Title: boss sd-1 bleed is annoying the hell out of me...
Post by: John Egerton on February 02, 2006, 07:15:45 PM
hey guys...

i've read the reports on here and i have tried switching the 2 FETs with J201's and the distorted signal was still coming through the bypassed signal slightly...

So I went further and tried 2n5485's instead

both in q1 and q2 as i believe these are responsible...

does anyone have a definitive fix for this bleed through problem as I understand keeley modded sd-1's have been fixed.

thanks

john

Hi John. I recommend you read this thread http://www.elixant.com/~stompbox/smfforum/index.php?topic=23903.0 (http://www.elixant.com/~stompbox/smfforum/index.php?topic=23903.0)
(if you haven't). It talks about the SD-1 bypass problem and ALOT of good advice
and reports of "fix" attempts. I do not have an SD-1, so I have no first hand experience
with this concern, but I believe you would pick up a few good tips. Also, reply #42
by shredgd seems to be the hot thing. He refers to this mod :http://forum.musikding.de/attachements/Boss_SD-1_mod_c.gif (http://forum.musikding.de/attachements/Boss_SD-1_mod_c.gif)
Well I hope this is of help to you. Good luck.

Tommy

I use to own a sd-1 that i modded and i had the same problem. I tried everything but it just wouldn't go away. :icon_evil: BUT i did find a solution recently. monte allums sells a kit to remedy this problem. I have tried some of his mods and they sound really good so I would trust him on this one. Check it out it might help.

Yes, makes you wonder.

I just tried it myself with a j201 and figured I'd post a diagram in case anyone wants to do it to theirs. I increased the gain tons for experimental reasons and installed this little circuit. Bypass distortion fixed!  :icon_biggrin:

I tried to upload it to my space in the layout gallery but it wouldn't let me log on...it kept asking me to debug an error!

Man, seeing this thread reminds me once again that I need to do this fix to mine.  :icon_lol:  It's had this problem forever and I just never did anything with it.  Could be that I don't use it much.  :icon_mrgreen:

I've been using an SD-1 for years without ever having a problem with this.  Am I the only one?  Are only some units plagued with dist-bleed? (I can't imagine)...

Hello everybody!
I am very happy with my modded sd-1 since i solved the common bleed problem.
All you need is only 1 diode 1 cap and 1 jfet.
As wampcat says it really works! I don't remember the trhead where i find it, infinite thanks for that anyway.
My sd-1 seems to be a true bypass pedal now!
I also made a little diagram
http://togusa.altervista.org/sd1_bleedfix.JPG
copy and paste to another window if link doesn't work.
Sorry for my bad english again.
Ciao...

Yes.. sort of -- I posted this:

and Robert emailed me and told me that I stole that idea off of him. To avoid any issue, I posted this:

Honestly, I just don't want to be blamed for being a thief.

Muting is old

muting has been used in electronics for years, see that button on your TV remote?

Older CD players used BJT mutes on the output lines

BTW kids, you can easily do this sort of thing at home with your DIY stuff with a dpdt/3pdt switch. No need for transistors and etc if there's no electronic switch. No one's patented that idea yet that I know of...

Yeah, anyone remember Frank Clarke?

It's funny watching the modders stake out their territory and square off over something as banal as a mute. On the surface though, I got the biggest kick out of the 'adapting the TS-9 mod to an SD-1' comment. As if that's a stretch... :icon_rolleyes:

The mod biz is always entertaining to watch. I'm getting some popcorn...

I hope I'm not opening a can of worms, but I have heard his name come up alot but any mentions of his website no longer work -- how does Frank Clarke fit into the mod picture?

Thanks,

Wow... and he was accusing me of doing the same thing. Craziness.

:icon_eek:

He DID say that they MADE $250,000 LAST MONTH alone, so I guess he's reaping a fortune off of his cheezy mods.

Great thread, the diagram is very helpful ... and if Keeley claims credit for it, I tip my hat in his general direction.

Does anyone know a Mouser part number for a J201? I tried to look one up but know nothing about the part and became confused.

Thanks.

CD, I'm not sure what your problem is with Brian - he actually contributes here, whereas Keeley does not (he's only ever shown up to post briefly to defend his actions after he ripped off Frank's work or to inject some of his infamous !!!!-laden sentences, not once AFAIK to contribute anything). In my book, regardless of commercial interest, this makes a *big* difference in terms of the respect that should be shown. Keeley is no different to any other mod-boy enterprise, except he acquired critical mass - after jumping on Analog Mike's (another long-term DIY forum visitor / contributor) bandwagon, that is. 4-5 years might be a long time in 'net years' but some of us do remember how things got started and - beyond the hype and sales figures - the ethical and moral basis to events.

Disclaimer: I've had business dealings with Analog Mike and business discussions with Brian in the past.

$250,000!!!

IMO if he's making that much money, he should be greatful for what he's got going, and he should quit bitching about one free DIY forum...its not a threat to him at all.
