warwickhunt Posted August 26, 2008 Share Posted August 26, 2008 Just got an OBP1 to drop into my Streamer fretless (it has 3 band MEC which I can't get on with... I'm a less is more guy ) and it appears to be an older version as it is wider and flatter than the present OBP1 displayed on the Aguilar site. My question is - can this seemingly older version be run at 18v as the present version can? I've been on the Aggie site to no avail and I can't even find a bliddy link to send them an email! Cheers.

Kev Posted August 26, 2008 Share Posted August 26, 2008 i dont recall there ever being a aggie preamp that couldnt run at 18v, but i could be wrong... Quote Link to comment Share on other sites More sharing options...
spinynorman Posted August 26, 2008 Share Posted August 26, 2008 From various discussions on Talkbass it appears both versions are recommended to be run at 18V, but will actually work ok at 9V if you want. Quote Link to comment Share on other sites More sharing options...

I've just done a search through TB and came to the same conclusion until... [url="http://www.talkbass.com/forum/showthread.php?t=210688&highlight=obp1"]http://www.talkbass.com/forum/showthread.p...;highlight=obp1[/url] This seems to indicate that the OBP1 is 18v only! TBH I have room for 2x9v batteries so I can run it at that and I was more concerned about running something that 'should' operate @ 9v on 18v. Thanks though Quote Link to comment Share on other sites More sharing options...
spinynorman Posted August 26, 2008 Share Posted August 26, 2008 (edited) This one is a discussion about why the OBP-1 needs 18v and the conclusion, apparently supported by Aguilar, is that it can work with 9v, but they don't recommend it. About 2/3rds of the way down is a comment from someone who has the old one, which I read as "it sounds ok on 9v, but should be 18v".

If it ain't going to feck it in the process (which it seems fairly conclusive that it won't) I might try it both ways. In fact I might try to do a simple direct recording onto a digital 4 track and see what it sounds like with the present 18v 3 band MEC pre then the Aguilar @ 9v then 18v Quote Link to comment Share on other sites More sharing options...
Peaty Posted August 26, 2008 Share Posted August 26, 2008 Hello Warwickhunt When the dust has settled if you would consider parting with the MEC pre I have been looking for one. In any case I hope the transplant goes well. Pete Quote Link to comment Share on other sites More sharing options...

I'll give it a blast as soon as I get the pots, at least it'll be obvious if the thing just doesn't work on 9v Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted August 29, 2008 Author Share Posted August 29, 2008 Just an update and bit of info for anyone searching in the future... The early Aguilar OBP1 (slim one not the latest cube type) runs on 18v. Saving the knee trembler when I had no output (I had the + and - reversed when soldered to the jack output), the swap was pretty straightforward and easy with the aid of the diagram from the Aguilar website. Oh and a positive to Warwick for prompt delivery of new pots and knobs. Quote Link to comment Share on other sites More sharing options...
