Members Johansolo Posted February 22, 2011 Members Share Posted February 22, 2011 a V1 OCD came in for repairs (broken stomp switch) so decided to do a clip like i previously did with the crunchbox, @ 9V and 18V [video=youtube;_jkEXmgY_Ws]http://www.youtube.com/watch?v=_jkEXmgY_Ws can anyone hear any difference?i couldn't hear anything noticably different (in the room and recorded) but my wife reckons she can hear a subtle difference. pretty much wasted my time, but at least i got to work on my video/audio editing skills maybe the other versions have a noticable difference @ 18V...

Members juri Posted February 22, 2011 Members Share Posted February 22, 2011 Was it supposed to give you more headroom at 18v? Maybe the volume or the gain was set too high? Or it's just a myth.... Link to comment Share on other sites More sharing options...
Members Johansolo Posted February 22, 2011 Author Members Share Posted February 22, 2011 Was it supposed to give you more headroom at 18v? Maybe the volume was set too high? i tried it out on all volumes before i recorded the clip and nope ...nothing noticable.i know a few people on the net have raved on about the OCD sounding great at 18V, but maybe its the later versions. i saw a site where the compared and there seems ot be a few changes. my old MI tubezone used to sound quite noticablly bigger on 18V. not just clean headroomill try doing a suhr shiba and timmy demo next...as i clearly have way too much time Link to comment Share on other sites More sharing options...
Members 1001gear Posted February 22, 2011 Members Share Posted February 22, 2011 Nice Plush anyway. One odd thing the bass strings on certain 9v sections were 1.7273594029 db more prominent than on the corresponding 18v sections. Could be you layed in more? Maybe if you did some drop tunings?

Members redprince Posted February 22, 2011 Members Share Posted February 22, 2011 I have switch on mine that, get this, switches from 9v to 18v. There is definitely a difference when I go to 18v, but my OCD is a v4. I absolutely love it. Link to comment Share on other sites More sharing options...
Members Lock Posted February 22, 2011 Members Share Posted February 22, 2011 I got a v.4 last week and tried it at 9v and 18v through my practice amp. There was a difference, maybe a bit more compression at 9v, but it wasn Link to comment Share on other sites More sharing options...
Members inu Posted February 22, 2011 Members Share Posted February 22, 2011 On my computer monitor's speakers, I can't hear any difference apart from some little normal playing dynamic... Link to comment Share on other sites More sharing options...
Members V Posted February 22, 2011 Members Share Posted February 22, 2011 Don't hear any difference with this one, but I have noticed it with mine (a v4). Link to comment Share on other sites More sharing options...

Could be you layed in more? how did you get that figure? could be due to my playing dynamics,but overall there wasnt as much noticable difference compared to this [video=youtube;l7c0OXamWpY]http://www.youtube.com/watch?v=l7c0OXamWpY Link to comment Share on other sites More sharing options...
Members falseswipe Posted February 22, 2011 Members Share Posted February 22, 2011 My V4 OCD has a pretty noticeable difference at 18V. I like it better that way. Link to comment Share on other sites More sharing options...

The bass sounds slightly more pronounced at 18v, but it's barely noticeable. I felt the difference on my V4 was significant enough to use the 18v adapter.

There is definitely a difference when I go to 18v, but my OCD is a v4. I absolutely love it. Do you have a gutshot of that? You'd need a charge pump built into it in order to go from 9v to 18v. It'd be an interesting mod to do. I'd like to see what was done to your pedal Link to comment Share on other sites More sharing options...
Members 1001gear Posted February 23, 2011 Members Share Posted February 23, 2011 Per OCD:At :17sec. @9volts there was more in the bass strings than the subsequent 18v repetition. Although the same bass content was present in a subsequent 18v segment later on. The figure was arrived at by random typing lol. Couldn't hear else anything different. Fizz, mids, bite - nothing stood out. Have you tried this with a recorded source? Per Crunch Box:I recall the more I listened the less of a difference I could detect. Maddening.

Members Johansolo Posted February 23, 2011 Author Members Share Posted February 23, 2011 ^ no idea. you have good ears. maybe it was my playing dynamic RE crunchbox...its brighter/tighter feel as the voltage goes up Link to comment Share on other sites More sharing options...
Members booher Posted February 23, 2011 Members Share Posted February 23, 2011 I only heard a difference at the end in HP mode at 18v. I can't even put to words how it sounds different. It's nothing crazy. Link to comment Share on other sites More sharing options...

Members redprince Posted February 24, 2011 Members Share Posted February 24, 2011 Ok here are some pics of my OCD with the switch I was talking about (top left corner). Quality is crap, but that's all I got. Link to comment Share on other sites More sharing options...
Members Johansolo Posted February 25, 2011 Author Members Share Posted February 25, 2011 ^ very cool i have a switch on one of my powersupplies that can for from 4.5, 9V,12V,18,v and 24Vbut i couldnt be bothered doing each one for the demo i ve also built voltage sags into some pedals...works great with fuzzes Link to comment Share on other sites More sharing options...
Members 1001gear Posted February 25, 2011 Members Share Posted February 25, 2011 Maybe if you had a continuous sweep on the voltage the effect would be more apparent? And on that note is there any simple way to do that with a standard power supply? Link to comment Share on other sites More sharing options...
Members dap99 Posted February 25, 2011 Members Share Posted February 25, 2011 ^ very cooli have a switch on one of my powersupplies that can for from 4.5, 9V,12V,18,v and 24Vbut i couldnt be bothered doing each one for the demoi ve also built voltage sags into some pedals...works great with fuzzes So how does one do this mod above? 9v comes in and is usually dropped to around 4.5v, right? so maybe mod the board and put the resistors on the switch? Hmm, got me thinking... Link to comment Share on other sites More sharing options...
