That's what I'm talking about... true bypass without hacking up the box!
Made me a little board for it:
I wrote an article about it in my blog.

Very cool stuff Soulsonic!
I would add some more pictures of the component side of the board.
It would also be interesting to see the millennium bypass and switch connections in a generic edited Boss schematics. I think it would help a lot in the understanding of how you implemented the idea.
Thanks for sharing.

Thanks guys!
For the LED switching, I used the "Millenium 1" with a JFET because it has the least number of components. I used a J201 and it works great - though in the original article R.G. said the JFET Millenium does this slight fade-in thing on the LED, but with the two that I've done so far, the LED comes on instantly without any noticeable fade-in. Maybe it has something to do with using a higher-current LED?
I will see about drawing up something to illustrate how these kind of bypasses are done... but it's fairly straightforward and simple. I removed the two transistors for the flip-flop to disable it, and I replaced the switching FET with a jumper. Then, it was just a matter of hooking up the I/O wires to the bypass switch in the usual way.

Soulsonic making history!!
an elegant solution... of course (I prefer non drilled boss with no true bypass).
Is a great Boss pedal Update!!!
PCB?? or stripboard?? Thw whole world needs it!

I put together a schematic that shows the Soulsonic’s True Bypass implemented starting from a Boss DS-2.
I hope you will find it interesting.

You must replace the stock switch with a miniature DPDT. That's what the small board is used for - it holds the switch and the JFET circuit for the LED switching. I did the first one on plain perfboard; it's very simple. The only trick is getting the height of the switch adjusted so that it will actuate correctly with the foot treadle.cpm wrote:thats nice if the switch is dpdt
other pedals i've seen use an spdt so it not so easy

thanks for the information, i wanted to mod an old american metal pedal

have anyone the schematic corrected? i think that the old attachement is not the soulsonic one.
thanks a lot for share

Hi!
There is a quick way to defeat the flip-flop circuit used in BOSS effects by simply pulling one resistor.
The circuit and defeat is detailed here, Page 3:

Omit Click-Less™ True-Bypass installation and substitute your switch of choice!
