) own one? I'm tempted to buy one with a view to tracing and I'm interested in finding out if they are SMD

Would really like to see the Formula 55 traced...

There is Formula №5

Presence control will look something like this
Although in an ideal it would be to see the scheme

I built that years ago...

I'm making a Dirty little secret to practice until someone publish the schematic of this one.
I hope it will be soon, as I don't have one I can't help too much.

In most european countries it's possible to buy a pedal online and then to send it back without any cost. Off course, that's not a nice way...
