Apparently it's Jfet based and a really cheap pcb. Somebody repaired one over at the other forum.

I'm willing to bet it's a Jfet emulation of whatever amp he is famous for using.

traced the pics from paul marossy's website. http://www.diyguitarist.com/phpbb/viewtopic.php?t=864&sid=37971546b4d6a27248d5a03d718b418f. i think that the last fet has the opposite pinout of j201.
this is the only schem that i saw which has the drain grounded and the source connected to V+ via a resistor.

thanks for the trace! you should be able to view the original pics by right clicking and hitting view picture. but really, the best way to go about it is to attach the files. this also reduces the amount of possible broken links we might have at the forum. thanks!

I am NOT impressed with the build quality of this thing.

Assembled by monkeys if you ask me.

I hope it sounds better than it looks.

Fck. That's serious DIY crapwork.

Is this pedal traced already? In that case the schem can help to determine where traces go to where it's not clear dus to using flashlight while takking the photo's.

Then,
Rework the photo to a black and white layout. Make a board. Determine the values of the resistors, electrolit, pots and trimmers and start soldering.

in essence,
These photo's contain too little information for a clone.
Sorry. Plain out of planes.

That are pictures of orginal device... so it works, i don't have it at home, i have just find some photos of the board, and i think about clone of that device...

Who is the manufacture of this pedal, just so I know and can avoid buying anything from them in the future. Real poor build quality.
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 ?

Well they figured out how to do graphics anyway , Hope Becker is getting something out of this [ if anything ,
depending on the sales maybe they're letting him down ! ]

I will attempt a tracing, it is good enough to probably trace 90% of it since the structure (cascaded jfet) is straightforward

Just so I know: what makes all of you say the construction is SO bad???
Crooked pots: that could also be from the guy who removed 'em to take the pic no?
Wires not super-neat: while I agree they could look better, that (to me) doesn't mean they're not soldered solidly or too long or something else that could be negative on the overall function of the pedal...

What am I missing that makes you guys state it's that bad? Educate me folks!

Quality of the solder joints is always a prime factor
crooked pots look done in order to solder directly to other components , not a bad idea
unless you have to take it apart , For any pedal , you'd expect it to get thrown around a little as you gig
and you don't want it to fail on a gig because it wasn't made well enough to last .

Bare tinned copper links on the switches could easily be bent inwards, causing shorts. These links could have been made straight, and sleeved, which would have looked more professional.

The unit looks to have been assembled in a hurry, and as cheaply as possible. It doesn't inspire confidence, and it doesn't make me want to invest any of my hard-earned cash in any of their (Protone) products.

Thanks for the information and pointers guys! It'll help me make mine better (I only build for myself but still).

Having just seen the Blackeye Effects Buffer thread, the Becker pedal looks like Rolls-Royce in comparison. :twisted:
