ibanez ts-9 reissue to maxon od-9 true bypass

[czech-one-2]

hi, i've recently modded a couple ts9 reissue pedals with a 3pdt switch using keeleys directions[removing one cap,two jfets,2 resistors a few diodesjumper wire etc]
it really does sound clearer both ''on'' and ''off''.
then i bought a reissue already modded from an ebay seller for cheap $ !
unfortunatly it arrived DOA [cold solder joints?] and the chip wasnt even socketed as advertised. however, i noticed on the true bypass mod he did, all of the right hand board components were removed. alot more than keeleys true bypass mod. the seller is in the process of refunding my money,but he said he copies the maxon od-9  true bypass method.
it seems to me that that is a good thing being that there are far fewer components on the board for your signal to go through. howevr i'm a little skeptical being that the pedal was malfunctioning.
anybody have experience with the ibanez ts-9 to maxon od-9 true bypass mod?
happy holidaze!    bk

oh, this might help, keeleys board vs maxon od-9 board.

About a third of a TS-9 is switching.

[czech-one-2]

yes,that seems to be the case. so why does the keeley mod leave all the components on the board ? are they
dis-abled or is there signal passing through them?

[frankclarke]

There wouldn't be signal going through them, unless he is doing something weird. So it would be OK to leave them there.

[stinkfoot]

Both methods make the signal bypass the switching, so in that regard they are the same. I suppose Keeley leaves the flip-flop circuit in place simply because it is less work than removing it. Also, it could be used to control other functions (a gain boost, for instance). Maxon, on the other hand, builds their OD-9 boards from scratch, so for them it's less work to not populate that part of the board.

thanks you guys.
i knew i could find the answer with your help. thanks for clearing that up for me!
i can see why robert leaves them on,that would probably a thousand man hours a year in his shop!

[czech-one-2]

well, i still have one question.
looking at the maxon board picture, the led wire doesnt go to the zener diod cathode location.
anyone know where the led is connected on the maxon board?
the keeley mod connects it to the zener cathode location.
