I learned something today...I think that's true of the bart preamps, which can run 9v or 18v (hence the 918 in the name)
According to Aguilar, OBP1 preamp with FET boost-only design, is both a 9- and 18-volt circuit.
So, if Mr. @Sadowsky says that all is good at 9 volts, I believe him.
And, if Mr. @ragetoca says that all is good at 18 volts, I believe him.
I think that's true of the bart preamps, which can run 9v or 18v (hence the 918 in the name), but as Roger says, his preamps are a very different design. While I can't challenge your experiences, as I've never tried it, FWIW, I would actually expect some kind of difference in the case of Roger's preamps.
That said, it's not the way Roger's preamp was designed to run, so I'm not messing with it... especially since I have absolutely zero issues with it the way it is.
FWIW/IMHO
You don't have anything in your signal chain at all with any kind of gain stages? Maybe you're just using a direct box or something? I guess regardless, I'm very surprised you run with a board that has issues setting input gain like that. Even with the standard output of the Sadowsky, through a passive direct box (I use the Radial JDI sometimes), I've never, ever, had an issue where the sound guy couldn't get the input gain stage set properly.I play in an environment where we don't use any stage amps, is all IEM with no stage noise (no bass or guitar amps), sound guy was always asking me if I could give him more volume (We have a Digico FOH board)...
The player does the most to make the bass sound good, Enrico!![]()
I play in an environment where we don't use any stage amps, is all IEM with no stage noise (no bass or guitar amps), sound guy was always asking me if I could give him more volume (We have a Digico FOH board) and besides I like running my volume at 75%, the 18v gives me more and *cleaner* output (headroom) and I like it!
) and with a good DI and a decent compressor (unfortunately most of the comp pedals work just as limiter You don't have anything in your signal chain at all with any kind of gain stages?

In my case, I'm also IEMs only, two bands and also worship, I always use a Fractal unit as both my processor and also DI box, so I have lots of options for gain staging, but I have also gone super simple at times, with just the JDI and just never had any issues.
Your experiences are what they are, and you do what you gotta' do, I understand that. I guess I'm just glad they aren't mine. I'd hate to have to modify my bass to operate properly in the environment I play in. Don't think I'd even consider it, honestly.
Since I play 3 different sadowsky basses, they don't all have the same output, even my Single Cut seems to be somewhat low output....I had a 2008 M5-24 that had SO MUCH output it was crazy LOUD....by my german moderns are not close at all to it....I also have a Roscoe SKB3005 that I put an 18v Sadowsky Pre with Aguilar DCBs,
, do you have the same pickups on all? Which wood combinations are they?A Will Lee Jazz 5 (Jazz pups), Single Cut M5-25 (Soapbars), Modern M5-24 (Soapbars) All Metroline GermansThat's interesting, do you have the same pickups on all? Which wood combinations are they?
A Will Lee Jazz 5 (Jazz pups), Single Cut M5-25 (Soapbars), Modern M5-24 (Soapbars) All Metroline Germans
I guess the Lee model is the one with more output isn't it? The soapbars are humbckers, J or P?

How does the volume compare when switching to passive? I know early German metrolines had lots of gain, but were modded later to lower level to match closer to passive mode.A Will Lee Jazz 5 (Jazz pups), Single Cut M5-25 (Soapbars), Modern M5-24 (Soapbars) All Metroline Germans
Both J - I think the Moderns are suppose to have more output, not sure! My japanese M5 had so much output, like enough to blow a system up!![]()

Hi Roger,Do you have the gain trim pot on the control plate all the way up??
