Members gambit Posted November 14, 2009 Members Share Posted November 14, 2009 Just looking up some mods.. Keeley posted a few on the bossarea forum: http://www.bossarea.com/forum/topic.asp?TOPIC_ID=635 "The first mod is to remove D6 and D7. You can put them on a switch to toggle this on and off but I think a quick listen will convince you that those can go. These two diodes give a very slight increase in distortion but when removed give you a much livelier and open sound. The reduced gain you'll have is so slight that I think it would only offend those that run this pedal gained to maximum". Remove D6 & D7. seems simple enough.. anyone tried it?

Members jackpotjewell Posted November 14, 2009 Members Share Posted November 14, 2009 I did this and ended up changing it back. I also did the Monte Allums mod and ended up buying another od-3 because I liked it better stock. I recorded clips of the before and after of the keeley mod. Here's a stock OD-3 http://soundclick.com/share?songid=4242856 and here's with the two diodes removed. http://soundclick.com/share?songid=4242883 Link to comment Share on other sites More sharing options...
Members jb1911 Posted November 14, 2009 Members Share Posted November 14, 2009 I did all the mods I could find and the stock pedal sounded best to me. Really Boss' best OD pedal. Link to comment Share on other sites More sharing options...

Without the exact same riff/ progression played through the two comparisons it's somewhat difficult to tell, but the second one sounds a bit cleaner, like there's a sub layer of low end distortion missing.

Yeah only thing different was the riff. It's a strat with kinman woodstock pickups into a 72 twin reverb. Link to comment Share on other sites More sharing options...

Members jackpotjewell Posted November 14, 2009 Members Share Posted November 14, 2009 Yeah the gain is maxed at the end. I don't think the tone was really affected at all, it mostly just sounded like more of the clean guitar came through to me. I didn't try any in-between mods. awesome, thanks for posting those. the mod definitely makes it more transparent/cleaner-sounding. is the last part with the gain cranked? it sounds like there's a significant loss of gain, which i wouldn't have expected from reading Keeley's guide. did you notice any difference in where you have to set the tone after the mod? does it dull or brighten the sound compared to stock? does removing only one of the parts change anything? maybe an inbetween mod?

Members gambit Posted November 14, 2009 Author Members Share Posted November 14, 2009 cool. i like my drives with a transparent/clean blend anyway, so i'm going to give this one a go i think.. wish me luck! Link to comment Share on other sites More sharing options...
Members southpaw pete Posted November 15, 2009 Members Share Posted November 15, 2009 Right on. Keep us posted on how ya like it. I was wondering about trying the mod on mine too. Link to comment Share on other sites More sharing options...
Members echodeluxe Posted November 15, 2009 Members Share Posted November 15, 2009 when you take the clipping diodes out (d6, d7) then you will get more volume and less clipping. thats why it sounds cleaner. i did that mod to mine and went back to stock. stock, this pedal is incredible. needs nothing.

Members Instrospection Posted November 15, 2009 Members Share Posted November 15, 2009 I've found that removing diodes--especially in four diode distortions like the Big Muff--that the tradeoff is a more open, clearer sound with less compression, but the downside is that there's less sustain with that reduced compression. Sounds like that's what's going on with the OD-3. Link to comment Share on other sites More sharing options...

Members gambit Posted November 15, 2009 Author Members Share Posted November 15, 2009 it's easy enough to re-solder these two components back into the circuit board isn't it? considering my level of modding consists of replacing an led with a different colour led.. and turning some trim pots...

Members gambit Posted December 5, 2009 Author Members Share Posted December 5, 2009 So i did the D6/D7 mod on my OD-3. the extreme's of clean and cranked gain are VERY nice, open, unmuffled, 'transparent' :blah: but... with a standard overdrive setting, when you leave a chord hanging and the volume fades out you can hear the gain trying to clamp onto the fading signal and sputtering as it does it. i'm pretty sure this doesn't happen with a stock pedal. so i guess i'm either going to try and fully restore it, or maybe try putting just one of the components back in and see if that works. guys - any idea what exactly D6 and D7 are doing? maybe i can have an educated guess at which to try first :poke: Link to comment Share on other sites More sharing options...
Members Gaetano Paul Posted April 24, 2011 Members Share Posted April 24, 2011 Hey man, I tried this mod, it sounds terrible, what a CRAPPY mode, it sounds like ghost fuzz notes, wow thats bad, I cant beleive this one, transparent!

Yeah right, sounds like a hole in the speaker \nSo pissed Too bad you didn't see this thread 2 years earlier. I recall this thread, as there used to be a lot of OD-3 love on this board (not much lately) and most everyone mentioned the mods made it worse, and that stock is the best way to go with this pedal.

Members fetch Posted April 24, 2011 Members Share Posted April 24, 2011 Stock OD-3 is one of the best pedals evarrrr ;\nI love mine. EDIT: oh wow sucker punched into a vintage thread... BASTORDS Link to comment Share on other sites More sharing options...
Members Gaetano Paul Posted April 24, 2011 Members Share Posted April 24, 2011 It really is great, I read that the mod opens it up a bit more, I figured I could go for some of that, maybe tame the slight harshness, though it is nice in its own right. Stock OD-3 all the way! Link to comment Share on other sites More sharing options...

Members SexyKoala Posted June 22, 2013 Members Share Posted June 22, 2013 I use to think the OD3 was the greatest OD ever made (and you don't try to change something that works), but then I heard a Klon, and from then on I had nothing left to loose with regards to my OD3. So I went ahead and ripped out D6 and D7. To compare the sounds, I recorded a guitar part during a session, (and I can't share it with you, before you ask and rightly so.) and had the D.I. track of the guitar passing through the Radial re-amper, OD3, to a Fender Twin. I was able to send the exact same guitar part with the same settings on everything to compare the result in a studio with and without the mods. Very scientific... So it seems that I don't have a funny ghost distortion or any problems of that sort, and definitly the overall volume went up quite a bit, at least in perception. (Meters also shows me a 3-4 db increase in output volume). I just took out D6 first, and was pretty happy with the mod. Took out D7 too and that makes less of a change. Comparing my recordings (stock vs. mod), its clear to me this mods works, and it totally revived my love for the pedal. Less compression, less gain, less mud, sweeter hi frequencies. Its rounder, yet it still bites like a marshall. I think I also have a better noise-floor too, but I'm not sure. Its dead quiet now. I'm going to keep it modded cause its way more fun to use this way. Its now a versatile boost-gain pedal, that doesn't mess with the guitar tone. I play a low output Strat. Winner mod for me. Works even better in my Epiphone Valve Jr. Link to comment Share on other sites More sharing options...
