I wasn't sure which forum to post to since this isn't a "Build your own", so I apologize if I'm in the wrong place.  Please point me to the correct forum, move my post, etc.

I've been searching around trying to find mods to convert some of my Boss pedals to true bypass.  I found a post for the conversion of my DS-1 and finished it yesterday and I'm quite pleased.  So now I'm trying to find mods for some of my other Bosses.  I found the following marked up schematic for the MT-2 that this guy used to make a clone:



It appears to me that if I:

1.  Pull Q009 (in the red box in the upper left) and jumper across S & D (the outside pads) as shown with the blue markup
2.  Pull Q002 (in the red box in the lower right) and jumper across S & D (the outside pads) as shown with the blue markup
3.  Pull Q009 (in the red box in the upper right)

That should hot wire it "always on" and I can then wire up my 3pdt on the inputs. outputs, and LED.

Does this seem right to those who know more about this stuff than me?

I realized I typo-ed item 3.  It should read:

3.  Pull Q003 (in the red box in the upper right)

What about q004??? Should I pull on too???? and make a bridg between base and emitter?¿?¿?¿ Or what?
