Hi! I was wondering,

Is there a layout for this one or is it one of those "protected" ones???


  sorry for asking if it is!

foxx tone machine

it's the same circuit??? the SAME??

[jonathan perez]

give or take a couple tweaks and turns

there's a layout + pcb here on Stuart Castledine's site----- http://homepage.ntlworld.com/s.castledine/greenfuz/experience.html

it's the same circuit??? the SAME??

The first two stages are and exact copy. The "swell" function is an exact copy of Anthony Leo's entire distortion pedal from a Popular Electronics project of 1968.

Do a search on "experience pedal" and you should find my earlier explanations of this.

I read somewhere that the swell schem was incorrect; also, is it worth using as a separate unit? or even doable?

thanks

I read somewhere that transistors are really made of cheese inside - germanium is Stilton, high gain silicon is Limberger. 

I'm sure that at least one schematic for this is incorrect, somewhere. But which one, and how? 

They left the output capacitor off the A.Leo fuzz to let it change DC bias as signal is applied. This forces a tube amp input to be off-biased until a signal forces it back on. The "swell" effect is caused by the output of that fuzz manipulating the input of a tube amp.

It's a garden-variety silicon transistor fuzz from the late 60's. Some people will like it, some won't. It's entirely doable, as there is a buildit article for making them. I think the poptronics article has been scanned and is on the net somewhere, but it's been years and I'd have to go dig through search engines to find it.

thats funny I like cheese humor

Thank you very much everyone!!

thanks for the explanation R.G.; I am an inexperienced forum member to be sure, but had no idea I warranted cheese... :]

No wonder so many of my builds stink!

Sorry if I sounded snotty. I just have this knee-jerk reaction to what even smells slightly of FUD - Fear, Uncertainty, and Doubt. Members of the Computer Industry That Was used FUD to keep customers from buying competitors stuff until they could get a new version in that they could sell, and hearing somewhere unspecified that something might be incorrect was a good technique for doing that. You walked right into that with a vague attribution.

It was no doubt well-intended to mean "Check your schematic source to see if it's correct", which is perfectly accurate to say, and which does not set off my FUD-o-meter.

I have a copy of the original article somewhere in the archives. I even saw the original article, as I was a subscriber at the time it came out.

No need to apologize; I agree with you and am of the firm belief that there are plenty of companies who still use that same kind of tactic - it seems to be a pretty standard negative marketing tool.

But I would not presume to question you or many others on this forum. What I was after, and this is the precise reason for my logging on to this forum nearly every day, was accurate info. Since discovering this site and a host of others, I have been downloading and doing my best to learn about this whole DIY thing. I have discovered in my quest for knowledge that there is a great deal of heresay, old info, and rumour, and there is a multitude of reasons for that. I was hoping, simply, for verification or at least a good clue (cause I am the beginners beginner) and this is the best place for it.

Sorry for going so off topic... 

thanks

Components on the left side of the PC board, starting at the green wire coming from the middle lug of the volume pot, are the swell circuit. Everything to the right is like the fOXX tone machine.


I just got a used Dano French Toast pedal, & it is reportedly the same as the fOXX. Sure sounds like it to me, & the price was $17, shipping included. I plan on re-housing it in a better enclosure & converting it to true bypass. I may also try adding in a separate board with the swell circuit in there.

what exactly does the swell sound like?

thanks

thanks for the link! it sounds pretty good; it'd be cool to switch in/out the swell.

oh jeez, it does, doesn't it? oops - type too fast for brain...
