AinsleyWalker Posted January 15, 2020 Share Posted January 15, 2020 So I see a lot of people using OC2s with the dry signal and -2 octave all the way off and the -1 octave all the way up. I've had my OC2 for years but whenever I've tried to use it like this, it's been way too quiet, the -1 octave simply isn't loud enough to be used alone and when engaged, there's a significant drop in volume, even when using a powerful amp/cab and a Cali76 compressor in front of it. Am I missing something? I watch demos and it doesn't seem to happen to others. Quote Link to comment Share on other sites More sharing options...
dodge_bass Posted January 16, 2020 Share Posted January 16, 2020 Yup. There’s a mod that involves disconnecting the -2 Oct which increase the output. You can also decrease the dry pot too for further volume however just taking the -2 really sorts out the volume issue and with a bit of dry mixed in it sits great in the mix. It’s a super quick job you just need a good teccy! 1 Quote Link to comment Share on other sites More sharing options...

If so, I'd be very tempted to get another one to replace the one I moved on! 1 Quote Link to comment Share on other sites More sharing options...

I think the pot for that control is broken so that's another repair that needs doing. Maybe I could look for someone who could do both at the same time. Although I've just bought an MXR Bass Octave deluxe and I think that might be more usable, as much as I love the oc2. 1 Quote Link to comment Share on other sites More sharing options...
AinsleyWalker Posted January 16, 2020 Author Share Posted January 16, 2020 @dodge_bass I've also JUST learnt that the old Taiwanese/Japanese OC2s (like mine) which use the Boss ACA adapter need 12v to run properly... So for all these years I think maybe I've been underpowering it and that could be a factor in why it's so quiet?? Gonna test it out 1 Quote Link to comment Share on other sites More sharing options...

I’ve got a couple and I’m sure that one of these is Japanese and I haven’t noticed any difference in the output. Only been running them on 9V.

It’s a pretty simple soldering job so most people who are handy with a soldering iron should be able to do it. Where are you based? Quote Link to comment Share on other sites More sharing options...

I found that the three leaf audio Octabreve is probably the closest emulator of an OC2. I wasn’t a huge fan of the base octave deluxe to be honest - each to their own Quote Link to comment Share on other sites More sharing options...

Yeah I did try running mine on both 9v and 12v but didn't notice any audible difference. But I've checked a few forums and pages and it seems that if it says ACA adaptor not PSU adaptor, then it needs 12v to run properly. But I can't find anything official. 1 Quote Link to comment Share on other sites More sharing options...

That's fair, it's definitely different (which is fine because I wanted an OC2 alternative). it's a bit more of a 'run of the mill octave', which is generally what I'd heard about it and expected, but very beefy so I can see it being very usable, if not slightly less unique than the OC2 1 Quote Link to comment Share on other sites More sharing options...

There must be some amp repairers / technicians nearby that could look over it for you? Quote Link to comment Share on other sites More sharing options...

Yeah most likely, I've not looked into it to be honest. Might do that over the weekend! Thanks for the suggestion Quote Link to comment Share on other sites More sharing options...
